Endocrine Hormones

Front 1

Thyroid-Stimulating Hormone (TSH)

Back 1

It stimulates the thyroid gland, and promotes the release of normal levels of thyroid hormones.

Front 2

Adrenocorticotropic Hormone (ACTH)

Back 2

It stimulates the adrenal cortex to release steroid hormones, specifically the release of glucocorticoids.

Front 3

Gonadotropins
(FSH)

Back 3

FSH in stimulates follicle development and estrogen secretion in females.

FSH stimulates sperm cell production in males.

Front 4

Gonadotropins
(LH)

Back 4

LH stimulates ovulation and progestin production in females.

LH stimulates androgen production in males.

Front 5

Prolactin
(PRL)

Back 5

Stimulates milk production by the breast, and mammary gland development in females. It is believed to help regulate androgen production in males.

Front 6

Growh Hormone (GH) or Somatotropin

Back 6

It stimulates cell growth and replication in body tissues, especially in skeletal muscle, cartilage, and bone tissues.

This effect is produced by somatomedins produced by the liver.

GH also mobilizes stored fat, stimulates protein synthesis, and stimulates the glucose-sparing effect by inhibiting glucose uptake and metabolism.

Front 7

Melanocyte Stimulating Hormone
(MSH)

Back 7

Stimulates production of melanin by melanocytes in the skin.

Front 8

Antidiuretic Hormone (ADH)

Back 8

Stimulates the decrease of urine output by water conservation, and in high concentration raises blood preessure by vasoconstriction.

Front 9

Oxytocin

Back 9

It stimulates strong utering contractions that trigger labor, it causes milk ejection during lactation, and also seems to promote sexual arousal and nurturing behavior.

Front 10

Thyroid Hormones

Back 10

T4 and T3 which are secreted by the folllicular cells which manufacture them from the amino acid tyrosine.

They increase rates of oxygen uptake, basal metabolic rate, & help maintain body temp.

They help regulate growth, development, and intracellular metabolism by increasing protein synthesis and lipid breakdown.

Front 11

Calcitonin

Back 11

Produced by parafollicular (C) cells in the thyroid gland in response to high levels of calcium in the blood.

It lowers blood calcium by the inhibition of osteoclasts, which slows the rate of calcium ion release from bone.

And by stimulation of calcium ion excretion at the kidneys.

Front 12

Parathyroid Hormone
(PTH)

Back 12

It increases calcium blood levels by increasing formation and secretion of calcitriol.

Also it increases the activity of osteoclasts, which release calcium into blood and inhibits osteoblasts' rate of calcium deposition in bone.

Front 13

Mineralocorticoids

Back 13

Primarily aldosterone, which increases sodium ion and water reabsorption, and potassium secretion by kidneys.

High plasma potassium and low plasma sodium stimulate sectetion of aldosterone.

Front 14

Glucocorticoids

Back 14

These include cortisol (95%), coticosterone, and cortisone.

They help the body to resist stressors by promoting protein and triglyceride breakdown, and increaseing glucose formation.

Front 15

Catecholamines

Back 15

Epinephrine and Norepinephrine

Increase cardiac activity, blood pressure, glycogen breakdown, blood glucose levels, & triglyceride breakdown.
