What is a hormone and how does it act? - Answers-
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? - Answers-a secretion that
enters interstitial fluid but affects only neighboring cells
What is an autocrine gland? - Answers-A secretion that
only affects the secreting cell.
What is an endocrine gland? - Answers-A gland that
secretes a substance (a hormone) into the bloodstream
and act on target cells

What is an exocrine gland? - Answers-A ducted gland that
produces a secretion onto a body surface.
Where is the thymus located? - Answers-mediastinum;
behind the sternum
Where is the pineal gland located? - Answers-center of
brain
Where are the reproductive organs located? - Answers-
abdomen; pelvic
Where is the pituitary gland located? - Answers-sella
turcica of the sphenoid bone; base of the brain
Where are the adrenal glands located? - Answers-on top
of each kidney
Where is the pancreas located? - Answers-posterior to the
stomach

What are the two steroid hormones? - Answers-Sex
hormones and adrenal cortex hormones; estrogen and
testosterone
Describe steroid hormones - Answers--diffuse through cell
membranes into cytoplasm or nucleus
-combine with a receptor molecule binding to DNA
-promote transcription of mRNA
-mRNA enters cytoplasm directing protein synthesis
Describe non-steroid hormones. - Answers-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? - Answers-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

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? - Answers-
Hypothalamus
Describe tropic hormones - Answers-stimulate other
endocrine glands to release hormones
anterior pituitary hormones - Answers-ACTH - controls
manufacture and secretion of certain hormones from the
outer layer of the adrenal gland.
FSH - controls growth and development of follicles that
house egg cells in ovaries and stimulate production of
sperm cells in the testes.
GH - stimulates cells to enlarge and more rapidly divide
LH - promotes secretion of sex hormones and allows
release of egg cells from ovaries
PRL - promotes milk production
TSH - controls secretion of certain hormones from the
thyroid
