What are the five parts of a neuron?

Answer 1

The four major parts to the neuron are the dendrites, soma, axon hillock and terminal boutons.

The dendrites receive input from other neurons, and integrate this information into the cell. They may result in either temporal or spatial summation which may result in depolarization of the cell.

The soma, or cell body of the axon contains all of the organelles of the cell - the nucleus, mitochondria, etc. and is important for maintenance of the neuron.

The axon hillock is the area of the cell with the highest number of ion channels present in the membrane, and also is the area of the cell that demarcates the start of the axon. From here, upon summation of stimuli, an action potential can be generated by the massive influx of ions into the cell, resulting in the generation of the action potential which is propagated through the axon.

At the terminal bouton, this is where the action potential triggers a response. Using the neuromuscular junction as an example, when the action potential reaches the end of the terminal bouton, Ca2+ influx is triggered at the endplate resulting in the release of neurotransmitters, in this case, Acetylcholine, which causes contraction in the muscle.

Answer 2

The cellular body, Going away from the body carrying the action potential is the axon. Coning into the body carrying signal from other neurons is the dendrites. In the gap between the end of the dendrite and the receiving neuron is the synapses.

Answer 3

The soma, nucleus, dendrites. axon, myelin sheath and the bouton.

Answer 4

* synapse * axon * motor end plate * cell body * myelin sheath * dendrites

Answer 5

axon dendrite cell body nucleus myelin sheath

Answer 6

Neurons, or nerve cells, are the core of the nervous system. The five main parts of each one of them are the Dendrites, the Nucleus, the Soma, the Axon and the Terminal Buttons.

Answer 7

The parts of a neuron are:

1.dendrites

2.soma

3.nucleus

4.axon

5.node of ranvier

6.myelin sheath

7.schwann cell

8.axon terminal

Answer 8

The 6 major parts of a neuron are: 1) Soma 3) Dendrites 4) Axon 5) Myelin 6) Sheath 7) Bouton (And of course the nucleus which every cell has)
