Transcript

  • 1.  Adrenal Glands Ovaries (Women Only) Pancreas (islets of langerhans) Parathyroid glands Pineal Glands Pituitary Glands Testes (Men Only) Thymus Gland Thyroid Gland
  • 2.  Located above each of the kidneys. 2 sections: adrenal cortex & adrenal medulla Outer- manufactors several different families of hormones. The hormones regulate secondary sexual characteristics. All hormones secreted by the adrenal cortex are steroid hormones.Adrenal Glands
  • 3. Ovaries (Women Only) Females gonads located in the lower abdomen pelvic cavity of the female. This is a part of the reproductive system as well. The ovaries is where an unborn fetus lives for a gestational period of forty weeks until birth.
  • 4. Pancreas Located along the lower curvature of the stomach. The only organ in the body that has both endocrine and exocrine functions. The exocrine portion releases digestive enzymes through a duct into the duodenum of the small intestines.
  • 5.  Four tiny parathyroid glands are located on the dorsal surface of the thyroid gland. Parathyroid hormone secreted by these glands regulates the amount of calcium in the blood. If the blood calcium levels fall too low, parathyroid hormone levels in the blood are increased and will stimulate bone breakdown to release more calcium into the blood.
  • 6. Pineal Gland Small pine cone shaped gland that is part of the thalamus region of the brain. Glands secrete melatonin, a hormone now well understood, but that plays a role in regulating the body’s circadian rhythm.
  • 7. Pituitary Gland located underneath the brain Small marble shaped gland that is divided into an anterior lobe and a posterior lobe. Both lobes are controlled by the hypothalamus(a region of the brain active in regulating automatic body responses. Anterior lobe secretes several different hormones.(growth, thyroid stimulating, adrencorticotrophin, prolactin, follic le-stimulating and luteinizing hormones, melanocyte-stimulating & antidiuretic and oxytocin hormones)
  • 8.  Two oval glands located in the scrotal sac of the male. The male gonads Produce gametes, sperm and the male sex hormone, testosterone. Testosterone produces the secondary sexual characteristics and regulates sperm production
  • 9.  A part of the immune system as well. Is also one of the endocrine glands because it secretes the hormone thymosin (it is important for the proper development of the immune system. It is present at birth and grows to its largest at puberty. At puberty is shrinks and is connected with other tissues.Thymus Gland
  • 10. Thyroid Gland Is the shape of a butterfly and it has a right and left lobe. Located on either side of the trachea and larnyx The thryoid cartilage, or Adams apple is located just above the thyroid gland. Produce the hormones thyroxine and triiodothyronine. These hormones regulate the production of energy and heat in the body to adjust the body’s metabolic rate.
