Somite, in embryology, one of a longitudinal series of blocklike segments into which the mesoderm, the middle layer of tissue, on either side of the embryonic spine becomes divided. Collectively, the somites constitute the vertebral plate. Out of the somites arise the sclerotome, forerunner of the

Somit je dio tijela životinje ili njenog embriona.. Somiti su bilateralno upareni blokovi paraaksijalnog mezoderma koji se oblikuju duž osi od glave do repa u razvoju embriona u segmentiranih životinja. Somites are epithelial blocks of paraxial mesoderm that define the vertebrate embryonic segments. They are responsible for imposing the metameric pattern observed in many tissues of the adult such as the vertebrae, and they give rise to most of the axial skeleton and skeletal muscles of the trunk.

In vertebrates, somites subdivide into the sclerotomes, … Somite definition, any of the longitudinal series of segments or parts into which the body of certain animals is divided; a metamere. See more. The tissue that immigrates via the primitive streak and initially forms the third germinal layer, the mesoderm, transforms itself several times.The epiblast-epithelial (ectoderm cells) are transformed into segmented mesoderm cells.In contrast to the epithelial cells, these are loosely organized. A new transformation follows, i.e., an epithelialization to become somites, which represent an A somite is a division of the body of an animal or embryo.. Somites are bilaterally paired blocks of paraxial mesoderm that form along the head to tail axis of the developing embryo in segmented animals. In vertebrates, somites give rise to the vertebrae of the spine, rib cage, (and part of the occipital bone); skeletal muscle, cartilage, tendons, and skin.
