Q

What is the purpose of the axon?

A

Carry action potential away from the body

17
Q

What are the components of an axon?

A

Myelin sheath
Nodes of Ranvier
Telodendria
Terminal Boutons

18
Q

Myelin sheath function

A

Increase conduction velocity

19
Q

Nodes of Ranvier function

A

Interruptions that allow AP to jump from node to node in order to avoid depolarization of entire membrane

20
Q

Telodenria fuction

A

Expands the axon to allow more synapses to form on 1 axon

21
Q

Terminal boutons function

A

Site of synapses

22
Q

How would you classify a neuron that is one process attaching to a cell body

A

Unipolar

23
Q

Which classification of neurons are not found in human systems?

A

Unipolar

24
Q

What is a Pseudounipolar neuron?

A

Two processes attach to cell body, but they are close together and look like 1 process

25
Q

What classification of neurons is found in the general sensory system?

A

Pseudounipolar

26
Q

How would you classify a neuron that has two processes attached to a cell body at opposite ends

A

Bipolar

27
Q

Where would you find bipolar neurons?

A

Special sensory systems (retina, auditory)

28
Q

What is a multipolar neuron?

A

Cell body has numerous processes attached to it

29
Q

Where do you find multipolar neurons?

A

Motor systems
