Where do somites develop from?
The somites (outdated term: primitive segments) are a set of bilaterally paired blocks of paraxial mesoderm that form in the embryonic stage of somitogenesis, along the head-to-tail axis in segmented animals.Click to see full answer.

The somites (outdated term: primitive segments) are a set of bilaterally paired blocks of paraxial mesoderm that form in the embryonic stage of somitogenesis, along the head-to-tail axis in segmented animals.Click to see full answer. Correspondingly, what do somites develop from?Somitogenesis. Formation of somites, metameric structures of the vertebrate embryo, represents a fundamental aspect of the vertebrate body segmentation. Somites arise from the presomitic mesoderm (PSM) and develop sequentially in rostral-caudal order.Beside above, what are somites in anatomy? Somites are transient structures that will give rise to cells of the vertebrae and ribs, dermis of the dorsum, skeletal muscle of the body wall, back and limbs. Somites begin to develop at the anterior of the embryo first, and appear at regular intervals. Likewise, what do somites formed from mesoderm during Somitogenesis go on to form? Somites give rise to many different connective tissues including: cartilage, bone, muscle and tendon. Cranial paraxial mesoderm remains unsegmented, and does not form somites, and will form the pharyngeal muscle progenitor field, the embryonic origin of facial and neck muscles.How is mesoderm formed?The mesoderm is one of the three germinal layers that appears in the third week of embryonic development. It is formed through a process called gastrulation. The lateral plate mesoderm give rise to the heart, blood vessels and blood cells of the circulatory system as well as to the mesodermal components of the limbs.
