what are dendron and dendrite?
449391
Dendrites are the short branched extension of a nerve cell, along which impulses received from other cells at synapses are transmitted to the cell body. Dendrites usually receive signals while axons usually transmit them. Dendron is a synonym of the word dendrite.

Answer and Explanation: Axons and dendrites are both extensions or projections from the cell body. Both can be part of a neuron and both are responsible for transmitting the...

Neurons have TWO "processes" called axons and dendrites.... glial cells have only ONE. Neurons CAN generate action potentials... glial cells CANNOT.

Ligand-gated channels, located at sites of synaptic contact are found predominantly on dendritic spines, dendrites and somata of nerve cells, or neurons.

Dendrites receive electrochemical impulses from other neurons, and carry them inwards and towards the soma, while axons carry the impulses away from the soma. 2. Dendrites are short and heavily branched in appearance, while axons are much longer.

Some neuron remain bipolar, in which case the two processes may be axons (cochlear nerve & retina) or axon & dendrite (olfactory neurons). Unipolar neurons are primary sensory neurons that have their cell bodies in spinal or cranial nerve ganglia.

Axons transmit information from the neuron on to other neurons to which it is interconnected. To speed up the transmission of electrical signals along the axon, many axons are covered in a myelin sheath. Dendrites receive information transmitted by the axons of other neurons.

Some neuron remain bipolar, in which case the two processes may be axons (cochlear nerve & retina) or axon & dendrite (olfactory neurons). Unipolar neurons are primary sensory neurons that have their cell bodies in spinal or cranial nerve ganglia. ... Multipolar neurons come in a variety of shapes.

During spatial summation, a neuron receives multiple inputs from different sources in physically different locations on the dendrites. However, during temporal summation the neuron receives information separated by gaps in time.

A useful analogy is to think of a neuron as a tree. A neuron has three main parts: dendrites, an axon, and a cell body or soma (see image below), which can be represented as the branches, roots and trunk of a tree, respectively. A dendrite (tree branch) is where a neuron receives input from other cells.

Some types of neurons have no axon and transmit signals from their dendrites. In some species, axons can emanate from dendrites known as axon-carrying dendrites. ... The swollen end of a telodendron is known as the axon terminal which joins the dendron or cell body of another neuron forming a synaptic connection.

Merlinite, also known as Dendritic Opal is a form of common Opal and the white of it has a milky opalescence about it. This is not to be confused with Dendritic Agate which to some can look similar only is denser and has a look about it of Tree Agate. Dendritic Opal is beautiful. It has an inner glow.

Unipolar neurons are sensory neurons - conducting impulses into the central nervous system. Bipolar neurons have two processes - one axon & one dendrite. These neurons are also sensory. For example, biopolar neurons can be found in the retina of the eye.

Depolarizations in dendrites and the cell body generally spread in this manner, though some dendrites conduct an action potential. Neurons with very short axons also conduct axonal depolarizations by passive spread. However, passive spread does not allow propagation of electric signals over long distances.

Dendrites are limited to a small region around the cell body while axons can be much longer. Structure. Substantial structural differences exist between dendrites and axons. ... Dendrites usually receive signals, while axons typically transmit them.

The dendrites receive impulses from sensory receptors or other neurons and send them towards the cell body, which contains the nucleus. Impulses are then conducted along the axons full length away from the cell body to connect with the dendrites of another neuron, muscle, organ or gland of some kind.
