Answer to Question 1

Ans:
B, D

Feedback:

Woven bone, often referred to as bundle bone, is deposited more rapidly than lamellar bone. It is of low tensile strength, serving as temporary scaffolding for support. It is found in developing fetus, in areas surrounding tumors and infections, and as part of a healing fracture.

Answer to Question 2

Ans:
A

Feedback:

Fertilization is followed by the release of human chorionic gonadotropin. The corpus luteum, not primary follicles, provides hormonal support for early pregnancy. The atrophy of corpus luteum and its replacement by corpus albicans only occur when fertilization does not take place. The endometrium will be preserved following fertilization.
