Endocrine System 3

Endocrine System III: In this lecture, Professor Diamond finishes her discussion of the endocrine system. She begins with the adenohypophysis in the pituitary gland, and describes how the production of growth hormone promotes uptake of protein. She also introduces the adrenocorticotrophic hormone (ACTH), which acts on the adrenal cortex, and follicle stimulating hormone (FSH), which acts on the ovaries in females and on the seminiferous tubules in males. She further describes luteinizing hormone (LH), which affects ovulation in females and testosterone production in males. She reviews an earlier discussion of thyroid stimulating hormone and then mentions prolactin, which promotes milk production in the mammary gland. Afterwards, Professor Diamond moves on to the next topic , the female reproductive system. She diagrams the female reproductive system, including the uterus, fallopian tubes, and ovaries. Professor Diamond then begins walking through each individual component of the female reproductive system, beginning with the ovaries. She discusses the process of ovulation and how follicles develop into eggs in the ovary. She follows the pathway of an egg through the fallopian tubes, and discusses normal and unusual occurrences during pregnancy.
