Question
Write a short note on uterus.

Answer

Uterus (Womb):
  • It is a single, hollow, muscular, pear-shaped structure supported by ligaments and attached to the pelvic wall.
  • It is present between the urinary bladder and the rectum.
  • The lower part of the uterus is very narrow and is called cervix. The cavity of the cervix is called cervical canal, which forms the birth canal along with vagina.
  • The wall of the uterus has three layers of tissue:
  • Perimetrium: Outer, thin covering of the uterus wall.
  • Myometrium: Middle, thick layer of smooth muscle fibres which contracts strongly during delivery of the baby.
  • Endometrium: Inner layer, that contains glands and many blood vessels. It undergoes cyclical changes during the menstrual cycle.
