Cells of the Nervous System

Question 1

consist of cell body (soma), dendrites
(input), and axon (output).

Answer 1

Neuron

Question 2

Junction where signals are passed
from one neuron to another

Answer 2

Synapse

Question 3

Three types of Neuron:

Answer 3

Multipolar, Bipolar, Pseudo-unipolar

Question 4

Many dendrites,
one axon (e.g., motor neurons).

Answer 4

Multipolar

Question 5

One dendrite, one
axon (e.g., sensory neurons in
retina).

Answer 5

Bipolar

Question 6

Single projection divides into two
branches (common in sensory neurons) CNS Glial

Answer 6

Pseudo-unipolar

Question 7

Three CNS Glial Cells:

Answer 7

Astrocytes, Oligodendrocytes, Microglia

Question 8

Form blood-
brain barrier, support neurons,
and regulate nutrient
exchange.

Answer 8

Astrocytes

Question 9

Produce
myelin sheaths for CNS axons.

Answer 9

Oligodendrocytes

Question 10

Act as immune
cells within the CNS, removing
debris and pathogens

Answer 10

Microglia

Question 11

Two PNS Glial Cells:

Answer 11

Schwann cells, Satellite cells

Question 12

insulates axons, enhancing transmission speed of impulses.

Answer 12

Myelin Sheaths

Question 13

Form myelin around PNS axons, aiding in signal
transmission.

Answer 13

Schwann cells

Question 14

Support neuron cell bodies within ganglia,
regulating their environment

Answer 14

Satellite cells
