Chapter 16 - The Endocrine System Flashcards
DM
Diabetes mellitus
FBS
Fasting blood sugar
GH
Growth hormone
TSH
Thyroid-stimulating hormone
Gland on superior surface of kidney. Outer region (cortex) secretes steroid hormones. Inner region (medulla) secretes epinephrine (adrenaline) and norepinephrine (noradrenaline)
Adrenal gland
Pertaining to ductless gland that secretes directly into the blood
Endocrine
A secretion from an endocrine gland. A substance that travels in the blood and has a regulatory effect on tissues, organs, glands
Hormone
The pituitary gland, grows below the hypothalamus
Hypophysis
Portion of brain that controls the pituitary gland and is active in maintaining homeostasis
Hypothalamus
Clusters of endocrine cells in pancreas that secrete hormones to regulate sugar metabolism. Islets of langerhans. Islet cells
Pancreatic islets
Small endocrine glands on the posterior thyroid that act to increase blood calcium levels.usually four to six of them.
Parathyroid glands
Small gland in the brain. Regulate mood, daily rhythms, sexual development in response to environmental light. Secrete hormone melatonin.
Pineal gland
Small endocrine gland at the base of brain.
Anterior lobe secretes growth hormone and hormones that stimulate other glands.
Posterior lobe releases ADH and oxytocin manufactured in the hypothalamus
Pituitary gland
Group of hormones produced throughout the body that have a variety of effects, include stimulation of uterine contractions, regulate blood pressure, blood clotting, inflammation
Prostaglandins
Site of cell membrane or within cell to which a substance such as a hormone attaches
Receptor
Hormone made from lipids and including the sex hormones and the hormones of the adrenal cortex
Steroid hormone
Specific tissue on which a hormone acts. Target organ
Target tissue
Endocrine gland on either side of larynx and upper trachea. Secretes hormone that affects metabolism and growth and a hormone (calcitonin) that regulates calcium balance
Thyroid gland
endocrin/o
Endocrine glands or system
