______ lie in between the tubules and secrete male sex hormones.

Interstitial cells

Indicate which of the following are true regarding the uterus.

It is a hollow muscular organ. It functions to harbor the developing embryo

Indicate which of the following statements are true about the ductus deferens

It is a muscular tube. It carries sperm from the epididymis to the ejaculatory duct.

Follicular phase

Maturation of ovarian follicles mediated by FSH

Epididymis

Promotes maturation of the sperm cells and stores sperm cells

Penis

Richly supplied with sensory nerve endings; conveys semen and urine outside of the body

Bulbo-urethral gland

Secretes a fluid that lubricates the end of the penis

Seminal vesicle

Secretes an alkaline fluid rich in fructose and prostaglandin that helps neutralize the acidic components of semen

Why is it important to maintain testes temperature at values lower than body temperature?

Sperm viability requires the lower temperature.

Ovulation

Surge in concentration of LH

The scrotum is lined by smooth muscles. Additionally the cremaster muscle is attached to the testes. Why are these muscles important?

They help regulate the testes temperature for optimal sperm production.

Indicate which of the following are the roles of the reproductive system.

corpus luteum

During ejaculation sperm are mixed with fluid from the seminal vesicles by contractions of the Blank______.

ejaculatory duct

Just outside the prostate, the ductus deferens unites with the duct of the seminal vesicle. The fusion of these two ducts forms the ____________ duct, which passes through the prostate and empties into the urethra.

ejaculatory duct

A tightly coiled tube on the outside of the testis that leads into the ductus deferens is the

epididymis

failure of the testes to descend

True or false: The testes develop within the scrotum before birth.

false because The testes actually develop in the body cavity and then migrate into the scrotum before birth.
