Flashcards in Chapter 16 - The Endocrine System Deck (59)
Made from lipids. Created in the gonads and the outer region of the adrenal glands
Growth hormone (GH)
Promotes growth of all tissue. Also called somatotropin
Thyroid stimulating hormone (TSH)
Stimulates thyroid gland to produce thyroid hormones
Stimulates adrenal cortex to produce cortical hormones. Aids in protecting the body in stress situations.
Follicle stimulating hormone (FSH)
Stimulates growth and hormonal activity of ovarian follicles. Stimulates growth of testes. Promotes sperm cell development.
Luteinizing hormones (LH)
Causes development of corpus luteum at site of ruptured ovarian follicle in female; stimulates testosterone secretion in males.
Stimulates milk secretion in mammary glands.
Antidiuretic hormone (ADH)
Promotes water reabsorption is kidney tubules; causes blood vessels to constrict
Causes uterine contractions; causes milk ejection from mammary glands
Thyroxine; tetraiodothryonine (T4) triiodothyronine(T3)
Increases metabolic rate and heat production; influencing both physical and mental activities; required for normal growth
Parathyroid hormone (PTH)
Regulates calcium exchange between blood and bones; increases blood calcium levels.
Aids in metabolism of carbohydrates, proteins, and fats. Active during stress
Aids in regulating electrolytes and water balance
May influence secondary sexual characteristics
Aids in glucose transport into cells; required for cellular metabolism of nutrients; especially glucose. Decreases blood glucose levels.
Stimulates liver to release glucose thereby increasing glucose levels.
Regulates mood, sexual development and daily cycles in response to environmental light
Stimulates growth and development of sexual organs plus development of secondary sexual characteristics. Stimulates maturation of sperm cells.
Stimulates growth of primary sexual organs and development of secondary sexual characteristics.
Prepares uterine lining for implantation of fertilized ovum; aids in maintaining pregnancy; stimulates development of mammary glands secretory tissue
Pituitary gland (hypophysis)
Small gland beneath the brain. Divided into anterior (adenohyphosis) and posterior lobe (neurohyphosis)
Part of the brain that regulates homeostasis. Controls both lobes of the pituitary gland.
Produces 6 hormones including growth hormone. Remainder regulate other glands
Releases 2 hormones that are actually made in the hypothalamus. Antidiuretic hormone and oxytocin.
Consists of two lobes on either side of the larynx and upper trachea. Connected by narrow band called an isthmus. Secretes a mixture of hormones. (T4, T3)
Thyroid binding globulin. Binds thyroid hormones in blood to proteins.
On posterior surface of the thyroid. Affects calcium metabolism.
Located above the kidneys. Divided into two distinct regions. Outer cortex and inner medulla.
Produces steroid hormones. Cortisol, aldosterone, sex hormones
