What is the difference between a motor neuron to skeletal muscle and the term motor neuron?
97936
Most likely it means a variety of things.  A neuron is a pathway - in whatever subject you are delving in.  It could be the motor neuron from the spine that runs through the cerevbral cortex and into the appropriate site in the brain; the motor is as all motors- it is a source of power - could be a motor of any type, but in this case one is referring to the nerve that causes the firing impulse along the neural pathway to the brain that causes a muscle to contract.  \nThe other is probably speaking of a specific motor neuron - there are billions in the body.

Skeletal muscles are voluntary muscles attached to your bones like your biceps, etc. Smooth muscle is involuntary muscle such as that in the heart or stomach.

I'll try to answer this question without writing a thesis or dissertation.  Skeletal muscles have an origin, insertion, and tend to cross an axis point.  For example, the two muscle that make up the bicep originates from a point underneath the front deltoid.  They insert below the elbow and move the lower part of the arm inward to your body.  This is done through the brain sending a signal to the muscle to move.  These signals are neurons, which travel along the nerve pathways.  So the brain thinks bring the hand to the shoulder and the bicep moves your lower arm inward.  This is pretty much consistent with the other skeletal muscles in the body.  The brain sends signals that tell the muscle to contract or extend.  Well that is about as simple as I can put it.  I'm sure someone else can probably elaborate and give a better explanation.

The sets of muscles that have the finest control have the fewest muscle fibers per motor unit.  This makes sense because when a neuron depolarizes all of the muscle fibers it is connected to depolarize and contract.  This is refered to as a "All-or-None" response.  Muscle fibers don't contract half way.  So if you want precise control over your muscles you have to have a lot of neurons innervating it.

That's a very interesting question, especially considering that muscular dystrophy mainly affects boys, and dyspraxia is more common in males, as well as them both involving muscular dysfunction... I've done a quick literature search (pubmed, medline), which revealed nothing about a possible link. They do appear to have separate etiological and biological origins though, with dyspraxia likely being a dysfunction of neural connections, while DMD is more of a killing/atrophy of muscle fibres, i.e. dyspraxia is a brain dysfunction, DMD a muscular dysfunction. This does not exclude the possibility of a relationship however, and it may be of interest to researchers in the field of movement disorders... \n\nAll the best, hope that helps somewhat!

somatic (which means body) sensory neurons gather the input or the stimulus of an event while motor neurons react to the stimulus...\nsay you put your hand on a hot stove...the neurons on your hand detect the heat and send the message up to your brain...your brain encodes the message saying that it's too hot and if you keep your hand there it will cause pain and damge your body...so the brain activates the motor neurons to make your hand react (it makes your hand pull away so that your hand isn't minimally damaged)...this process takes milliseconds!

I looked this one up in my neuroscience book. Thought I'd add to the above answer. \n\nIt looks like it is hierarchical because of the motor subsystems. Two of these subsystems are Lower and upper motor neurons. Upper are located in the brainstem or cerebral cortex while lower send axons out of the brainstem and spinal cord. Third and forth subsystems regulation teh upper motor systems. Third, cerebellum, forth basal ganglia. \n\nThe interactions are more detailed and too much to type. Good luck. \n\nBTW: I like these sorts of questions.

I. COMPARISON OF SOMATIC AND AUTONOMIC NERVOUS SYSTEMS (ANS)\n\n     A. Sensory neurons of the somatic nervous system receive input from the special senses, general somatic senses, and proprioceptors; sensory neurons of the ANS receive input from the special senses, general visceral senses, and general somatic senses.\n\n     B. The somatic nervous system operates under conscious control; the ANS operates without conscious control.\n    \n     C. The axons of the motor neurons of the somatic nervous system extend from the CNS synapse directly to an effector and release acetylcholine, whereas autonomic pathways consist of two sets of motor (efferent) neurons.\n\n        1. The axon of the first (preganglionic) motor neuron of the ANS extends from the CNS and synapses in a ganglion with the second neuron.\n        2. The second (postganglionic) motor neuron synapses on an effector. Preganglionic fibers release the neurotransmitter acetylcholine and postganglionic fibers release acetylcholine or norepinephrine. \n\n     D. Somatic nervous system effectors are skeletal muscles, and ANS effectors include cardiac and smooth muscle, and glands.\n    \n     E. The somatic nervous system responds to neurotransmitters as excitation while the ANS response to neurotransmitters is excitation or inhibition.\n\n     F. A summary of the similarities of and differences between the somatic and autonomic nervous systems is presented.\n\n     G. The output (efferent) part of the ANS is divided into two principal parts: the sympathetic and the parasympathetic. Organs that receive impulses from both sympathetic and parasympathetic fibers are said to have dual innervation. III. \n\nANATOMY OF AUTONOMIC MOTOR PATHWAYS\n\n     A. Overview\n\n        1. Preganglionic neurons are myelinated; postganglionic neurons are unmyelinated.\n         2. The first of two autonomic motor neurons is called a preganglionic neuron.\n             a. Its cell body is in the brain or spinal cord.\n             b. Its myelinated axon, called a preganglionic fiber pathway, passes out of the CNS as part of a cranial or spinal nerve, later separating from the nerve and extending to an autonomic ganglion where it synapses with the postganglionic neuron.\n        3. The postganglionic neuron pathway, the second neuron in the autonomic motor circuit, lies entirely outside the CNS.\n            a. Its cell body and dendrites are located in an autonomic ganglion, where it makes synapses with one or more preganglionic fibers.\n            b. The axon of a postganglionic neuron, the postganglionic fiber, is unmyelinated and terminates in a visceral effector. \n         4. The cell bodies of sympathetic preganglionic neurons are in the lateral gray homs of the 12 thoracic and first 2 or 3 lumbar segments; the cell bodies of parasympathetic preganglionic neurons are in cranial nerve nuclei (III, VII, IX, and X) in the brain stem and lateral gray horns of the second through fourth sacral segments of the cord.\n         5. Autonomic ganglia are classified as:\n              a. sympathetic trunk (vertebral chain) ganglia (on both sides of spinal column)\n              b. prevertebral (collateral) ganglia (anterior to spinal column);\n              c. parasympathetic terminal (intramural) ganglia (near or inside visceral effectors). 6. In addition to autonomic ganglia, the ANS contains autonomic plexuses. \n\n     B. Sympathetic and Parasympathetic Divisions\n\n         1. Sympathetic preganglionic neurons synapses with postganglionic neurons in ganglia of the sympathetic trunk or prevertebral ganglia.\n         2. Parasympathetic preganglionic neurons synapses with postganglionic neurons in terminal ganglia.\n        3. The salient anatomical features of the sympathetic and parasympathetic divisions are compared. \n\nTransmission of Autonomic Stimuli\n\nLike other nerves, those of the autonomic nervous system convey their messages to the appropriate end organs (blood vessels, viscera,

Nervous system is devided in to two parts: central(CNS) and peripheral nervous systems(PNS).CNS is the brain and the spinal cord,PNS is composed of many nerves that contains neurones (nerve fibers),these neurones are of two types,Efferent(sensory) neurones carry the messages from the different body organs to the CNS,while the afferent(motor) neurones carry the messages from the CNS back to the different organs. When any part of the system is stimulated by any stimulant;whether it is external or internal,this stimulation will be carried as a message to the CNS where it is translated and then appropriate action is planned, this action then is carried by the motor neurones back to target cells or organs to carry on the plan of action tward that stimulant...It's  a complicated process that really shows the power of the creator who designed it---our lord

All animals have a charged neuromuscular system. Thatis what allows for normal contractions of your bodies muscles. Every time a muscle contracts for what ever reason there is a polority shift and a measurable amount of current flows through your nerve and the muscle that is to contract.

Neurons are a major class of cells (parenchyma) in the nervous system whose main role is to process and transmit information. In vertebrate animals, neurons are found in the brain, the spinal cord and in the nerves and ganglia of the peripheral nervous system.\n\nNeurons are typically composed of a cell body, a dendritic tree and an axon. In the classic view of vertebrate neuron function, the cell body and dendritic tree receive electrical signals from other neurons while the axon transmits electrical output signals. For invertebrate neurons, the information flow is less well defined.\nYOUR QUESTION:\nAre they the motor end plates of the effector neurones?\nYES:\nNeurons are able to generate and propagate electrical impulses because they have excitable membranes. Neurons make connections with other neurons and transmit information to them via synaptic transmission. Different types of neurons have different shapes(Like Plates), possess specific electrical properties adopted for their function and use different neurotransmitters.

Simply there is a domain a cell can do. Different cells do different things. You can't get a neuron to make insulin.

The sympathetic nerves arise in the brain in the reticular formation, a diffuse set of nuclei (cell bodies in the brain or spinal cord) and send axons (bioelectrical transmission lines) the the lateral horn of the spinal cord.  The reticular formation receives incoming pain signals as well as higher input from the hypothalamus, cortex and elsewhere.  The axons descending to the lateral horn snynape (form chemical connections that communicate with the next neuron by chemicals known as neurotransmitters) with the cell bodies of motor neurons.  These motor neurons send myelinated (myelin is a biological insulator) axons to the ganglia (collections of cell bodies outside the brain and spinal cord) for the sympathetic nervous system.  These ganglia include a long chain that entends from the cervical to the lumbar regions, plus other ganglia in the head and adbominal cavity.  This synapse typically releases the neurotransmitter, acetylcholine, which acts on nicotinic type "N" receptors - nicotinic-ganglionic receptors.   Nicotinic "N' receptors are distinguished from nicotinic "M" receptors (the neuromuscular junction) that serve skeletal muscle by differing responsiveness to pharmacological agents.  The post-synaptic (cell that receives the chemical signal) neurons are not mylenated and project to the visceral organs, skin, and blood vessels where they release neurotransmitters (norepinephrine or, in the case of skin, acetylcholine) that act on the effector organs.

The combination of a single motor neuron and all the muscle fibers it innervates is called a motor unit. Synapse takes place at the motor end plate.

In what respect?\nYet more general questions asked by inquisitive ... erm.... well... I shall try to answer...\n\nThey are both substancial collections of atoms... formed into molecules... mostly water though a fair number of hydrocarbons and amino acids, among other similar structures. \nThey're both animal cells...  presumably human animal cells in this case... That means they have a cell membrane, nucleus, mitochondria and various smaller organelles.\n\nAside from that, we have the specifics of those cells:\nThey're both rather skinny for one thing... lengthy and skinny. Neurones... i.e. nerve cells.... can however be easily as long as the entire length of your forearm... and yet thinner than most cells. Sperm are very much smaller than that. \n\nFeature-wise... nerve cells have dentrites... branching extensions of the cell membrane... at each end. These are to connect to other neurones and transmit signals between them. The signals are transferred through the cell itself along the axon... which is the long, thin bit in the middle.... by means of an ionic differential gradient between potassium and sodium ions. In almost all cases, neurones will be found in bundles (since they're so thin) to cover a wide area and send as much data as possible to and from the brain.\nThere are different kinds of neurones that serve different functions.... in particular motor neurones (which transmit data from the brain to the body)  ... well... whatever the opposite ones... sensory neurones maybe... (which, by whatever name, transmit data from the sensory organs to the brain)... and interneurones... which join the others together inbetween.  As I recall, the neurones in the brain are of different types again, but I don't know the slightest thing about those.\nAnyhow... I don't think I can tell you much more about nerve cells.\n\n\nSperm on the other hand... are male gametes.... produced in vast numbers at very little bodily expense per cell. Each one is basically just a haploid nucleus (one copy of each chromosome) with a flagellum (a 'tail' to propel the cell forward) and just enough cytoplasm and mitochondria to power it for a short journey. They are generated at quite an alarming rate in the testes.... and their entire purpose is to be ejaculated into the female reproductive system and propel themselves forcefully and rather erratically to an awaiting ovum.... Eventually, of the ones that reach the ovum (most die along the way due to the corrosive substances which coat the inside of the uterus), one will get chemically accepted by the larger cell and allowed to fuse the cytoplasms together. The nuclei will then fuse into a single diploid (2 of each chromosome) nucleus.... and the newly fertilised cell will begin to divide.  Note however that while the nucleus of the sperm is allowed to fuse with the nucleus of the ovum... the mitochondria that are in the sperm will be destroyed by the new host cell.... hence all the mitochondria you will ever have are near-identical copies of your mother's ones (not perfect copies since mutations can and will occur between generations).\n\n\nRight... I've had enough of answering this question now...\nOff to other things.

Depends on the reflex. Myotatic is the simplest. One synapse.\n\nAfferent Ia axon (originating in a muscle spindle) enters the spinal cord and synapses on an alpha motor neuron innervating the same muscle, causing it to fire. This reflex mediates the "knee-jerk" your doctor checks for.\n\nhttp://academic.uofs.edu/faculty/kosmahle1/courses/pt351/lect351/reflxarc.JPG\n\nExample in picture form.

I should know this because I teach an MCAT biology course, but it's just escaping me right now.  I think smooth muscle uses a different protein complex to acheive contraction.  It is very similar to myosin, but definately distinct.
