Part of Endocrine and Exocrine
Small clusters of cells that make up the Pancreas
Acini produce
Digestive Enzymes
Endocrine tissue scattered among the acini
Pancreatic Islets / Islets of Langerhans
Pancreatic Islet Cell Types
Alpha (A), Beta (B), Delta (D), and F cells
Alpha cells secrete? and Function
Glucagon, raises blood glucose level
Beta Cells secrete? and Function
Insulin, lowers blood glucose level
Delta cells secrete? and Function
Somatostatin, inhibits insulin and glocagon release from alpha and beta cells. Also acts as a circulating hormone to slow absorption of nutrients from GI tract
F Cells secrete? and Function
Pancreatic Polypeptide, inhibits somatostatin secretion, gallblader contraction, and secretion of digestive enzymes by the pancreas
Glucagon acts on
The liver
Hormones produced by the ovaries
Estrogen and Progesterone, Inhhibin and Relaxin
Protein hormone that inhibits secretion of follicle stimulating hormone, produced by the ovaries
Peptide hormone which increases the flexibility of the pubic symphysis during pregnancy and helps dialate the uterine cervix during labor and delivery
Name for male sex hormone
Small endocrine gland attached to the roof of hte third ventricle of the brain at the midline
Pineal Gland
Capsule that covers the pineal gland, conisists of masses of neuroglia and secretory cells
Hormone secreted by the Pineal Gland, derived from serotonin. Released during darkness. Helps set biological clock
Hormones of Thymus promote?
Maturation of T cells, and retards aging process
Two types of Eicosanoids, act as local hormones in most tissues of hte body
Prostaglandins (PG's) and Leukotrienes (LT's)
20 carbon fatty acid attached to membrane phospholipid molecules to produce PG's and LT's
Arachidonic Acid
Factors that cause growth by stimulaing cell division
Stress response and General Adaptation Syndrome are controlled by the
Nervous system and brain part involved in Fight or flight
hypothalmus and Sympathetic divsion of ANS
Reduction of blood flow to the kidneys promotes the release of
Renin causes the kidneys to retain Na+, which leads to
Water retention and elevated blood pressure, which helps presere body fluid volume in the case of severe bleeding
Hormones released by the Hypothalmis invloved in the resistance stage
Corticotropin releasing hormone (CRH), Growth hormone releasing hormone (GHRH), and Thyrotropin releasing hormone (TRH)
Stimulates the anterior pituitary to secrete ACTH which in turn stimulates the adrenal cortex to relase more cortisol
Corticotropin releasing hormone (CRH)
Stimulates gluconeogenesis by liver cells, breakdownof triglycerides into faty acids and catabolism of proteins into amino acids, also reduces inflamation
Causes anterior pituitary to secrete hGH
Stimulates the Anterior pituitary to secrete thyroid stimulating hormone
Thyrotropin releasing hormone (TRH)
