Question

Which adrenoreceptors are found in the eyes, arterial smooth muscle, and most sympathetic targets?

a) A1 receptors
b) A2 receptors
c) Beta-1 receptors
d) Beta-2 receptors

Answer 1

Beta-2 receptors are found in the eyes, arterial smooth muscle, and most sympathetic targets.

Step-by-step explanation:

The adrenergic system consists of two main groups of receptors: alpha (a) and beta (ß) adrenergic receptors. These receptors are found in various tissues, including the eyes, arterial smooth muscle, and most sympathetic targets.

In the given options, the adrenoreceptors that are found in the eyes, arterial smooth muscle, and most sympathetic targets are beta-2 receptors (d). Beta-2 receptors are primarily responsible for dilation of the pupils and relaxation of arterial smooth muscle.
