general receptors Flashcards
1
Q
B1 adrenoreceptor
A
Gs
- increase CO
- increase renin secretion
2
Q
B2 adrenoreceptor
A
gs
- smooth muscle relaxation
- β2 adrenergic agonists’ effects on smooth muscle cause dilation of bronchial passages, vasodilation in muscle and liver, relaxation of uterine muscle, and release of insulin. They are primarily used to treat asthma and other pulmonary disorders, such as COPD.
3
Q
thytroptin receptor
A
Gs
- TSH binds
- iodine pumping and T3/T4 release
4
Q
glucagon receptor
A
Gs
- causes breakdown of glycogen when adrenaline binds- increase blood glucose
5
Q
B3
A
Gs
- adipose tissue
- lipolysis
6
Q
gene expression
A
Gs
-PKA phosphorylates DNA binding elements
7
Q
M2 muscarinic Ach
A
Gi
- decreased cardiac output
- decreasing BP
8
Q
alpha2
A
- vasoconsriction of blood vessels
- autonomic NS
- inhibition of NA, ACH and insulin released
9
Q
opiod receptors
A
Galphai
10
Q
M1 (muscarinic Ach)
A
Gq
- CNS excitation
- gastric acid secretion
11
Q
M3 (muscarininc Ach)
A
Gq
- secretion of gland
- smooth muscle contraction
- vasodiltion via NO
12
Q
M5
A
Gq
memory, arousal and attention
13
Q
alpha1
A
Gq
- vasoconstriction
- increase BP
14
Q
Angiotensin II (AT1)
A
Gq
15
Q
vasopressin 1
A
Gq
