what is the function of the axon terminal quizlet?
447357
The very end of a branch of a nerve's axon, a long slender nerve fiber that conducts electrical signals to a nerve synapse (the gap between nerve cells). The axonal terminals are specialized to release the neurotransmitters of the presynaptic cell.

Axon terminals contain synaptic vesicles that store the neurotransmitter for release at the synapse. This makes multiple synaptic connections with other neurons possible. Sometimes the axon of a neuron may synapse onto dendrites of the same neuron, when it is known as an autapse.

What is the function of synaptic vesicles inside axon terminals? Storage of neurotransmitter. This vesicles fuse with the membrane when the action potential takes place. ... Then, it's reuptaken in the axon so as to be stored again into vesicles for another cycle to begin.

Nerves. Nerves are bundles of axons in the peripheral nervous system (PNS) that act as information highways to carry signals between the brain and spinal cord and the rest of the body. Each axon is wrapped in a connective tissue sheath called the endoneurium.

Most axons are covered with a fatty material called________________ , which insulates the fibers and increases the speed of neurotransmission.

Nerve impulse release Neurotransmitters are packaged into synaptic vesicles that cluster beneath the axon terminal membrane on the presynaptic side of a synapse. The axonal terminals are specialized to release the neurotransmitters of the presynaptic cell.

The primary components of the neuron are the soma (cell body), the axon (a long slender projection that conducts electrical impulses away from the cell body), dendrites (tree-like structures that receive messages from other neurons), and synapses (specialized junctions between neurons).

An axon terminal is any of the button-like endings of axons through which axons make synaptic contacts with other nerve cells or with effector cells. At the axon terminal, synaptic vesicles containing neurotransmitters are docked.

Neurons, or nerve cells that carry nerve impulses, are made up of the cell body, the axon, and several dendrites. Signals move across the synapse, the place where the axon of one neuron meets the dendrite of another, using chemicals called neurotransmitters.

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...

The action potential travels rapidly down the neuron's axon as an electric current. A nerve impulse is transmitted to another cell at either an electrical or a chemical synapse.

THE BASIC FUNCTIONAL UNIT OF THE NERVOUS SYSTEM IS THE NEURON. WHAT IS THE MAJOR FUNCTION OF THIS CELL TYPE? TO TRANSMIT AND GENERATE MESSAGES (NERVE IMPULSES) FROM ONE PART OF THE BODY TO ANOTHER.

The axon terminal is half of a synapse. A synapse is the connecting structure between two neurons. It includes the axon terminal (the “presynaptic bouton”), the synaptic cleft (a tiny gap), and the dendritic terminal or dendritic spine (the “postsynaptic bouton”).

Axon terminals. End of axon and beginning of junction with other cells where messages are transferred cia chemicals called neurotransmitters—- transfers to dendrite.

Most neurons have a cell body, an axon, and dendrites. The cell body contains the nucleus and cytoplasm. The axon extends from the cell body and often gives rise to many smaller branches before ending at nerve terminals. Dendrites extend from the neuron cell body and receive messages from other neurons.

-Dendrites-receive information form other neurons and transmit electrical stimulation to the soma. -Soma-signals from dendrites are joined and passed on. -Axon Hillock-controls the firing of the neuron. -Axon- transmits the neural signals.

A neural pathway is the connection formed by axons that project from neurons to make synapses onto neurons in another location, to enable a signal to be sent from one region of the nervous system to another. Neurons are connected by a single axon, or by a bundle of axons known as a nerve tract, or fasciculus.
