Neurulation is the development of the nervous system from the
a) mesoderm.
b) hypoderm.
c) ectoderm.
d) endoderm.

The correct option is: C) ectoderm

Explanation:

In the embryos of vertebrates, neurulation is a folding process by which neural plate transforms into neural tube. In this process, the notochord signals the ectoderm germ layer to form a neutral plate, which folds in upon itself and leads to the formation of a neural tube. This neural tube then differentiates into brain and the spinal cord, thus forming the central nervous system.  

between the two muscle layers is the myenteric or auerbach's plexus, which controls peristalsis. in the colon, the muscularis externa is much thicker because the feces are large and heavy, requiring more force to push along. the stomach has a third layer of muscularis externa: the inner oblique layer.

answer: the choice of providing direction for individualized care of a patient.   the care plans is a flow of communication and organizing the constantly changing of the care plan.
