5
Q
Somatic nervous system
A
Sensory and motor neurons distributed throughout skin, joints, and muscles; sensory neurons transmit info through afferent fibers; motor impulses travel along efferent fibers

26
Development of nervous system
Neurulation at 3-4 weeks:
- ectoderm overlying notochord begins to furrow, forming neural groove surrounded by 2 neural folds
- Cells at edge of neural fold = neural crest
- furrow closes to form neural tube, which will form the CNS
- Neural tube has alar plate which differentiates into sensory neurons and basal plate which differentiates into motor neurons
