WGU C107 Module 42 The Male Reproductive System correctly answered 2023Which of the following is NOT a structure associated with the testes? Ampulla - The ampulla is the widening of the distal end of the vas deferens. - The lobules are wedge-shaped divisions of the testes formed by the septa. Which of the following structures is NOT correctly matched with its description? Lobules - Circular shaped divisions of the testes. Which of the following structures of the testes is NOT correctly matched with its function? Type A spermatagonia - Undergo meiosis to form spermatid. - Type B spermatagonia mature to become primary spermatocytes which undergo meiosis to become spermatids. Type A cells remain in the seminferous tubules and maintain the stem cell populations. Which of the following is located solely within the scrotum? Epidydimus - The epidydimus coils around the superior edge of the testes and is located solely in the scrotum. Which of the following composes part of the spermatic cord? Vas deferens - The vas deferens originate in the scrotum but enter the abdominal cavity through the spermatic cord. Which of the following sections of the urethra is NOT properly matched with its description? Spongy urethra - Receives semen from the ejaculatory duct. - The spongy urethra also known as the penile urethra runs the length of the penis. The prostatic urethra receives semen from the ejaculatory duct. What type of contractions do the ductus deferens use to move or transport the sperm to the ejaculatory duct? Peristaltic contractions - These type of contractions occur in smooth muscle and act to propel substances in a single direction. Which structure is under involuntary control and prevents urine from exiting the bladder during ejaculation? Internal urethral sphincter - The internal urethral sphincter closes during ejaculation to prevent urine from entering the urethra and sperm from entering the bladder. Which following are functions of the epididymis? All of these are functions of the epididymis. - All of the listed functions occur in the epididymis. Which glands are located at the base of the penis? Bulbourethral glands - These pea sized glands are located near the base of the penis. Which of the following does NOT accurately describe the prostate gland? It is about the size of a pea. - The prostate gland is normally close to the size of a walnut. Which gland is NOT properly matched with where its ducts empty? Seminal vesicles - Ampulla of the ejaculatory duct - The seminal vesicles empty into the ampulla of the vas deferns and help to form the ejaculatory duct. Which structure contributes the least amount of fluid to the semen? Bulbourethral gland - The bulbourethral glands also known as Cowper's glands provide 1% or less of the volume to the semen. Which of the following is NOT correct about semen? It provides fats to nourish the sperm. - The semen provides sugars such as fructose for quick energy for the sperm. Which of the following is NOT one of the primary functions of the secretions from the seminal vesicles? It provides lubrication for intercourse. - The Bulbourethral glands, not the seminal vesicles, specifically provide lubrication for intercourse. Which of the following is NOT part of the structure of the penis? Spermatic cord - The spermatic cord connects the structures in the scrotum with the abdominal cavity. Which of the following correctly describes the scrotum? Is moved up and down by the cremaster muscle. - The cremaster muscle moves the scrotum closer to the body or further away regulating its temperature. What is the primary reproductive function of the penis? Transport semen outside of the body. Which of the following occurs during spermiogenesis? Sertoli cells remove excess cytoplasm. - Sertoli cells remove this excess cytoplasm to allow for efficient movement of the spermatid. Which of the following is an INCORRECT statement about the process of sperm production? Secondary spermatocytes are diploid cells that produce spermatids. - Secondary spermatocytes are produced after primary spermatocytes undergo meiosis I which results in two haploid cells. Which population of cells is located at the periphery of the seminiferous tubule? Type A spermatogonia - Type A spermatogonia stay at the periphery of the seminiferous tubules to maintain the stem cell population. Which portion of the sperm contains enzymes that help to penetrate the egg? The acrosome - The acrosome is part of the head of the sperm and contains enzymes that help penetrate the egg. Which of the following hormones is not correctly matched with its function? Testosterone - Preventing fetal development of female structures. - Testosterone promotes the development of male reproductive organs and male secondary sex characteristics
