Chapter One: Structure and Function Pt.2

Question 1

What are the cells of the nervous system?

Answer 1

Neurons (Nerve Cells) and Glial Cells (Glia)

Question 2

What are the 4 principle divisions of the neuron?

Answer 2

1. Input Zone
2. Integration Zone
3. Conduction Zone
4. Output Zone

Question 3

What are the 4 types (shapes) of Neurons?

Answer 3

Multipolar
Unipolar
Bipolar
Interneurons

Question 4

What are the 2 types of embedded proteins found on a neuron? Can you describe them?

Answer 4

Channel Protein and Signal proteins

A channel protein is where molecules can directly pass to go into the cell (ions)

A signal protein sends a signal to the interior of the protein when a molecule binds to the exterior of the membrane

Question 5

What is the circuit that neural impulses follow?

Answer 5

1. Presynaptic membrane
2. Synaptic cleft
3. Postsynaptic membrane

Question 6

What is included in the Grey matter?

Answer 6

Cell bodies, dendrites, terminals, and unmyelinated axons

Question 7

What is included in the white matter?

Answer 7

Myelin , Axons

Question 8

Clusters of cell bodies are referred to as in different parts of the nervous system?

Answer 8

Nuclei in the CNS

Ganglia in the PNS

Question 9

Bundles of axons are referred to as

what in the different part of the nervous system?

Answer 9

Tracts in the CNS

Nerves in the PNS

Question 10

What is the best way to remember Afferent and Efferent signaling?

Answer 10

A is for arrive so it sends sensory information TO the brain

E is for exit so it sends motor information FROM the brain
