9

What parasympathetic receptor is found in the ciliary smooth muscle? (slide 12)

Muscarinic receptor (M3)

10

What is the response time of the parasympathetic (cholinergic) system for the ciliary smooth muscle? (slide 12)

1 – 2 sec response time

11

B2 Receptor is found in the parasympathetic ciliary smooth muscle. (T/F) (slide 13)

False (found in the SYMPATHETIC)

12

What is the response time of the sympathetic (adrenergic) system for the ciliary smooth muscle? (slide 13)

20 – 40 sec response time

13

What are the two systems in the enteric division? (slide 14)

Submucous (Meissner’s) plexus & Myenteric (Auerbach’s) plexus

14

What does the hormone Vasopressin do? (Slide 7)

Helps the body regulate thirst and blood volume

15

During stress response, what does the anterior pituitary gland release? (slide 9)

ACTH

16

(T/F) Cortisol deactivates energy reserves. (slide 9)

False

17

(T/F) The sympathetic nervous system dilates your pupils (slides 10)

True

18

What hormones do the sympathetic system release? (slide 10)

EPINEPHRINE and NOREPINEPHRINE

19

What rare disease mentioned in lecture inhibits the release of cortisol? (slide 9)

Addison’s disease

20

Where do the Parvocellular cells of the anterior pituitary DIRECTLY release their hormones? (Slide 8)

Into the capillary beds

21

(T/F) Cortisol activates the immune system. (slide 9)

False

22

In the Dopamine system, where does the substantia nigra lead to? (slide 17)

Basal Ganglion

23

(T/F) The ventral tegmental area leads to the basal ganglion

False! To the frontal lobe

24

Which structure in the brain does norepinephrine leave from? (slide 15)

Locus coeruleus

25

What structure produces serotonin? (slide 16)

Raphe nuclei

26

What structure produces ACH? (slide 18)

Pontomesencephalo tegmental complex

27

(T/F) In reference to the SSRI’s, serotonin is taken up quicker than usual.

False!

28

The kidney releases _____, while the liver releases _____.

Renin, angiotensin

29

What significant roles does cortisol have?

It helps support immune system. It uses feedback control to the hypothalamus to shut down the release of ACTH.

In Parkinson's disease, which part of the brain is affected to cause the symptoms?

Substantia nigra, decreased dopamine release
