Question
Chapter 42.4, Problem 2R
Summary Introduction
To review:
The role of granulosa and thecal cells in the ovarian cycle, and the mechanism by which they limit the ovulated eggs’ numbers.
Introduction:
Ovarian cycle basically governs the preparation of the endocrine tissues and production of eggs, whereas menstrual cycle governs the preparation and regulation of the uterine lining. Both the cycles occur concurrently and are coordinated about 22 to 23 day cycle along with the length of 28 days.
