B3
7
Q
Most vascular SM is innervated by
A
Alpha 1
8
Q
No parasympathetic innervation of
A
Vasular SM
9
Q
Vasular SM at rest is mediated by
A
alpha adrenoreceptors
10
Q
Stimulates Epi
A
B2
11
Q
Optometrist gives what to dilate pupils
A
Anti-muscarinic
12
Q
Iris radial muscle
A
contract=dilation
SNS receptor=alpha
13
Q
M3 (eye)
A
stimulates contraction of iris =miosis
This is why anti muscarinic = pupil dilation

A
M2
15

contracts bronchiole smooth muscle
A
M3
