Receptors

Question 1

What are the 3 locations of cholinergic receptors in the eye?

Answer 1

Iris sphincter
Ciliary muscle
Lacrimal gland

Question 2

What is the 1 location of alpha 1 receptors in the eye?

Answer 2

Iris dilator

Question 3

What are the 3 locations of beta 2 receptors in the eye?

Answer 3

TM
Ciliary muscle
NPCE

Question 4

What is the structure in the eye with both beta 1 and beta 2 receptors?

Answer 4

NPCE

Question 5

What is the 1 location of alpha 2 receptors in the eye?

Answer 5

Ciliary Body vasculature

Question 6

When the cholinergic receptors of the ciliary muscle are stimulated, what occurs?

Answer 6

Accommodation

Question 7

When alpha 1 receptors in the eye are stimulated, what occurs?

Answer 7

Dilation (located on iris dilator)

Question 8

When beta 2 receptors in the eye are stimulated, what occurs?

Answer 8

TM relaxes - outflow increases
Ciliary muscle relaxes - opposes accommodation
Aqueous formation increases (NPCE)

Question 9

When alpha 2 receptors in the eye are stimulated, what occurs?

Answer 9

Vascular constriction (CB) - reduces aqueous formation
