Question

(a) Name and explain the role of inner and middle walls of the human female uterus.
(b) Write the location and function of fimbriae in human female.

Hint:

Endometrium supports implantation, while myometrium helps in uterine contractions. Fimbriae assist in ovum pickup and transport toward the fallopian tube.

Answer 1

Step 1 (a): The inner and middle walls of the uterus are:

• Endometrium (Inner lining): It undergoes cyclic changes during the menstrual cycle and is essential for implantation of the embryo. It provides nourishment to the developing embryo.
• Myometrium (Middle muscular layer): It consists of smooth muscle fibers that help in the contraction of the uterus during childbirth and menstrual flow.

Step 2 (b):

• Location of fimbriae: Fimbriae are finger-like projections present at the distal end of the fallopian tubes near the ovary.
• Function: They help in capturing the ovum released from the ovary and direct it into the fallopian tube.
