ACTH RF or CRF target

Anterior Pituitary

ACTH RF or CRF Effect

Release ACTH

GnRh Target

Anterior pituitary

GnRh effect

Release of Lh or FSH

TSH RF or TRH target

Anterior Pituirary

TSH RF or TRH effect

Release TSH

ADH Target

Kidneys and blood vessels

ADH effect

helps to control blood pressure by causing reabsorption of water into the blood from the kidneys and constriction of blood vessels

oxytocin target

Uterus and Breasts

Oxytocin Effect

causes contractions for birth and release of milk during breastfeeding

hGH (GH for non humans)

Targerts most cells (bones and muscles)

hGH (GH) effect

promotes growth (proteins)

TSH target

Thyroid Gland

TSH effect

stimulates thyroid gland to release thyroxin, which increases metabolism

ACTH Target

Adrenal Cortex

ACTH effect

Stimulates the release of aldosterone and cortisol

FSH target

Ovaries and Testes

FSH effect

Stimulates production of eggs and estrogen in Overies.
stimulates sperm production in testes

LH Target

Ovaries and Testes

LH effect

Stimulates Ovulation (Release of egg) and progesterone and estrogen production in females
Stimulates testoterone production in males

PRL target

mammary glands

PRL effect

Production of breast milk

Thyroxine target

all body cells

Thyroxine effect

increase metabolic rate

calcitonin target

Bones, Kidney and small intestines

Calcitonin effect

Stores calcium in bones, decreases calcium in blood

PTH Target

Bones, Kidney and small intestines

PTH effect

Removes calcium form bones, increases blood calcium levels

Aldosterone target

Kidney

Aldosterone effect

Increases sodium reabsorption into the blood and water follows due to osmosis which increases blood pressure

Cortisol Target

Liver and Muscles

Cortisol effect

Increases levels of amino acids in blood to help body recover from stress. Liver converts Amino acids into glucose wchi is released into blood for more energy.

Epinepharine (Adrenaline) target

Heart, Blood vessels, Liver

Epinephrine effect

Increases heart rate and blood pressure, blood flow to the muscles and blood glucose (fight or flight response)

Insulin target

Liver, Muscles, all cells

Insulin effect

Lowers blood sugar, stores glucose as glycogen, allows glucose to enter cells

Glucagon Target

Liver

Glucaton Effect

Raises blood sugar, converts glycogen to glucose

Testosterone target

Sertoli cells inside the seminiferous tubules

Testosterone effect

Sperm production, Primary and secondary sex characteristics

Estrogen target

Various cells

Estrogen effect

secondary sex characteristics and Growth of Endometrium

Progesterone target

Mammary glands and Endometrium (Uterine lining)

Progesterone effect

Growth and Maintenace of Endometrium, Inhibits ovulation and prevents contractions

What type of hormones does the pituitary gland Release

Tropic hormones

Tropic hormones

Target endocirne glands and cause the release of their hormone

Hypersecretion of ADH causes

Abnormal water retention

Hyposecretion of ADH causes

Increase of urination, Dehydration, low blood pressure

Hyposecretion of Oxytocin causes

Prolonged or difficult birth

Hypersecretion of oxytocin causes

inappropriate ejection of milk

Hypersecretion of thyroxin (hyperthryoridism) causes

High metabolic rate, can’t sit still, always warm, and weight loss

Hypo secretion of thyroxin (hypothyroidism) causes

Low metabolic rate, less active, intolerant of cold, dry skin and gain weight, goitre

Hyposecretion of cortisol causes

Fatigue

Hypersecretion of cortisol causes

High blood glucose

Hyposecretion of Aldosterone causes

Water loss or low blood pressure

Hypersecretion of aldosterone causes

Increased water retention
