The somites (outdated term: primitive segments) are a set of bilaterally paired blocks of paraxial mesoderm that form in the embryonic stage of somitogenesis, along the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

Oct 20, 2010 · Somites are precursor populations of cells that give rise to important structures associated with the vertebrate body plan and will eventually differentiate into dermis, skeletal muscle, …

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, specifically the …

Nov 24, 2025 · Somites are blocks of mesodermal tissue that serve as the foundational structures for the segmented body plan of vertebrates. These transient embryonic structures are paired masses of …

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 …

At about 20 days of gestation, the paraxial mesoderm divides into paired cuboidal structures called somites. These somites are located laterally on both sides of the developing neural tube. The first …

The term somitogenesis is used to describe the process of segmentation of the paraxial mesoderm within the trilaminar embryo body to form pairs of somites, or balls of mesoderm.

Alongside the neural tube, the mesoderm develops distinct paired structures called somites that develop into dermis, skeletal muscle, and vertebrae. Each somite has four compartments: the sclerotome, …

During development, vertebrate embryos produce serially repeated elements, the somites, on each side of the midline. These generate the vertebral column, skeletal musculature and dermis.

Feb 28, 2024 · This metameric organization is first implemented by somitogenesis in the early embryo, when paired epithelial blocks called somites are rhythmically formed to flank the neural tube.
