Question

2 weeks (Begins in week 3 and continues for almost 2 weeks, ending just before the closure of the caudal neural tube.)

Answer 1

Neurulation is the process in which the embryo develops structures that will eventually become the nervous system, including the spinal cord and brain. It occurs during weeks three and four after fertilization. Neurulation is a crucial step in the development of the central nervous system.

Step-by-step explanation:

Neurulation is the process in which the embryo develops structures that will eventually become the nervous system, including the spinal cord and brain. It occurs during weeks three and four after fertilization and starts with the formation of a structure called the neural plate. This plate then folds inward to form the neural tube, which will later develop into the spinal cord and brain. Neurulation is a crucial step in the development of the central nervous system.
