Reproductive System

The primary sex organs, or gonads, are the organs responsible for gamete production. In males, the testes are the gamete-producing organs; in females, the ovaries accomplish this important function. The remaining structures of the reproductive system are called accessory reproductive organs.

Which of the following is considered a primary sex organ in males?

Male Reproductive structures

The pampiniform plexus absorbs heat from the testicular arteries, cooling the arterial blood before it enters the testes.

Which of the following structures help(s) to keep the testes at a cool temperature?

They are a highly effective method of birth control.

The part of the ductus deferens that lies in the scrotum is cut.

Which statement about vasectomies is FALSE?

place sperm storage sites nearer to the penis

Spermatogenesis requires a cooler temperature than the core body temperature.

to reduce the chance of infection from the enteric bacteria

The reason that the testes are suspended in the scrotum is to __________.

The spongy urethra makes up 75% of the male urethra.

Which of the following structures makes up most of the male urethral length?

The ejaculatory duct does not pass through the inguinal canal.

The prostatic urethra does not pass through the inguinal canal.

The epididymis does not pass through the inguinal canal.

Which of the following structures passes through the inguinal canal?

What is Semen made of? Sperm or Semen

Microscopic appearance of testes

Functional Anatomy of the Male Reproductive System

When they contract, they cause wrinkling of the scrotal skin.

This is the function of the dartos muscle.

They surround the seminiferous tubules and contract rhythmically to squeeze sperm and testicular fluid through the tubules out of the testes.

They form a duct that conveys sperm from the epididymis to the prostate gland.

This is the function of the vas deferens.

The cremaster muscles elevate the testes.

Which of the following statements about myoid cells is true?

Testis and Epididymis 

epididymis, seminiferous tubules, ampulla, vas deferens, prostatic urethra, ejaculatory duct, spongy urethra

The following list represents the correct order of structures through which sperm will pass: seminiferous tubules, epididymis, vas deferens, ampulla, ejaculatory duct, prostatic urethra, spongy urethra.

epididymis, ampulla, seminiferous tubules, vas deferens, spongy urethra, prostatic urethra, ejaculatory duct

ejaculatory duct, epididymis, seminiferous tubules, vas deferens, spongy urethra, prostatic urethra, ampulla

In order, list the structures sperm will pass through from the testes to the external urethral orifice.

Sperm is actually a minor component of semen. Most (about 70%) of semen fluid volume is attributed to secretions of the seminal glands (vesicles).

Male Reproductive Anatomy, Ejaculatory Pathway & Semenoegnic Glands

Viable sperm cannot be produced in abundance at core body temperature (37&deg;C). The superficial location of the scrotum, which holds the testes, provides a temperature about 3&deg;C lower than core temperature, allowing viable sperm to be produced.<br><br>The scrotum is affected by temperature changes. When it is cold, the scrotum reduces its surface area by becoming heavily wrinkled; it also shortens to pull the testes closer to the body wall. In warm temperatures, the scrotum becomes flaccid and loose to increase its surface area, and hangs lower to keep the testes away from the warmer body trunk.

In response to warmth, the scrotum __________.
