Q

alpha 1 signal transduction pathway

A

Gq, stimulate PLC, second messengers DAG and IP3, increase intracellular Ca levels

19
Q

alpha 2 signal transduction pathway

A

Gi, inhibit adenyl cyclase, second messenger cAMP

20
Q

beta 1-3 signal transduction pathway

A

Gs, stimulate adenyl cyclase, second messenger cAMP

21
Q

who proposed the tale of two transmitters

A

Sir Henry Dale

22
Q

which sites are predominantly sympathetic?

A

arterioles, veins, sweat glands

23
Q

muscle on inner part of eye

A

circular muscle

24
Q

muscle on outer part of eye

A

radial muscle

25
Q

pupillary constriction: muscle, mechanism, system, receptor

A

circular muscle, constriction, PSNS, M3

26
Q

pupillary dilation: muscle, mechanism, system, receptor

A

radial muscle, constriction, SNS, alpha 1

27
Q

what is glaucoma?

A

increased ocular pressure in the eye, specifically increased secretion of aqueous humor, decreased outflow of aqueous humor

28
Q

ciliary muscle glaucoma treatment

A

M3 agonist pilocarpine, outflow of aqueous humor

29
Q

ciliary body glaucoma treatment

A

alpha 2 agonist brimonidine, inhibit production and increase outflow aqueous humor

30
Q

ciliary epithelium glaucoma treatment

A

beta antagonist timolol, inhibit production aqueous humor
