Draw and label the structure of a human ovum.

Explanation

• Ovaries are the primary female sex organ producing eggs (ovum).
• They are located one on each side of lower abdomen (pelvis).
• The ovary is attached in pelvic wall uterus by an ovarian ligament called mesovarium.
• It is an elliptical structure of 2-4 cm long
• Each ovary is covered by thin cuboidal germinal epithelium encloses ovarian stroma.
• Below germinal epithelium is a dense connective tissue called tunica albuginea.
`*` The stroma is differentiated into outer cortex and inner medulla.
• The cortex is dense and granular due to follicular cells at varying development stages.
• The medulla is a loose connective tissue with blood vessels, lymph vessels and nerve fibres.
