Term | Definition |
---|---|
endocrine system | made up of organs and glands that produce, store, and release hormones. |
hormones | are chemicals used by the body to increase or decrease activity of the hormone's specific target cells. this aids the body in homeostasis. |
exocrine glands | release hormones into a duct for delivery to the target cells. |
endocrine glands | release hormones directly into the blood stream |
Adrenal glands/ Cortex: aldosterone | hormone that regulates electrolytes and fluid volume |
Adrenal glands/ Cortex: cortisol | hormone that regulates carbohydrates |
Adrenal Glands/ Medulla: epinephrine | hormone that is the fight-or-flight response. |
Adrenal glands/ Medulla: norepinephrine | vasoconstrictor (narrowing of blood vessels) |
hypothalamus/ Produces: antidiuretic hormone | stimulates reabsorption of water in the kidneys |
Hypothalamus/ Produces: oxytocin | stimulates uterine contractions during labor and release of breast milk |
Ovaries/ Estrogen | development of secondary sex characteristics in females, regulates menses |
Ovaries/ Progesterone | Prepares the body for pregnancy |
Pancreas/ Alpha cells: glucagon | increases blood sugar |
Pancreas/ Beta cells: insulin | deceases blood sugar |
Parathyroid gland/ Parathyroid hormone | regulates calcium |
Pineal gland/ melatonin | regulates onset of puberty, biological clock |
Pituitary gland anterior/ Growth hormone | stimulates body growth |
Pituitary gland anterior/ melanocyte-stimulating hormone | stimulates skin pigment |
Pituitary gland anterior/Adrenocorticotropic hormone | regulates adrenal cortex |
Pituitary gland anterior/ Thyroid-stimulating hormone | regulates thyroid gland |
Pituitary gland anterior/ Follicle-stimulating hormone | stimulates growth of ova and sperm |
Pituitary gland anterior/ luteinizing hormone and prolactin | stimulates ovulation (females) and testosterone production (males) |
Pituitary gland, posterior/ Releases: Antidiuretic hormone | stimulates reabsorption of water by the kidneys |
Pituitary gland, posterior/ Releases: oxytocin | stimulates uterine contractions during labor and release of breast milk |
testes/ testosterone | sperm production, secondary sex characteristics in males |
thymus/ T3 and T4 | cellular metabolism |
thyroid gland/ calcitonin | increases bone calcium |
