The somites (outdated term: primitive segments) are a set of bilaterally paired blocks of paraxial mesoderm that form in the embryonic stage of somitogenesis...

for somite differentiation Notochord protein accumulates in presomitic mesoderm destined to form the next somite and then decreases as that somite is established...

Somitogenesis is the process by which somites form. Somites are bilaterally paired blocks of paraxial mesoderm that form along the anterior-posterior...

is established during embryogenesis when somites are rhythmically added to the posterior of the embryo. Somite formation begins around the third week when...

the ocular somite (referred as "acron" in previous literatures), which carries the eyes and labrum, with six post-ocular segments (somite 1 to 6), which...

ectoderm and somite-forming morphogenic factors cause some primary mesenchyme to form neural mesenchyme, or paraxial mesoderm, and contribute to somite formation...

simultaneously with the neural tube. The cells of this region give rise to somites, blocks of tissue running along both sides of the neural tube, which form...

myoseptum). In vertebrate embryonic development, a myotome is the part of a somite that develops into muscle. The anatomical term myotome which describes the...

which somites, blocks of mesoderm that give rise to a variety of connective tissues, are formed. The model describes the splitting off of somites from...

embryo's length into somites, corresponding to the segmentation of the body (most obviously seen in the vertebral column. Each somite has three divisions...
