Chapter 9 - The Endocrine System Flashcards
A gland on the superior surface of the kidney.
adrenal gland
Pertaining to a ductless gland that secretes hormones into the blood
endocrine
A secretion of an endocrine gland. A substance that travels in the blood and has a regulatory effect on tissues, organs, or glands
hormone
The pituitary gland (root: hypophys); named from hypo, meaning “below,” and physis, meaning “growing,” because the gland grows below the hypothalamus
hypophysis
A portion of the brain that controls the pituitary gland and is active in maintaining homeostasis
hypothalamus
Cluster of endocrine cells in the pancreas that secretes hormones to regulate glucose metabolism
pancreatic islet
A small endocrine gland on the posterior thyroid that acts to increase blood calcium levels
parathyroid gland
A small gland in the brain. Appears to regulate mood, daily rhythms, and sexual development in response to environmental light
pineal gland
A small endocrine gland at the base of the brain. The anterior lobe secretes growth hormone and hormones that stimulate other glands
pituitary gland
A group of hormones produced throughout the body that have a variety of effects, including stimulation of uterine contractions and regulation of blood pressure, blood clotting, and inflammation
prostaglandins
A hormone made from lipids and including the sex hormones and the hormones of the adrenal cortex
steroid hormone
A site on the cell membrane or within the cell to which a substance, such as a hormone, attaches
receptor
The specific tissue on which a hormone acts; may also be called the target organ
target tissue
An endocrine gland on either side of the larynx and upper trachea. It secretes hormones that affect metabolism and growth (roots: thyr/o, thyroid/o).
