KIN 170 Endocrine Assignment ENDOCRINE GLAND

LOCATION IN BODY

HORMONE SECRETED

BASIC ROLE OF HORMONE

HYPOTHALAMUS

Brain

1. ADH 2. oxytocin 3. regulatory hormones

1. concentration of water in urine 2. uterine contractions, mammary 3. releasing hormones or inhibiting hormones

*posterior pituitary*

Anterior-sits 1. TSH – thyroid stimulating hormone in sella tursica cavity 2. adrenocorticotropic hormone (ACTH) Infundibulum 3. FSH divides 4. Luteinizing hormone anterior to 5. prolactin (PRL) 6. growth hormone posterior (GH) 7. melanocytestimulating hormone (MSH)

1. triggers release of thyroid hormones 2. stimulates glucocorticoid release from adrenal gland 3. estrogen secretion and oocyte and sperm development 4. ovulation, progesterone and testosterone 5. development of mammaries and milk production 6. skeletal muscle and bone growth and cell replication/growth 7. melanocytes to produce melanin (only birth, young and pregnant)

Posterior**

1. ADH and Oxytocin

AS ABOVE UNDER HYPOTHALAMUS

PINEAL

Epithalamus

Melatonin

Helps to establish circadian rhythms Also, may affect timing of puberty (antigonadotrophic effect)

THYROID

Inferior to larynx

1. thyroxine (T4) 2. triiodothyronine (T3) 3. calcitonin

1. metabolism 2. metabolism 3. lowers blood calcium

PARATHYROID

Posterior thyroid (4)

Parathyroid hormone (by chief cells)

1. increases blood magnesium levels

THYMUS

Mediastinum Thymosins - Posterior sternum

PITUITARY

calcium

and

Immunological defence (decreases with age) Promote development and maturation of lymphocytes

PANCREAS

ADRENALS

Stomach – duodenal region

Superior to kidney

1. glucagons

1. increase blood glucose levels

2. insulin

2. lowers blood glucose by increasing glucose uptake

3. somatostatin

3. inhibits secretion of insulin and glucagon and slows absorption of nutrients in the GI tract

4. pancreatic polypeptide

4. inhibits somatostatin, gallbladder contraction and secretion of pancreatic digestive enzymes

1. medulla: epinephrine & norepinephrine

1. sympathetic chain ganglion – E and NE involved in fight-or-flight response; cellular energy utilization and mobilization of energy reserves

2. cortex: a. mineralocorticoid (aldosterone) b. glucocorticoid (cortisol) c. gonadocorticoid (androgen)

TESTES

Male scrotum

Testosterone

a. electrolyte (NA+> & K+...
