Review Questions And 100% Verified
Answers
1. Name and describe the parts of a neuron and
explain their function
a. Soma – cell body –
contains the
nucleus
b. Dendrites – receive
messages from other
neurons
c. Synapse – space
between terminal
buttons
d. Axon – long, thin tube that
carries information from the cell
body to the terminal
buttons
i.Message that is carried is called the action potential
e. Myelin Sheath – fatty substance that provides insulation for the
axon and helps axons
transfer messages faster
f. Node of Ranvier - the space between
myelin clusters
2. Describe the different types of glial cells and their specific function (e.g.,
astrocytes, oligodendrocytes, Schwann cells)
a. Glial
cells

messages so
they don’t get
scrambled

and repair
neurons

synaptic
communication
