Male Reproductive System Flashcards

Study Notes

Male Reproductive System Terms

Corpus Spongiosum: A spongy tissue surrounding the urethra in the penis, preventing its collapse during erection.
Testis: Male reproductive organ that produces sperm and hormones, primarily testosterone.
Scrotum: A pouch of skin that contains the testes, regulating their temperature for optimal sperm production.
Cremaster Muscle: Muscle that elevates or lowers the testes in response to temperature changes for sperm production efficiency.
Inguinal Canal: A passage in the lower abdominal wall allowing structures to pass from the abdomen to the scrotum.
Epididymis: A coiled tube where sperm mature and are stored after being produced in the testes.
Ductus (vas) deferens: A muscular tube that transports sperm from the epididymis to the ejaculatory duct.
Efferent Ducts: Ducts that carry sperm from the rete testes to the epididymis, enabling maturation and storage.
Spermatic Cord: Bundle of structures, including the vas deferens, blood vessels, and nerves, connecting the testes to the abdominal cavity.
Ejaculatory Duct: Duct formed by the fusion of the vas deferens and seminal vesicle duct, leading to the urethra, allowing sperm and seminal fluid to enter.
Seminal Vesicles (glands): Glands that produce a fluid rich in sugar, providing energy for sperm and forming a major part of semen.
Prostate Gland: Gland that secretes a fluid that nourishes and transports sperm, also contributing to semen.
Prostate Urethra: Segment of the urethra that runs through the prostate gland.
Urethra: Tube that conducts urine from the bladder and sperm from the reproductive system to the outside of the body.
Membranous Urethra: Short segment of the urethra that passes through the pelvic floor muscles, connecting the prostate urethra to the penile urethra.
Penile or Spongy Urethra: The longest part of the urethra, located within the penis, allowing urine and semen to exit the body.
Corpus Cavernosum: Two columns of erectile tissue in the penis that fill with blood during erection, contributing to rigidity.
Glans Penis: The sensitive bulbous structure at the tip of the penis, covered by foreskin in uncircumcised males.
Prepuce or Foreskin: A fold of skin covering the glans penis, can be removed through circumcision.
Male Urinary Bladder: Contains urine, with muscle walls that contract to release urine through the urethra.
Bladder Rugae: Folds in the bladder lining that allow it to expand as it fills with urine.
