- Somite - Wikipedia
The somites (outdated term: primitive segments) are a set of bilaterally paired blocks of paraxial mesoderm that form in the embryonic stage of somitogenesis, along the head-to-tail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
- Somites: Formation and Role in Developing the Body Plan
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, cartilage, tendons, and vertebrae Somites also determine the migratory paths of neural crest cells and of the axons of spinal nerves
- Somite | Vertebrate Embryo, Segmentation Mesoderm | Britannica
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
- Somitogenesis - Embryology
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 In humans, the first somite pair appears at day 20 and adds caudally at 1 somite pair 90 minutes until on average 44 pairs eventually form
- Paraxial Mesoderm: The Somites and Their Derivatives
As the primitive streak regresses and the neural folds begin to gather at the center of the embryo, the paraxial mesoderm separates into blocks of cells called somites Although somites are transient structures, they are extremely important in organizing the segmental pattern of vertebrate embryos
- Multiple roles of timing in somite formation - PMC
During development of vertebrate embryos, a series of repeated elements, called somites, is laid down on either side of the main axis of the body (neural tube and notochord) (for reviews see [1 – 4]
- 27. 4C: Somite Development - Medicine LibreTexts
In the developing vertebrate embryo, somites are masses of mesoderm that can be found distributed along the two sides of the neural tube They will eventually become dermis (dermatome), skeletal muscle (myotome), vertebrae (sclerotome), and tendons and cartilage (syndetome)
- Periodic formation of epithelial somites from human . . . - Nature
Here, we report the generation of human somitoids, organoids that periodically form pairs of epithelial somite-like structures
