Q

What is the Peripheral Nervous System (PNS) and what occur here

A

Neurons transport sensory input toward
CNS & motor output away from CNS
* Includes cranial and spinal nerves

19
Q

We have the saying sensory in motor out what would be the sensory in?

A

afferent

20
Q

We have the saying sensory in motor out would be the motor out ?

A

Efferent (motor) division

21
Q

What would be nerves called that are associated with the body regions they server ORGANS?

A

Visceral functions

22
Q

What would be nerves called that are associated with the body regions they server NOT ORGANS?

A

Somatic functions

23
Q

What structure of cell is mostly CNS and is motor Nerouns and internerouns

A

Multipolar structure

24
Q

Describe the shape of a bipolar neuron? If you have to draw.

A

single dendrite, one axon attached to cell body

25
Q

Describe Unipolar

A

This is single axon created via the process to the cell body

26
Q

What are unipolar neourns typically

A

sensory neurons

27
Q

Temporal lobe takes in what?

A

sound and sensory information from the inner ear. You also receive smell from the nasal cavity

28
Q

what is the primary olfactory cortex ?

A

Sensory and smell

29
Q

Occipital lobe

A

receives information from the eye

30
Q

What is the insula involved with ?

A

taste

31
Q

When your sick why don’t things taste as good?

A

Taste and smell are next to each other in the brain
