Endocrine System
Hormones
-
Follicle-stimulating hormone(FSH): -Targets ovaries and testes
-Function females stimulates ovulation and stimulates ovarian production of estrogen and progesterone
-Function males increases stimulates sperm production
Adrenocorticotropic Hormone(ACTH): -Targets adrenal gland
-Promotes release of glucocorticoids and androgen
Luteinizing Hormone(LH): -Targets ovaries and testes
-Function females stimulates ovulation and stimulates ovarian production of estrogen and progesterone
-Function males increases stimulates sperm production
Thyroid stimulating hormone(TSH): -Targets the thyroid gland
-Function is stimulates thyroid gland to regulate hormones of the thyroid
Antidiuretic Hormone(ADH): -Targets kidneys
-Function is to stimulate kidney tubule cells to reabsorb water from the forming urine back into blood
-In Posterior Pituitary
Oxytocin: -Targets uterus and breast
-Function stimulates uterine contractions
-Functions initiates labor
-Initiates milk ejection
-Posterior Pituitary
Growth Hormone(GH): -Targets the liver,muscle,bone,cartilage and other tissues
-The functions is to stimulate somatic groweth,mobilizes fats, sparse glucose
-The function is growth promoting effects mediated indirectly by IGF's

The hormones are involved in reproduction,growth and development, maintenance water electrolyte, water and nutrient balance of blood, regulation of cellular metabolism and energy balance and mobilization of body defenses
Pituitary
Thyroid stimulating hormone(TSH): -Targets the thyroid
-Stimulates thyroid gland to release thyroid hormones
Adrenoncorticotropic hormone(ACTH): -Targets adrenal cortex
-Promotes release of glucocorticolds and androgens
Follicle stimulating hormone(FSH) /Luteinizing hormone(LH): -Targets the testes and the ovaries
-in females it triggers ovulation and stimulates ovarian production of estrogen and progesterone
-In males stimulates sperm production
-
Growth Hormone(GH): -stimulates somatic growth
-mobilizes fats
-spares glucose
-Targets the bones and muscles
Adrenal Cortex
Cortisol: -Targets body cells
-help body adapt to food intake and help maintain blood pressure
-influences the energy metabolism of most body cells and help resist stress
Aldosterone: -Targets kidney
-Principal regulates of salt and water balance has small effects in the metabolism of fats,carbohydrates, and proteins
-balance sodium and potassium in body
Thyroid Gland
Thyroid Hormone(TH): -increases basal metabolic rate and body heat production
-Regulating tissue growth and development. It is critical for skeletal and nervous system development and maturation and for reproductive system
-Maintaining blood pressure by inc. the number of adrenergic receptors in blood vessels
-Target every cell in the cell
Calcitonin: -Target the bones
-Does not have a known physiological role
-has bone sparing effect
-stimulates calcium uptake and incorporation
targets where it inhibits osteoclast activity
Adrenal Medulla
Epinephrine: -Targets heart,lungs,and kidney
-increases heart rate and force contraction
-stimulates kidneys to regulate
-relaxes uterus
-dilates pupils of the eyes
Parathyroid gland
Parathyroid hormone(PTH): -Targets skeleton, kidneys, intestine
-stimulates osteoclast to digest some Ca rich bone marrow
enhances the kidneys reabsorbtion of calcium from urine to blood
-promotes activation of vitamin D
