The testes contain seminiferous tubules, composed of several hundred tightly coiled tubules lined with germs cells. These tubules serve as the site of sperm production. Inside of these tubules spermatogonia progress to spermatocytes, then spermatids, and finally sperm. Also inside, sustentacular cells serve as a means of support. These cells control the environment by removing wastes, providing nutrients, and providing antibody protection as well as regulating sperm production. Interstitial cells outside of the tubules secrete testosterone and stimulates spermatogenesis.
Describe the structure and function of the epididymis, ductus (vas) deferens, ejaculatory duct and urethra. Relate the location and storage of sperm to a vasectomy. …show more content…
Describe how the testes “relocate” during development, including the role of the inguinal canal and the resulting structure and function of the spermatic cord. Describe a common medical problem associated with the inguinal canal. Describe the structure and function of the scrotum, and state the advantages of having the testes descend out of the body cavity. The testes initially develop in the abdominal cavity while contained in the embryo. They then descend through the inguinal canal into the scrotum. This forms the spermatic cord between the testes and abdominal wall. This cord contains the testicular artery, vein, lymphatic vessel, nerve, and the ductus deferens and is composed of smooth muscle. An inguinal hernia occurs when the intestine protrude through the inguinal canal. The scrotum is a pouch outside of the body, holding the testes. This provides an environment that is a few degrees cooler than the body to aid sperm production.
There are 3 accessory glands that contribute to the formation of semen. Discuss each gland including A) name and location, B) contents and role of the fluid produced by each gland, and C) percentage of semen volume contributed by each. Explain how and why the prostate gland causes problems for aging
