Question

growth of the embryo is said to follow both a cephalocaudal and proximodistal pattern. what does this mean? fingers and toes tend to form early in development, with the central nervous system forming last. the head, upper body parts, and organs tend to form first, with extremities forming last. the body parts tend to form much earlier than internal organs. the rate at which body parts and organs develop depends on the health of the mother.

Explanation:

Cephalocaudal refers to growth from head - to - tail, and proximodistal refers to growth from the center of the body to the extremities. So, the head, upper body parts, and organs (near the head and center) form first, and extremities form last.

Answer:

The head, upper body parts, and organs tend to form first, with extremities forming last.
