Question

Quizplus · Accepted Answer

The process needed to define each of the toes and fingers is programmed cell death, also known as apoptosis. This is because during development, cells between the fingers and toes undergo apoptosis, leading to the separation of the digits. Without programmed cell death, the fetus would be born with webbed fingers or toes. Neurulation refers to the formation of the neural tube, gastrulation refers to the formation of the three germ layers, and induction refers to the process by which one group of cells influences the development of another group of cells. None of these processes specifically relate to the formation of distinct fingers and toes.
