Document Summary
Male reproductive system i scrotum, testes & spermatic duct. Categorize reproductive structures as primary or secondary organs. Describe the layers and contents of the spermatic cord. Define the terms inguinal canal , deep inguinal ring and superficial inguinal ring . Primary sex organs gonads (testes: forms spermatozoa, secrete sex hormones (androgens, contained in scrotal sac, which can regulate temperature by pulling up the sac. Secondary sex organs: transmission of sperm, ducts epididymis, vas deferens, ejaculatory duct, urethra, accessory glands seminal vesicles, prostate gland & bulbourethral gland, copulatory organ penis. Sac-like, supports and protects the testes and regulates their position. Maintain testes at 3 c below body temperature. Coverings are continuous with the fascia of the spermatic cord & abdominal wall: superficial fascia/connective tissue of the scrotum contains the dartos muscle (contracts skin when the scrotum is elevated) The spermatic cord connects to the testis and can be pulled out in a cadaver. Development of testes begins near/higher than the kidneys.
