Which endocrine gland secretes epinephrine (adrenaline) into the bloodstream?
A
Adrenal medulla (inner region of the adrenal gland)
B
Anterior pituitary (adenohypophysis)
C
Thyroid gland (follicular cells)
D
Pancreatic islets (beta cells)
Verified step by step guidance1
Understand that epinephrine, also known as adrenaline, is a hormone involved in the body's fight-or-flight response, which prepares the body to respond to stress.
Recall that the adrenal gland is divided into two main parts: the adrenal cortex (outer region) and the adrenal medulla (inner region). Each part secretes different hormones.
Identify that the adrenal medulla is responsible for secreting catecholamines, which include epinephrine and norepinephrine, directly into the bloodstream.
Recognize that the anterior pituitary secretes different hormones such as growth hormone and ACTH, but not epinephrine.
Note that the thyroid gland produces thyroid hormones (like thyroxine) and the pancreatic islets (beta cells) secrete insulin, neither of which are epinephrine.
