A) it is a source of catecholamines.
B) it is considered a modified sympathetic ganglion.
C) it releases epinephrine and norepinephrine directly into the blood.
D) it is a source of catecholamines and it is considered a modified sympathetic ganglion.
E) it is a source of catecholamines, it is considered a modified sympathetic ganglion, and it releases epinephrine and norepinephrine directly into the blood.

Answer 1

A) it is a source of catecholamines.

The adrenal medulla is important to the sympathetic branch of the autonomic nervous system because it is a source of catecholamines, it is considered a modified sympathetic ganglion, and it releases epinephrine and norepinephrine directly into the blood.

Step-by-step explanation:

The adrenal medulla is important to the sympathetic branch of the autonomic nervous system because it is a source of catecholamines (epinephrine and norepinephrine), it is considered a modified sympathetic ganglion, and it releases epinephrine and norepinephrine directly into the blood. The adrenal medulla is a neuroendocrine tissue composed of postganglionic sympathetic nervous system neurons. It is stimulated by impulses from the hypothalamus and releases the stress hormones epinephrine and norepinephrine into the bloodstream.
