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.
