What is the basic structure of a neuron?

Answer 1

A neuron consists of three major parts: The dendrites, cell body, and axon. Most, though not all, axons are covered with myelin sheath which is made up of glial cells. The ends of axons are further divided into axon terminals. The axon terminal of one neuron and the dendrites of another is separated by the synaptic cleft.

Answer 2

- Dendrites (covered with receptors) - receive nerve signals from other neurons

- Soma (cell body of the neuron) - accumulates membrane potentials (depolarizing induces an action potential, hyperpolarizing inhibits an action potential)

- Trigger zone (in the axon hillock) - is responsible for the "threshold" function of the neuron. Somatic potentials have to increase beyond the trigger threshold to allow for induction of the action potential in the axon

- Axon - propagates the action potential

- Terminal buttons - receive the action potential, triggering the influx of calcium ions through calcium ion channels, which trigger exocytosis of presynaptic vesicles (containing neurotransmitters), which releases the contained neurotransmitter into the synaptic gap

Answer 3

the nucleus, dendrites, soma (cell body), axon, myelin sheath, node, axon terminals, synaptic (terminal) button, and the synapse.
