Presentation Transcript

  1. Endocrine Systematics Barrett Peters Biomedical Research

  2. Function and Format • Made up of all glands and hormones of the body • Stimulated by nervous system, chemical receptors, and other hormones. • Glands secrete hormones • Regulates homeostasis

  3. Organs/Peripherals • Adrenal gland • Hypothalamus • Pancreas • Ovaries (f)/Testicles (m) • Parathyroid gland • Pineal gland • Pituitary gland • Thymus gland • Thyroid gland

  4. Adrenal Gland • Adrenal Cortex creates hormones to: -break down proteins -reduce inflammation -regulate mineral ions -regulate growth • Adrenal Medulla creates hormones to increase blood flow to brain and muscles during a “fight or flight” response

  5. Hypothalamus • Part of the nervous system • Specialized neurons influence hormone production • Controls other hormone producing organs/glands by releasing stimulating hormones

  6. Pancreas • Serves functions as endocrine organ and exocrine organ • Produces the hormone insulin to regulate blood sugar levels.

  7. Ovaries/ Testicles • Ovaries create the female sex hormones • Estrogen develops female secondary sex characteristics and basic growth. • Progesterone maintains a suitable environment for an egg during ovulation. • Testicles produce male sex hormones. • Testosterone induces growth and development of male muscles, bones, and sex organs.

  8. Parathyroid Gland • Located on the posterior side of the thyroid gland • Produces the hormone parathyroid hormone • Regulates calcium levels in blood, bones, and kidneys

  9. Pineal Gland • Located near the thalamus in the brain. • Produces melatonin to regulates human circadian rhythm (sleep-wake cycle) • Triggered by photoreceptors to only produce Melatonin in low light conditions.

  10. Pituitary Gland • Made up of 2 parts: -anterior -posterior • Posterior section is part of Hypothalamus that regulates water levels in the body and aspects of pregnancy. • Anterior region produces growth hormones and hormone stimulating hormones.

  11. Thymus Gland • Prepares the body for growth during fetal development. • Helps defend the body from pathogens. • Stops being active during puberty and eventually gets replaced by adipose tissue.

  12. Thyroid Gland • Located at base of neck around trachea. • Produces three different hormones: Calcitonin, T3, and T4 • Regulates calcium levels if they get too high and metabolic activities.

  13. Relation to other systems • During a fight-or-flight response, blood flow from the cardiovascular system is increased to the muscular and nervous system. • Digestion and blood sugar levels are regulated by hormones produce by the endocrine system. • Calcium levels in bones and steady growth produced by the skeletal system are also regulated by hormone releasing gland.

  14. Relation (cont.) • Reproductive organs and pregnancy are affected by glands in the endocrine system. • Aiding the immune and lymphatic systems that are fighting disease, the endocrine system reduces inflammation in parts of the body.

  15. Diabetes • Diabetes is a disease related to the lack of production of insulin. • Without insulin, the body has no way to monitor and regulate blood sugar levels. • If not monitored, this disease could possibly be fatal by either having too high or too low blood sugar.

  16. Fun Facts • The Hypothalamus is what makes you hungry and/or thirsty. • The endocrine system can directly affect human behavior. • There are a total of 30 different hormones in the human body.

  17. GAMETIME!!! • Pick a partner • One of you will be allowed to pick up functions, the other will pick up organ names. • Coordinate with your partner to bring me the correct pairs first. • If you get one wrong you start all over.
