Peripheral nervous system (sensory pathways, motor pathways)

Question 2

Autonomic nervous system

Answer 2

Part of the PNS, controls body’s autonomic or involuntary functions, controls BP, cardiac function, bladder, temperature

Question 3

Neurochemical transmission

Answer 3

Process of chemical signaling between cells, synthesis of chemical signals, stored in nerve terminal, released from the nerve endings, bound to a receptor

Question 4

Parasympathetic nervous system

Answer 4

Anatomically and physiologically separate to allow influence of each as needed in the body.
Neural pathways frequently travel together and allow for parasympathetic or sympathetic influence. (Thorax, abdomen, pelvis)

Question 5

Craniosacral

Answer 5

Originate in cranial and sacral regions

Question 6

What does stimulation of PNS cause?

Answer 6

Rest and digest influence

Question 7

Acetylcholine

Answer 7

The neurotransmitter that initiates PNS responses (enables vagal nerve stimulation)

Question 8

Vagus nerve

Answer 8

Cranial nerve X; decreases the rate and contractility of the heart

Question 9

What symptoms are caused by the parasympathetic nervous system?

Answer 9

Decreased HR, bronchocontriction, increased GI smooth muscle activity, digestive enzymes, pupillary constriction, salivation, hypotension, urine production

Question 10

Sympathetic nervous system

Answer 10

Connected with CNS through spinal cord, stimulation causes fight - flight response
Epinephrine, norepinephrine

Question 11

Thoracolumbar

Answer 11

Originates in thorax and lumbar regions
