1.
Undescended testicles
Correct Answer
D. Cryptorchism
Explanation
Cryptorchism is the correct answer because it refers to a condition in which one or both testicles fail to descend into the scrotum. This condition is commonly seen in newborn boys and may resolve on its own within the first year of life. If the testicles do not descend spontaneously, surgical intervention may be required to prevent complications such as infertility or an increased risk of testicular cancer. Anorchism refers to the absence of testicles, phimosis is the narrowing of the foreskin, epispadias is a congenital malformation of the penis, and orchiotomy refers to the surgical removal of a testicle.
2.
Benign prostatic hyperplasia is characterized by
Correct Answer
E. Overgrowth of glandular tissue
Explanation
Benign prostatic hyperplasia refers to the non-cancerous enlargement of the prostate gland. This condition is characterized by the overgrowth of glandular tissue within the prostate. It is not associated with adenocarcinoma of the prostate (a type of prostate cancer), hydrocele (a fluid-filled sac around the testicle), urinary incontinence (involuntary leakage of urine), or varicocele (enlarged veins in the scrotum). The overgrowth of glandular tissue in the prostate is the main feature of benign prostatic hyperplasia.
3.
Congenital condition of the male urethra
Correct Answer
A. Hypospadias
Explanation
Hypospadias is a congenital condition of the male urethra where the opening of the urethra is located on the underside of the penis instead of at the tip. This condition occurs due to abnormal development during fetal development. It can cause difficulties with urination and may require surgical correction. Hydrocele refers to the accumulation of fluid around the testicle, circumcision is the surgical removal of the foreskin, varicocele is the enlargement of veins within the scrotum, and phimosis is the inability to retract the foreskin. None of these conditions directly relate to the congenital condition of the male urethra known as hypospadias.
4.
A gland below the bladder and surrounding the urethra
Correct Answer
B. Prostate
Explanation
The correct answer is the prostate. The prostate is a gland located below the bladder and surrounding the urethra. It plays a crucial role in the male reproductive system by producing a fluid that helps nourish and transport sperm. The prostate also helps control the flow of urine by contracting and releasing to allow or restrict the passage of urine through the urethra.
5.
A spermolytic substance
Correct Answer
C. Destroys sperm cells
Explanation
The correct answer is "Destroys sperm cells." A spermolytic substance refers to a substance that is capable of destroying or killing sperm cells. This could be used as a form of contraception or as a treatment for certain conditions where the destruction of sperm cells is desired, such as in cases of male infertility.
6.
Orchiopexy
Correct Answer
D. Fixation of an undescended testicle
Explanation
Orchiopexy is the surgical procedure that involves fixing an undescended testicle. This procedure is performed to bring the testicle down into the scrotum and secure it in place. It is the correct answer because it accurately describes the surgical intervention for an undescended testicle, which is the fixation of the testicle in its proper position. The other options, such as removal of the prepuce, removal of a testicle, incision and removal of a piece of the vas deferens, and prolapse of a testicle, do not correspond to the correct procedure for an undescended testicle.
7.
Non-gonococcal urethritis is most often caused by
Correct Answer
E. Chlamydial infection
Explanation
Non-gonococcal urethritis is most often caused by chlamydial infection. Chlamydia trachomatis is a common sexually transmitted bacterial infection that can cause inflammation of the urethra. It is one of the leading causes of non-gonococcal urethritis, along with other bacteria such as Mycoplasma genitalium and Ureaplasma urealyticum. Prostatitis is inflammation of the prostate gland, castration is the removal of the testicles, herpes genitalis is a viral infection, and syphilis is a bacterial infection, none of which are the most common cause of non-gonococcal urethritis.
8.
Treating tissue with cold temperatures is called
Correct Answer
A. Cryogenic surgery
Explanation
Cryogenic surgery refers to the process of treating tissue with cold temperatures. This technique is used to freeze and destroy abnormal or diseased tissue, such as tumors. The extreme cold temperatures are achieved by using liquid nitrogen or other cryogenic substances. This freezing process helps to remove or kill the targeted tissue without causing significant damage to the surrounding healthy tissue. Cryogenic surgery is commonly used in various medical fields, including dermatology, gynecology, and oncology.
9.
Glands that secrete semen (Proper Spelling)
Correct Answer
B. Bulbourethral
Explanation
The correct answer is "bulbourethral." The glands that secrete semen are called bulbourethral glands. These glands are also known as Cowper's glands and are located below the prostate gland. They produce a clear fluid that helps to lubricate and neutralize the acidity of the urethra before ejaculation.
10.
Tubules that produce sperm (Proper Spelling)
Correct Answer
C. Seminiferous
Explanation
The correct answer is "seminiferous." This term refers to the tubules in the testes that are responsible for producing sperm. The spelling of "seminiferous" is appropriate in this context as it accurately describes the function and location of these tubules. The other options provided ("semeninferious," "semeniferious," "seminefarous," "semenifierous") do not exist or are misspelled, and therefore, they are incorrect.
11.
Tissue that produces sperm cells
Correct Answer
E. Seminiferous tubules
Explanation
Seminiferous tubules are the correct answer because they are the specific tissue within the testes that is responsible for producing sperm cells. These tubules are lined with cells called Sertoli cells, which support and nourish the developing sperm cells. Through a process called spermatogenesis, the seminiferous tubules produce mature sperm cells that are eventually released into the epididymis for storage and maturation. The other options listed, such as ureters, endometrium, urethra, and interstitial, are not involved in the production of sperm cells.
12.
Carcinoma of the testes (Proper Spelling)
Correct Answer
A. Embryonal
Explanation
The correct answer is "embryonal." Carcinoma of the testes refers to cancer that originates in the testicles. The term "embryonal" is used to describe a specific type of testicular carcinoma that resembles embryonic tissue. It is important to spell medical terms correctly to ensure accurate communication and understanding among healthcare professionals.
13.
Pus-filled (Proper Spelling)
Correct Answer
B. Purulent
Explanation
The correct answer is "purulent." This term is used to describe something that contains or produces pus. It is commonly used in medical contexts to describe infections or wounds that have a yellowish or greenish discharge. The other options listed are not proper spellings of the word and do not accurately convey the intended meaning.
14.
Hair-like tail region of the sperm is called
Correct Answer
C. Flagellum
Explanation
The hair-like tail region of the sperm is called the flagellum. The flagellum is responsible for the sperm's movement, propelling it forward in order to reach and fertilize the egg. It is a long, whip-like structure that contains microtubules and is covered by the cell membrane. The flagellum plays a crucial role in the process of sperm motility and is essential for successful fertilization.
15.
A chancre is the primary lesion in which of the following conditions
Correct Answer
A. SypHilis
Explanation
A chancre is the primary lesion in syphilis. Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. The chancre is a painless sore that appears at the site of infection, usually on the genitals, rectum, or mouth. It is the first sign of syphilis and typically appears within 3 weeks to 3 months after exposure. The presence of a chancre is characteristic of syphilis and distinguishes it from other conditions listed in the options, such as gonorrhea, genital herpes, non-gonococcal urethritis, and HIV.
