Question

Where does the Tyson's glands occur in the male reproductive system?
A. Urethra
B. Scrotal sac
C. Prepuce
D. Corona of glans

Answer 1

The penis is one of the supporting structures of the male reproductive system. The tip of the penis is covered with loose folds of skin. The skin houses modified sebaceous glands.

Complete answer:
Male reproductive system consists of a pair of testes, ducts, accessory glands, and supporting structures.
Testes are the primary sex organs of males. During embryonic development, testes descend from the abdomen to the scrotal sac or scrotum. The scrotal sac is a pouch of skin that provides the temperature lower than that of the body to the testes as required for sperm production.

Sperms are formed by the process of spermatogenesis in the seminiferous tubules of the testes. From the testes, sperms are transported to epididymis through vasa efferentia. Sperms are stored and matured in the epididymis and are then delivered to the vas deferens. The terminal part of the vas deferens and the duct from the seminal vesicle join to form an ejaculatory duct. From the ejaculatory duct, sperms and the secretion of the seminal vesicle are carried to the urethra. The urethra is the long duct that extends from the urinary bladder to the penis. It serves as a passage for the transport of semen and urine.

The urethra opens into the penis at the urethral meatus. The penis is the passageway for the release of semen and urine from the body. The distal end of the penis is called the glans penis. The margin of the glans penis is called the corona. Glans penis is covered with a loosely fitting foreskin. The foreskin of the penis is also called the prepuce. Prepuce houses Tyson's glands which serve to secrete a yellowish-white liquid called smegma. Tyson's glands are the sebaceous glands and their secretion consists of dead skin cells and sebum.

Hence, the correct answer is option (C).

Note: Sebaceous glands are one of the glands of the skin and secrete the oily substance called sebum. They are present in the genitalia of both males and females. Tyson's glands are also called preputial glands due to their presence in the prepuce.
