To do this, the left and . D. passes through the inguinal canal and enters the pelvic cavity. Sperm then travels through . 3. Contractions of the _____ muscles result in ejaculation. The structures of the male reproductive system include the testes, the epididymides, the penis, and the ducts and glands that produce and carry semen. The epididymis is a long coiled structure topping the testis, and it receives immature sperm from the testis and stores them as they mature. It is the vas deferens which are ligated (severed or cut) during a vasectomy, a procedure for male surgical sterilization. The head of the epididymis is located on superior pole of testis. B) estrogen is secreted by the developing follicle in the follicular phase of the cycle. Ductus Deferens The ductus deferens, also known as the vas deferens, is a tiny muscular tube in the male reproductive system that carries sperm from the epididymis to the ejaculatory duct. The vas deferens is a muscular tube adjacent to the pros- tate that extends from the epididymis, passing through the inguinal canal into the peritoneal cavity and opening into The ductus deferens, or the vas deferens, is a male anatomical part; there are two of these ducts and their purpose is to carry ejaculatory sperm out of the epididymis. c. They are responsible for penile erection. FALSE 4) When a couple is having difficulty conceiving a child, it is necessary to investigate the sperm 2. sperm are moved from the ductus deferens to the ampulla and urethra. B. efferent ductules. Semen is expelled from the urethra. A) gravity

.

C 14. Page Ref: 1026. The epididymis is an essential component of the male reproductive tract. When ejaculation occurs, sperm are forcefully expelled from the tail of the epididymis into the vas deferens. The vas deferens contains a structure called the ampulla, which is enlarged and acts as a reservoir for sperm before sexual arousal. During ejaculation, sperm exit the tail of the epididymis and are pushed by smooth muscle contraction to the ductus deferens (also called the vas deferens). It can take about 45 minutes to 12 hours for a sperm to reach the Fallopian tubes and meet the egg. Sperm leave the testes through a series of efferent ducts that enter the epididymis. During ejaculation, sperm exit the tail of the epididymis and are pushed by smooth muscle contraction to the ductus deferens (also called the vas deferens).

D. interstitial cells. Definition. The process of sperm maturation in the epididymis can take . C) peristaltic contractions. Sperm move the the Vas Deferens to begin traveling through the male body ("The Sperm Highway").

It is a site of sperm storage and maturation until the time of their discharge to the ductus deferens or vas deferens . Sperm are produced in the 5. Peristaltic contractions: Term. The ampulla of the ductus deferens merges with the duct of the seminal vesicle to form the ejaculatory duct. The spermatic cord is an enclosed sheath which includes the vas deferens, , and . 5. E. produce seminal fluid. Vasectomy: C) the corpus luteum is formed from the ruptured follicle after ovulation. At the end we will conclude with clinical points . The ductus deferens joins with the duct of the seminal gland to form . Structure. A vasectomy is a form of birth control for men that is performed by surgically cutting or blocking the vas deferens so that sperm cannot be ejaculated out of the body. Prostate Gland contributes more fluid to the semen. This is a gland that produces fluid that is a major component of semen. The vas deferens, also called ductus deferens, are long muscular tubes that transport sperm from the the epididymis to the urethra. Sperm are moved along the ductus deferens (vas deferens) by - ciliary action - peristaltic contractions - hydraulic action - suction - hydrostatic force peristaltic contractions The organ that carries sperm from the epididymis to the urethra is the - ductus deferens (vas deferens) - ejaculatory duct - seminal gland (seminal vesicle) The epididymis sits directly on top of each testis. Sperm are produced in the testicles and develop to maturity while traveling from the seminiferous tubules through the epididymis into the vas deferens. One may also ask, where in the ducts is the sperm maturation completed? The sperm ducts (or ductus deferens) are a complex set of structures of various kinds whose main functions are two fold: to allow the transit of sperm from the testicles to the outside of the body and allow the maturation of the sperm cells themselves. FALSE 3) The hormone oxytocin combines with enzymes in semen to enhance sperm motility. Vas deferens - the duct that transports sperm from the epididymis to the ampulla (a dilated terminal part of the duct), ready for ejaculation. C) They are responsible for penile erection. 3. Which cell types is formed at the end of the first meiotic division 4. When a couple is having difficulty conceiving a child, it is necessary to investigate the sperm of the male. In this article we aim to cover the embryology, anatomy, histology and functions of the epididymis. The seminal vesicles and prostate gland add fluids to the sperm to create semen.

The ductus deferens is located along the anterior and superior sides of the bladder as a result of the testes descending into the scrotum from the abdominal cavity during fetal development. The ductus deferens enters the abdominopelvic cavity through the inguinal canal and . 3) Sperm are moved along the ductus deferens (vas deferens) by A) hydrostatic force. D) moves sperm through the ductus deferens. A) They are responsible for penile erection. Bulbo-urethral gland: . It stores sperm for maturation. A man's sperm, which is carried in semen that's made by glands such as the prostate, is kept in a duct called the vas deferens. C) peristaltic contractions. The release process starts when the penis fills with blood and becomes erect. In a _____, each ductus deferens is cut and either a segment removed and the ends ties ( or cauterized ) or silicone plugs are inserted: Definition. When ejaculation occurs, sperm is forcefully expelled from the tail of the epididymis into the deferent duct. C) peristaltic contractions. 2.

B) a narrow opening that links the scrotal chamber with the peritoneal cavity. Ejaculatory ducts: These ducts are formed by the fusion of the vas deferens and the seminal vesicles. The ampulla of the ductus deferens merges with the duct of the seminal vesicle to form the ejaculatory duct. D. cover and protect most of the testes.

Both tetrads and crossovers are seen during meiosis. True. The epididymis consists of three parts, the caput (head), corpus (body), and cauda (tail.) If sperm aren't ejaculated, they're eventually reabsorbed by the epididymis. In a _____, each ductus deferens is cut and either a segment removed and the ends ties ( or cauterized ) or silicone plugs are inserted: Definition.
