The somites (outdated term: primitive segments) are a set of bilaterally paired blocks of paraxial mesoderm that form in the embryonic stage of somitogenesis, along the head-to-tail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 …

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. …

Jul 25, 2025 · Somites are temporary, segmented blocks of tissue that form during the early embryonic development of vertebrates. These structures are derived from the mesoderm, …

Oct 20, 2010 · The process of somite formation, or somitogenesis, depends on five important components: periodicity, fissure formation, epithelialization, specification, and differentiation. …

A somite is added either side of the notochord (axial mesoderm) to form a somite pair. The segmentation does not occur in the head region, and begins cranially (head end) and extends …

somite: One of the paired masses of mesoderm, distributed along the sides of the neural tube, that will eventually become dermis, skeletal muscle, or vertebrae.

The meaning of SOMITE is one of the longitudinal series of segments into which the body of many animals is divided : metamere.

In the chick, one somite forms every 90 minutes or so; this varies somewhat among different vertebrates: faster in teleost and anuran amphibian embryos and slower in most mammals.

Somites are bilaterally paired blocks of paraxial mesoderm that form along the anterior-posterior axis of the developing embryo in vertebrates. The somites give rise to skeletal muscle, …

Somites are blocks of mesodermal tissue found in the developing embryo that play a crucial role in the formation of the vertebral column, muscles, and skin.
