Kinesiology 3222A/B Lecture Notes - Lecture 22: Spermatic Cord, Defecation, Ischiocavernosus Muscle
Document Summary
Learning outcomes: describe the anatomy of each component of the external genitalia, describe spermatogenesis and identify the important stages of sperm development, examine the role of accessory organs in the production of semen. System of ducts: transport sperm: epididymis, comma shaped, leads in vas deferens (ductus deferens, ductus deferens, ejaculatory ducts, urethra, accessory sex glands: produce semen. Seminal vesicles (2: superior to prostate, prostate, bulbourethral glands (2, male gonads: produce sperm and hormones (testosterone, testes, external genitalia, penis. From anus to end of penis: changes name depending on location to become scrotal and penile raphe. Femoral artery: external pudental artery, anterior scrotal artery. Spermatogenesis: creation of sperm, hormone secretion, anterior pituitary stimulates lh, lh stimulates testosterone, blood supply: testicular artery/vein. Coverings of the testes: 2 tunic layers surround testes, tunica vaginalis, double layered with a parietal and visceral layer, protects and allows movement due to serous fluid bw layers, accumulation of fluid is hydrocele, tunica albuginea.
