MICROANATOMY

Detailed explanation-1: -Here, the vas deferens joins with the seminal vesicle to form the ejaculatory duct, which passes through the prostate and empties into the urethra. When ejaculation occurs, rhythmic muscle movements propel the sperm forward.

Detailed explanation-2: -The vas deferens (singular) is also called a ductus deferens or a sperm duct. This long muscular tube runs from the epididymis into the pelvic cavity behind your bladder and connects to your urethra through a structure called the ejaculatory duct.

Detailed explanation-3: -The principal function of the vas deferens is to transport sperm from the testes and out of the body during ejaculation. Here’s how it works: During arousal, muscle contractions help move the sperm from the epididymis through the vas deferens.

Detailed explanation-4: -Etymology. Vas deferens is Latin, meaning “carrying-away vessel"; the plural version is vasa deferentia. Ductus deferens is also Latin, meaning “carrying-away duct"; the plural version is ducti deferentes.
