Matching: Structure and Function of the Male Reproductive System Testes A. Subcutaneous smooth muscle of the scrotum. Scrotum B. The formation of sperm in the seminiferous tubules of the testes. Dartos muscle C. Series of small bands of skeletal muscle that descend as an extension of the internal oblique muscle through the spermatic cord to surround the testes. Cremaster muscle D. A type of cell that secretes testosterone: located between seminiferous tubules. Also known as a Leydig cell. Seminiferous tubules E. Spermatogenic cells formed after meiosis I that enter meiosis II. Spermatogenesis F. Male gonads. Spermiogenesis G. The process of maturation of spermatids into sperm. Sustentacular cells H. Supporting structure for the testes, consists of loose skin and underlying subcutaneous layer. Spermatogonia I. Site of sperm maturation - the process by which sperm acquire motility and the ability to fertilize. Secondary spermatocyte J. A tightly coiled duct, located in the testis, where sperm are produced (site of spermatogenesis). Spermatids K. A supporting cell in the seminiferous tubules that nourishes, supports, prepares, releases sperm, and forms the blood-testis barrier. Also called a Sertoli cell. Interstitial cells L. The four haploid cells resulting from meiosis II but prior to spermiogenesis. Epididymis M. The duct that carries sperm from the epididymis to the ejaculatory duct. Vas deferens N. Stem cells in the seminiferous tubules that undergo mitosis or differentiate and become primary spermatocytes that enter meiosis. Inguinal canal O. A passageway in the anterior abdominal wall between the abdominopelvic cavity and scrotum.

These are structures where sperm cells pass through from the testes down to the exterior. Arrange them in the correct order: Urethra, seminiferous tubules, Vas Deferens, Epididymis, Rete Testes, Ejaculatory duct, Urethral orifice Discuss the function of the following: Prostate Gland Seminal vesicle Cowper's gland
