What is a hormone and how does it act? - - ANS✔️--Hormones are chemical messengers that are
responsible for regulation. They are secreted into body fluids, mainly blood. It has specific
actions on target tissues, which are any tissue that has specific receptors for that particular
hormone.
What is a paracrine gland? - - ANS✔️--a secretion that enters interstitial fluid but affects only
neighboring cells
What is an autocrine gland? - - ANS✔️--A secretion that only affects the secreting cell.
What is an endocrine gland? - - ANS✔️--A gland that secretes a substance (a hormone) into the
bloodstream and act on target cells

What is an exocrine gland? - - ANS✔️--A ducted gland that produces a secretion onto a body
surface.
Where is the thymus located? - - ANS✔️--mediastinum; behind the sternum
Where is the pineal gland located? - - ANS✔️--center of brain
Where are the reproductive organs located? - - ANS✔️--abdomen; pelvic
Where is the pituitary gland located? - - ANS✔️--sella turcica of the sphenoid bone; base of the
brain
Where are the adrenal glands located? - - ANS✔️--on top of each kidney
Where is the pancreas located? - - ANS✔️--posterior to the stomach
What are the two steroid hormones? - - ANS✔️--Sex hormones and adrenal cortex hormones;
estrogen and testosterone
Describe steroid hormones - - ANS✔️---diffuse through cell membranes into cytoplasm or
nucleus
, 3|Page
-combine with a receptor molecule binding to DNA
-promote transcription of mRNA
-mRNA enters cytoplasm directing protein synthesis
Describe non-steroid hormones. - - ANS✔️--Amines, proteins, peptides, and glycoproteins. The
endocrine gland secretes nonsteroid hormones, which body fluid carries hormone to its target
cell. Hormone combines with receptor site on membrane of its target cell, activating G protein.
Cellular changes produce the hormone's effects.
How is the anterior pituitary gland different than the posterior pituitary gland? - - ANS✔️--The
anterior pituitary becomes an endocrine gland producing and secreting hormones for the body
and connects to the posterior pituitary when fully formed. Meanwhile, the posterior pituitary
remains connected to the hypothalamus, functioning as a repository for hormones produced by
the hypothalamus and receiving messages from it that regulate when hormones are to be released
to and through the anterior pituitary
What regulates pituitary gland secretion? - - ANS✔️--Hypothalamus
Describe tropic hormones - - ANS✔️--stimulate other endocrine glands to release hormones
anterior pituitary hormones - - ANS✔️--ACTH - controls manufacture and secretion of certain
hormones from the outer layer of the adrenal gland.
