SOME ENDOCRINE GLANDS

Slide 2

Pineal Gland

Synthesizes Melatonin responsible for biological clock

Slide 3

Thyroid Gland

For metabolism Thyroxine (T4) Triiothyronine (T3) Calcitonin

Slide 4

Parathyroid Gland

Behind thyroid gland Generally found as 4 glands Secretes parathyroid hormone Essential for calcium and phosphate regulation

Slide 5

Thymus

Inferior to thyroid gland Undergoes atrophy during adulthood Secretes thymosine

Slide 6

Heart

Secretes the hormone: Naturetic Peptide Decreases blood pressure

Slide 7

Digestive Tract

Produces many hormones: Gastrin, Secretin Somatostatin, CKK, GIP, VIP, etc.

Slide 8

Pancreas

Insulin to decrease blood pressure Glucagon to increase blood pressure

Diabetes Type I: depleted insulin levels Type II: low insulin levels High glucose levels

Slide 9

Kidneys

Erythropoietin for RBC production in bone marrow Calcitriol

Slide 10

Adrenal Glands

Adrenal Cortex Outer part Cortisol for stress Aldosterone for sodium reabsorption and potassium secretion in kidneys

Adrenal Medulla Middle part Adrenaline (epinephrine) Noradrenaline (norepinephrine) For fight-flight response

Slide 11

Adipose Tissue

Secretes leptin Important for fat metobolism

Slide 12

Gonads

Testis Androgens - testosterone Promotes male characteristics & sperm production

Ovaries Estrogen & Progestrone Female characteristics & egg production
