QUESTION
The diameter of a mature corpus luteum, when compared with the diameter of a mature Graafian follicle in a cow is?
OPTIONS
(A) Larger
(B) Smaller
(C) Equal
(D) None of the above
ANSWER
(A) Larger
EXPLANATION
A mature bovine corpus luteum is generally larger in diameter than a mature preovulatory follicle because luteinization produces a substantial mass of highly vascular luteal tissue. A mature follicle is mostly a fluid-filled cavity surrounded by its wall. Smaller or equal does not represent the usual comparison, although individual measurements and atypical ovarian structures can overlap.
