A&P II The Male reproductive system lecture (Part 2) Flashcards

The process of sperm production is known as what?

Spermatogenesis begins at the outermost layer in the ????? tubules and proceeds toward the ????.

These stem cells divide by mitosis to produce two daughter cells.

When spermatogonia divide to produce two daughter cells, what do the two daughter cells do?

A primary spermatocyte begins meiosis and forms a what?

Secondary spermatocytes differentiate into what?

Spermatids differentiate into what?

Spermatozoa lose contact with the wall of the ???? and enter fluid in the ????.

The contents of the seminiferous tubules include what?

Spermatogenesis involves three integrated processes. List them.

At spermiation, a spermatozoon loses attachments to ???? and enters the ?????? of the seminiferous tubules

Nurse cells, or sertoli cells, affect what?

Nurse cells have 6 major functions. what are the?

The anatomy of a spermatozoon is fairly simple. give the 4 parts.

A mature spermatozoon lacks many organelles such as?

The loss of organelles in a mature spermatozoon results in what?

Where do mature spermatozoon get their nutrients from?

The testes produce physically mature spermatozoa. Are these cells able to fertilize an oocyte?

Other parts besides the testes play a role in sperm maturation. What kind of tasks do they preform?

As sperm mature in the testes they detach from the ????? and become free in the lumen of the ??????.

While the sperm is in the lumen of the seminiferous tubules, they are incapable of locomotion. How are the then moved to the next location?

This is the first organ after the testes that is the start of the male reproductive tract.

What are the three parts of the Epididymis?

What is the function of the epididymis?

Identify A

Identify B

Identify C

Even though the spermatozoa that leave the epididymis are mature, they remain ?????.

To become motile, spermatozoa undergo what?

What are the two steps in capacitation?

What is another name for the Vas Deferens?

The Vas deferens begins at the tail of the ???? and as a part of the spermatic cord, ascends through the ?????.

The vas deferens passes along what two glands that add to the sperm?

The lumen of the vas deferens larges into a what?

The wall of ampulla of the vas deferens contains a thick layer of what?

The ductus deferens is lined by what?

Spermatozoa and other fluids are propelled through the ductus deferens by what?

The ductus deferens can store spermatozoa for several months in a state of what?

This is a short passageway at the junction of ampulla and the seminal gland duct.

The ejaculatory duct penetrates the wall of what gland?

The urethra is used by what two systems?

The urethra is divided into what three regions?

List the three accessory gland to the male reproductive system.

The male reproductive accessory glands have 4 main functions. what are they?

The seminal glands produce what kind of secretions?

The secretion produce by the seminal gland has 4 defining characteristics. what are they?

Why is the fructose produce by the seminal gland important?

Why is the prostaglandin that is produced by the seminal gland important?

Why is the fibrinogen produced the seminal gland important?

Why is the alkaline produced by the seminal gland important?

The first step in capacitation is initiated by what?

This gland is a small, muscular organ that encircles the proximal portion of the urethra found below the urinary bladder.

Prostatic fluid, in terms of pH, is very what?

Prostatic fluid has what effect on sperm?

Prostatic fluid contains an antibiotic known as what?

What is another name for the Bulbo-urethral gland?

The bulbo-urethral gland secretes what?

What is the function of the secretions of the bulbo-urethral gland?

The typical amount of semen ejaculated is what?

What is the normal range of spermatozoa that is ejaculated

This is the volume of fluid produced by ejaculation

The ejaculate contains what three things?

What is the main external male genitalia and what is its function?

These hormones that are released by the anterior lobe of the pituitary gland play a part in male reproduction.

FSH and LH are released in response to what other hormone?

GnRH (gonadotropin-releasing hormone) is synthesized where?

GnRH (gonadotropin-releasing hormone) is carried to the pituitary by what?

GnRH (gonadotropin-releasing hormone) is secreted in pulses at ????? minute intervals.

GnRH (gonadotropin-releasing hormone) controls the rate of secretion of what two hormones?

LH stimulates the release of what hormone?

FSH and testosterone target what cells of the seminiferous tubules?

Nurse cells promote what two things?

Nurse cells secrete what?

Spermatogenesis is regulated by what three things?

As spermatogenesis accelerates, inhibin secretion does what?

Inhibin does what two things?

When FSH levels goes up, what happens to inhibin production?

If FSH levels decline, what happens to inhibin production?

LH targets what cells of what organs?

LH induces the secretion of what hormone?

What is the most important androgen hormone?

This testosterone stimulates what?

What affect does testosterone on CNS functions?

What effect does testosterone have on the metabolism?

What kind of secondary sex characteristics are started by testosterone?

Around what week of fetal development does the production of testosterone develop and when does it reach prenatal peak?

The secretion of this factor by nurse cells leads to regression of what ducts?

An early surge in testosterone levels stimulates differentiation of ??????? system and ????? and affects ????? development.

Testosterone programs hypothalamic centers that control what three things?

This hormone is produced in relatively small amounts, 70% is converted from circulating testosterone and the other 30% is secreted by interstitial nurse cells.
