Endocrine Glands (1st half)

Endocrine Glands, what hormone they release, chemical class, target tissue/organ, regulated by, and major function

Hypothalamus

Releases: hypothalamic releasing & inhibiting hormones Chemical: Peptide Target: Anterior Pituitary Regulated by: none Function: regulates anterior pituitary hormone

Posterior Pituitary

Releases: Antidiuretic (ADH) Chemical: Peptide Target: Kidneys Regulated by: Water/Salt Balance Function: Stimulates water reabsorption - regulate water balance

Posterior Pituitary

Releases: Oxytocin (OT) Chemical: Peptide Target: Uterus, mammary glands Regulated by: Nervous System (hypothalamus) Function: Stimules uterine muscle contractions and release of milk by mammary glands

Anterior Pituitary

Releases: Thyroid Stimulating Hormone (TSH) Chemical: Protein Target: Thyroid Regulated by: Thyroxine in blood, Hypothalamus (TRH) Function: Stimulates thyroid hormone secretions to secrete glucocorticoids

Anterior Pituitary

Releases: Adrenocorticotropic (ACTH) Chemical: Protein Target: Adrenal Cortex Regulated by: Hypothalamus (CRH) Function: Stimulates the Adrenal Cortex (Cortisol)

Anterior Pituitary

Releases: Follicle Stimulating Hormone (FSH) aka: Gonadotropins Chemical: Protein Target: Gonads Regulated by: Hypothalamus Function: Egg (ova) and sperm production

Anterior Pituitary

Releases: Luteinizing Hormone (LH) aka: Gonadotropins Chemical:Protein Target: Gonads Regulated by: Hypothalamus Function: Stimulates ovaries & tests for sex hormone production (estrogen/testes)

Anterior Pituitary

Releases: Prolactin (PRL) Chemical: Protein Target: Mammary Glands Regulated by: Hypothalamus Function: Milk Production

Anterior Pituitary

Releases: Growth Hormone Chemical:Protein Target: Soft tissue/bones Regulated by:Hypothalamus- GH releasing and inhibiting Function:stimulates growth (cell division), metabolism, bone, and muscle growth

Anterior Pituitary

Released:Melanocyte-Stimulating Hormone (MHS) Chemical:Peptide Target: Skin-melanocytes Regulated by: None Function: Stimulates production of melanin pigment

Thyroid

Releases:Thyroxine and Triiodothyronine Chemical: Amine Target: All tissue Regulated by: TSH Function: Increase metabolic rate, regulates growth and development

Thyroid

Releases: Calcitonin Chemical: Peptide Target: bones, kidneys, intestines Regulated by: Calcium ion levels in blood Function:Lowers blood calcium levels
