Paraxial mesoderm

Paraxial mesoderm is the area of mesoderm that forms just lateral to the neural tube on both sides.

It gives rise to the somitomeres/somites and mesoderm of the branchial arches.


 * Somites form the vertebral column dermis and skeletal muscle
 * Branchial arches will develop into facial muscle and cartilage, plus other structures.

the caudal region. pharyngeal arches approxiamtely 20 days.
 * eventually differentiates into the axial skeleton, skeletal muscle, part of the dermis
 * almost immediately as it is formed, somitomeres develop.
 * starts with several pairs in the cranial region, and increasingly more proceed to develop towards
 * The original seven pairs form the straited muscles of head and neck, which develop within the
 * The other somitomeres develop further, to form discrete blocks called somites, starting at
