Study Notes
Overview
- The male reproductive system is responsible for producing, storing, and transporting sperm cells for fertilization.
- The system consists of the testes, epididymis, vas deferens, seminal vesicles, prostate gland, urethra, and penis.
Testes
- Produce sperm cells through a process called spermatogenesis.
- Located outside the abdominal cavity in the scrotum, a sac of skin and muscle.
- Regulated by the hypothalamic-pituitary-testicular axis.
Epididymis
- A tube-like structure that stores and transports sperm cells from the testes.
- Divided into three regions: head, body, and tail.
- Sperm cells mature and become motile during their passage through the epididymis.
Vas Deferens
- A muscular tube that transports sperm cells from the epididymis to the urethra.
- Also known as the ductus deferens.
- Has a thick muscle layer that contracts to propel sperm cells during ejaculation.
Seminal Vesicles
- Glandular structures that produce seminal fluid, which nourishes and transports sperm cells.
- Located behind the bladder and urethra.
- Contribute to the formation of semen.
Prostate Gland
- A gland that produces a protein-rich fluid that makes up part of semen.
- Located beneath the bladder and surrounds the urethra.
- Plays a role in regulating the flow of urine.
Urethra
- A tube that carries semen and urine out of the body.
- Passes through the prostate gland and penis.
- Has a sphincter muscle that controls the flow of urine and semen.
Penis
- The external male genital organ.
- Composed of three parts: root, shaft, and glans.
- The glans is covered by a fold of skin called the foreskin.
Ejaculation
- The process by which sperm cells are propelled out of the penis during sexual arousal.
- Involves the contraction of muscles in the vas deferens, seminal vesicles, and prostate gland.
- Results in the release of semen, which contains sperm cells, seminal fluid, and prostate fluid.
