Question

the adrenal medulla can be involved in playing a supplementary to _______.

○ parasympathetic innervation

○ sympathetic stimulation

○ vagus (x) nerve activity

○ somatic stimulation

question 2 0.75 pts

all of the following describes ans except?

○ a system of motor neurons that innervates smooth and cardiac muscle and glands

○ a system of motor neurons that innervates all muscle cells

○ involuntary nervous system

○ general visceral motor system

Explanation:

First Question (Adrenal Medulla)

The adrenal medulla is part of the sympathetic nervous system. It secretes hormones (like epinephrine) that supplement sympathetic stimulation during the "fight - or - flight" response. Parasympathetic innervation (including vagus nerve activity) is the opposite of sympathetic, and somatic stimulation is related to voluntary muscle control, so they don't match.

The Autonomic Nervous System (ANS) innervates smooth muscle, cardiac muscle, and glands (involuntary structures). It's also called the involuntary nervous system or general visceral motor system. Somatic motor neurons innervate skeletal (voluntary) muscle cells. So the option saying "A system of motor neurons that innervates all muscle cells" is incorrect as ANS doesn't innervate skeletal muscle (which is part of "all muscle cells").

Answer:

B. sympathetic stimulation
