Development of the Reproductive System

Where is the Primordial Germ Cells develop in week two?

• Epiblast

• Hypoblast

• Trophoblast

• Gonadal ridge

How is the gonadal ridge develop?

• It is a thickened area of the mesodermal epithelium

• It comes from the mesonephros

• It comes from the Primordial Germ Cells

• It comes from the yolk sac

How is the primary sex cords develops?

• From primordial germ cells

• From the mesenchyme epithelium of the posterior abdominal wall

• Primordial germ cells invades the mesenchyme epithelium of the posterior abdominal wall

• Primordial germ cells grow in the gonadal ridge

Which of the following factors determines the sex of the embryo?

• Primary sex cords

• Cortex

• Medulla

• TDF

The prostatic utricle is a remnant of:

• the degenerated paramesonephric duct

• the mesonephric duct

• the retee testes

• the primary sex cords

Which factor inhibits the paramesonephric duct?

• Testosterone

• Mullerian inhibiting Factor

• Hormones secreted by the Leydig cells

• Growth of the mesonephric ducts.

Paramesonephric duct (Mullerian duct) helps in the development of;

• Uterine tube, uterus, and vagina

• Epididymis, vas deference, and ejaculatory duct

• Urethra

• Gubernaculum

What is the gubernaculum testis?

• It is mesenchymal cord

• It attaches to the scrotum

• It guides the testis to the scrotum

• It attaches to the poles of the testis

What is the Processus vaginalis?

• An outpouching of peritoneum helps in descend of the testis

• It is a permanent layer surround the testis

• Important in testicular development

• One of the contents of the spermatic cord.

Patent processus vaginalis leads to;

• Complete inguinal hernia

• Undescended testis

• Hypospadius

• Sterility
