Health Science I: 4.02 Endocrine System Hormones and Structures

Growth Hormone (GH)

released from Anterior pituitary; stimulates growth and cell reproduction

adrenocorticotroic hormone (ACTH)

released from Anterior pituitiary; stimulates adrenal glands to release cortisol

Thyroid stimulating hormone (TSH)

released from Anterior pituitary: stimulates thyroid to release T3 and T4

Luteinizing hormone (LH)

released from Anterior pituitary: surges right before ovulation

Follicle stimulating hormone (FSH)

relased from anterior pituitary: stimulates female follicles to start to mature

prolactin

released by Anterior pituitary: stimulates breast development and milk production

oxytocin

stimulates contractions during L&D; helps uterus regain its shape

anti-diuretic hormone (ADH)

released from posterior pituitary, causes retention of water

thyroxin

produced by the thyroid aka T4, regulates metabolism

Parathormone

secreted by the parathyroid gland; works to regulate calcium in the bloodstream, prevents hypocalcemia

glucocorticoids

released by adrenal cortex; regulates the emission of stored glucose into the blood

mineralcorticoids

produced by the adrenal cortex; regulates levels of electrolytes, salt and water

epinephrine / Adrenalin

produced by the adrenal medulla, ignores raises HR and RR, dilates bronchiles, fight/flight

norepinephrine

works with adrenalin, raises BP, released by adrenal medulla

insulin

released by the pancreas, regulates glucose in the bloodstream

progesterone and estrogen

released by the ovaries, responsible for female sex characteristics and reproduction

testosterone

released by the testes, responsible for male sex characteristics and reproduction

hormone

chemical messenger; changes something

endocrine system

integrated system of small organs that release hormones

ductless glands

endocrine glands are ____ b/c they release hormones directly into the bloodstream

hypothalamus

the master of the "master gland"; controls pituitary gland

pituitary gland

"master" gland; influences all the body's activities' located in the base of brain below the hypothalamus, has anterior and posterior lobe

thyroid

butterfly-shaped organ with 2 lobes on each side of the trachea

thymus

located behind the sternum; bi-lobed; gradually shrinks as age increases

pancreas

located behind the stomach, large gourd shaped organ

adrenal glands

the snow caps atop of the kidneys; has a medulla and cortex

testes and ovaries

primary reproductive organs

Parathyroid gland

4 small glands in embedded in the thyroid gland
