Expert Solution & Answer

Answer to Problem 1PL

Correct answer:

The correct answer is an option (b) Development of the embryo and fetus progresses from cephalic toward caudal.

Explanation of Solution

Explanation/justification for the correct answer:

Option (b) cephalic is an embryo head. Caudal is an embryo tail. During the gastrulation period, the development starts from the head and ends with tail and orientation from front to back occurs. So, the correct answer is an option (b).

Explanation for incorrect answer:

Option (a) Development of the embryo and fetus progresses from medial toward lateral. The development of an embryo always occurs from head to tail not from medial to lateral. So, this is an incorrect option.

Option (c) Development of the embryo and fetus progresses from anterior toward posterior. The development of a fetus always starts from head to tail and front to back. So, this is an incorrect answer.

Option (d) Development of the embryo and fetus progresses from inferior toward a superior. The development occurs from head to tail not from inferior toward a superior.
