Patho unit 2 Neurons and CNS/PNS

Question 1

Includes the brain and spinal cord

Answer 1

the Central Nervous System (CNS)

Question 2

In charge of rapid functions and activities

Answer 2

The nervous system

Question 3

Includes all neurons outside of the brain and spinal cord

Answer 3

The Peripheral Nervous System (PNS)

Question 4

Divisions of PNS

Answer 4

Somatic, Autonomic, Enteric

Question 5

Somatic NS

Answer 5

voluntary control of skeletal muscle

Question 6

Enteric NS

Answer 6

in the gut, digestive functions

Question 7

Autonomic NS (ANS)

Answer 7

Involuntary functions, divided further into parasympathetic and sympathetic

Question 8

Sympathetic NS

Answer 8

“fight or flight” response, catabolic( break down, release energy), counter-regulatory (raises bp and blood glucose)

Question 9

Parasympathetic NS

Answer 9

“rest and repair” or “rest and digest”

anabolic (builds, requires energy), regulatory ( lowers bp, and bg)

Question 10

Types of neurons

Answer 10

Sensory, Motor, Associational

Question 11

Sensory Neurons

Answer 11

carry information from environment to body and from body to CNS.

Question 12

Ascending pathway

Answer 12

also called afferent pathway, carries sensory info from body to CNS.
Travels up the dorsal(back) of spinal cord

Question 13

Motor Neurons

Answer 13

Carry info from CNS to body

Question 14

Descending pathway

Answer 14

also called efferent pathway, carries info from CNS to body. Travels down ventral (front) of spinal cord

Question 15

Associational neurons

Answer 15

connect neurons to neurons
