Final answer:
Stimulation of alpha-1 adrenergic receptors generally results in smooth muscle contraction and, in some cases, dilation. Hence the correct answer is option A
Step-by-step explanation:
True
Stimulation of alpha-1 adrenergic receptors generally results in contraction of smooth muscle, which can lead to dilation.
Alpha-1 adrenergic receptors are a type of adrenergic receptor that, when activated, cause an increase in intracellular calcium and subsequent smooth muscle contraction. This can occur in various smooth muscles throughout the body, including blood vessels, gastrointestinal tract, and urinary system.
