  1. TOPIC: Regulation Aim: Explain the function the different endocrine glands. Do Now: Ditto – Human Nervous System Mapping Review HW: Ditto – Did you Know?

  2. X A B

  3. X A C B • Which cells are target cells for hormone A? Explain why. • Which cells are target cells for hormone B? Explain why.

  4. Endocrine Glands

  5. Hypothalamus

  6. Part of the brain • Produces hormones that control pituitary gland

  7. Pituitary Gland

  8. Controls activities of other glands (formerly known as the MASTER GLAND)

  9. Hormones: • Thyroid stimulating hormone (TSH): stimulates thyroid

  10. Growth Hormone (GH): regulates growth (bones, muscles, tissues)

  11. 14-year old Khagendra Thapa Magar shown in the picture with another boy is only 50 centimetres (20 inches) tall and has been submitted to the Guinness world record as the world's smallest person. The previous world record holder was a Jordanian boy at 25.5 inches tall. Weighing only 4.5 kilograms, he is shown in exhibitions to collect fund for his education.

  12. Follicle stimulating hormone (FSH) and leutinizing hormone(LH): stimulate testes and ovaries

  13. Thyroid

  14. Releases THYROXINE • Regulates rate of metabolism

  15. This X-ray shows how an enlarged right lobe of the thyroid has moved the trachea to the patient's left. The trachea (outlined in light yellow) should be straight from the mouth down to the lungs, but in this patient it is compressed and displaced far to the left.

  16. Parathyroid glands

  17. Release PARATHORMONE • Controls level of calcium in blood

  18. Adrenal Glands

  19. Release adrenaline in times of stress, emergency

  20. Increases heart rate, blood pressure, breathing rate, sweating

  21. Islets of Langerhans

  22. Cells on the PANCREAS • Release:

  23. 1.Insulin: lowers blood glucose level 2.Glucagon: increases blood glucose level

  24. Gonads

  25. a. Ovaries

  26. Release: • Estrogen = development of secondary sex characteristics

  27. Progesterone = prepares uterus for fertilization

  28. b. Testes

  29. Release testosterone • sperm production • development of male secondary sex characteristics

  30. Let’s summarize… • Explain how the pituitary gland is controlled. • Describe where the pituitary gland is located. • Describe some of the hormones secreted by the pituitary gland. • Describe the function of the thyroid gland. • Identify the two hormones secreted by the pancreas? Explain the function of these two hormones. • Where are the adrenal glands located? • Explain he function of the hormone released by the adrenal glands. • Explain the differences between the male and female gonads.

  31. Identify the gland being described. • Produces thyroxine • Regulates calcium levels in the blood • Is called the master gland. • Controls the pituitary gland • Secretes GH, TSH, LH, and FSH
