Question

question 3
which endocrine organ consists of sympathetic ganglia?
a adrenal cortex
b adrenal medulla
c ovary
d parathyroid
e thyroid

Explanation:

The adrenal medulla is derived from neural crest cells, which are related to sympathetic ganglia. It secretes hormones like epinephrine and norepinephrine in response to sympathetic nervous system activation. The adrenal cortex (A) is involved in steroid - hormone production (e.g., cortisol, aldosterone) and has no relation to sympathetic ganglia. The ovary (C) produces estrogen and progesterone (female sex hormones). The parathyroid (D) is involved in calcium - phosphate homeostasis (produces parathyroid hormone). The thyroid (E) produces thyroid hormones (e.g., thyroxine) which are involved in metabolism regulation.

Answer:

B. adrenal medulla
