MCQ – 84687

Correct Answer » B Explanation

Correct Answer:
– Neural crest cells give rise to the peripheral neurons and Schwann cells of the branchial arches.
– They are essential for the development of the cranial nerves associated with the arches, which are integral to their function.

Incorrect Options:
A. Neuroectoderm – Develops into the central nervous system and retina, not branchial arch nerves.
C. Mesoderm – Forms the musculoskeletal system and connective tissue components of the arches, not their nerves.
D. Endoderm – Develops into internal organ linings and structures, not nervous tissue.

High-Yield:
– Neural crest cells differentiate into a diverse array of structures, including peripheral nerves and cranial nerve ganglia.
– They are pluripotent, contributing to both neuronal and non-neuronal tissues in the developing embryo.
