Reproduction and Development Review: 1. What is the function of: Seminiferous tubules- The seminiferous tubules are the site of the germination, maturation, and transportation of the sperm cells within the male testes Intestinal cells- Produce testosterone (primary male sex hormone) Nurse cells- Support and surround developing sperm. Produce androgen binding protein. Epididymis- [sperm storage]- after the seminiferous tubules. Mature here. Vas deferens- After epididymis, thru vas deferends during ejaculation Seminal glands (seminal vesicles)- produce semen. Rich in fructose, alkaline, Prostate gland- Main function to secrete prostate fluid, one of the components of semen. The muscles of the prostate gland also help propel this seminal fluid into the urethra during ejaculation. Also produces semen -20% Bulbourethral glands (Cowper’s glands)- Adds fluid to the semen. [Makes remaining semen.] Ovaries- egg maturation, produce estrogen and progesterone. Ovarian follicle- Fluid-filled sac that contains an immature egg, or oocyte. These follicles are found in the ovaries. During ovulation, a mature egg is released from a follicle. [Where the estrogen and pro. Is made.] Corpus luteum - remaining follicle after egg is ovulated. Secretes progesterone; responsible for decidualization of endometrium [and some estrogen.] Preovulatory - Occurring or existing in or typical of the period immediately. [Estrogen] Postovulatory - Occurring, being, or used in the period following postovulatory [progesterone] Corpus albicans - Develops from the ovulated follicle by proliferation of granulosa and the theca internal cells. Progesterone stimulates thickening of endometrium by secretion. Begins to involute by day 22 in the absence of pregnancy. Involution complete by day 26. [degenerated corpus leuteum ]
