5 Questions
What are the general functions of the reproductive system?
The general functions of the reproductive system include producing gametes (sperm and egg cells), providing a system for fertilization, and supporting the development and nourishment of the embryo and fetus.
What are the internal reproductive organs of the male reproductive system?
The internal reproductive organs of the male reproductive system include the testes, ducts, and accessory glands.
What is the function of the epididymis in the male reproductive system?
The epididymis is responsible for carrying the sperm produced in the testes to the point of ejaculation from the penis.
What are the components of the ductus deferens/ejaculatory duct?
The ductus deferens is the dilated continuation of the epididymis and joins to the duct of the seminal vesicle at the ejaculatory duct. It is about 2 cm long.
How many seminiferous tubules are present in the testes?
There are approximately 800 seminiferous tubules present in the testes, where sperm production takes place.
Study Notes
Male Reproductive System
- The general function of the reproductive system is to produce sex cells and support the union of sex cells to produce a new individual.
Male Internal Reproductive Organs
- The testes are paired organs, 4.5 cm long and 2.5 cm wide, responsible for sperm production.
- Each testis contains 800 seminiferous tubules, where sperm production occurs.
- The seminiferous tubules are lined with germinal tissue, containing spermatogenic cells and sustentacular cells.
- The tunica albuginea is a layer of connective tissue surrounding the testes.
Accessory Ducts
- The epididymis is a system of ducts that carries sperm from the testes to the point of ejaculation.
- The epididymis is divided into several parts: seminefrous duct, tubule recti, rete testes, and efferent duct.
- The ductus deferens, also known as the vas deferens, is a continuation of the epididymis and is located over the spermatic cord.
- The ductus deferens joins the duct of the seminal vesicle at the ejaculatory duct, which is approximately 2 cm long.
- The urethra is the final duct that carries sperm out of the body during ejaculation.
