Where are the alpha-1 receptors located? What is their effect? ----
ANSWER----location-blood vessels
constricted blood vessels, skin is pale, cool, clammy

,They essentially increase BP
Where are the Beta-1 receptors located? What is their effect? ----
ANSWER----location-heart
effect- increased HR, increased force of contraction
They essentially increase CO since CO = HR x SV
Where are the Beta-2 receptors located? What is their effect? ----
ANSWER----location - lungs (beta-2 is beta-tube)
effect - bronchodilation (more air enters lungs)
Where are the muscarinic receptors located? What is their effect? ----
ANSWER----location - heart
Page 3 of 58
, effect - decreased HR, decreased force of contraction
Muscarinic is parasympathetic system and do complete opposite of
Beta-1 which is sympathetic
What hormones activate the sympathetic nervous system? ----
ANSWER----Epineprhine and norepineprhine, which are released
from he adrenal gland after stimulation by the sympathetic nervous
system. These hormones stimulate heart and blood vessels.

pleura lines the lungs. The space between is called the anterior pleura.
---- ANSWER----False: the visceral pleura lines the lungs, the parietal
pleura lines the body cavity and the pleural space is the space in
between both where body fluid allows for both to smoothly glide.
