parathyroid glands
4-6 small endocrine glands on the posterior thyroid that act to increase blood calcium levels
pineal gland
small gland in the brain which secretes melatonin to regulate mood, daily rhythms, sexual development and response to environmental light
anterior pituitary gland
secretes GH and other hormones that affect other glands in the body
posterior pituitary gland
stores and secretes hormones manufactured in the hypothalamus such as antidiuretic hormone & oxytocin
prostaglandins
group of hormones that have various effects including uterine contraction stimulation, blood pressure regulation, blood clotting, and inflammation
receptor
site on a cell membrane which binds a specific substance or hormone
steroid hormone
hormone made from lipids, including those from the gonads and adrenal cortex
target tissue
specific tissue on which a particular hormone acts due to the presence of specialized receptors
thyroid gland
endocrine gland on either side of the larynx and upper trachea which secretes hormones that affect the metabolism, growth, and calcium balance

disease resulting from deficiency of adrenocortical hormones marked by darkening of the skin, weakness, and water loss and electrolyte imbalance
adenoma
neoplasm of a gland
congenital hypothyroidism
condition caused by congenital lack of thyroid secretion which halts physical and mental development in infants
Cushing’s disease
excess production of adrenocorticotropic hormone by the pituitary gland causing overproduction of cortisol by the adrenal cortex, which results in fluid retention, hypertension, obesity of the torso, weakness, excess hair growth, and a moon-shaped face

overgrowth of a child caused by excess growth hormone release by the pituitary gland

hyperglycemia
excess glucose in the blood
hypoglycemia
abnormally low levels of glucose in the blood
