Histology Testbank: Male Reproductive System 1a
Instructions: For each histology question, pick the one best answer. This histology test bank is also useful for the histology questions on the USMLE (USMLE step 1).
Leydig cells produce testosterone. These are also called "interstitial cells" or "interstitial cells of Leydig". Sertoli cells are directly involved in spermatogenesis. They are also called "sustentacular cells" or "nurse cells".
The average testis in an adult man has between 400 and 600 seminiferous tubules.
Sertoli cells produce inhibin and androgen-binding protein. The interstitial cells of Leydig produce testosterone.
The male genital duct system contains: rete testes, tubuli recti, ductuli efferentes, ductus epididymidis, and ductus deferens. The male accessory glands contain the bulbourethral glands, seminal vesicles, and prostate.
Microvilli are the finger like projections seen on the surface of some cells. The appearance of microvilli form what is also called the brush border or striated border.
Stereocilia are very long microvilli. Stereocilia are seen in the epididymis and the hair cells of the ear.
Cilia is the hair like surface modification seen on some epithelia. Cilia are made of microtubules.
Keratinization is seen in the epidermis. Cells in the stratum corneum are essentially just bags of keratin.
Hormones can have a variety of structures. Hormones which are proteins include insulin and prolactin. Peptide chains are short chains of amino acids. Examples of hormones which are peptide chains are antidiuretic hormone and oxytocin. Steroid hormones are cholesterol derivatives. Steroid hormones include testosterone and estradiol. Norepinephrine and epinephrine are catecholamines.
The corpora cavernosa and corpus spongiosum are erectile tissue. There are two corpora cavernosa and one corpus spongiosum.
The prostate gland is found in males.
Skene's glands are also called the lesser vestibular glands and are found in females.
The bulbourethral glands are also called Cowper's glands. The bulbourethral glands are found in males and are homologous to the Bartholin's glands in females.
Brunner's glands are found in the duodenum.
The glandular epithelium of the prostate is most often simple columnar, however a variety of types can be found.
Pseudostratified epithelium lines the epididymis.
