-ion channel
-gpcr
-enzyme linked receptor
-intracellular receptor

Question 2

what is the g protein second messenger system

Answer 2

1st messenger (extracellular signal)
receptor (responds to extracellular signal)
g protein (turns on or turns off an effector)
effector (activates or inhibits the second messenger)
second messenger (primary intracellular signal
enzymatic cascade (a bunch of steps you dont have to worry about)
cellular response (causes a psychologic change)

Question 3

myocardium M2

Answer 3

decreased contracility, decreased Hr, decreased cv

Question 4

myocardium and conduction system b1

Answer 4

increased contractility, HR, conduction speed

Question 5

describe autonomic innervation of bronchial tree

Answer 5

b2 receptors are not innervated. respond to catecholamines in systemic circulation or in airway

Question 6

what is the autonomic innervation of the kidney

Answer 6

renal tubules- a2 - direusis (ADH inhibition)
renin release - b1- increased

Question 7

autonomic innervation of the eye

Answer 7

radial muscle (iris) a1- contraction- mydriasis

ciliary muscle- b2- relaxation- far vision

Question 8

autonomic of GI tract

Answer 8
