A myotome is the group of muscles that a single spinal nerve innervates. [1] Similarly a dermatome is an area of skin that a single nerve innervates with sensory fibers. Myotomes are separated by myosepta (singular: myoseptum). [2] In vertebrate embryonic development, a myotome is the part of a somite that develops into muscle.
The myotome is that part of a somite that forms the muscles of the animal. [2] Each myotome divides into an epaxial part (epimere), at the back, and a hypaxial part (hypomere) at the front. [2] The myoblasts from the hypaxial division form the muscles of the thoracic and anterior abdominal walls.
Myotome is the group of muscles that a single spinal nerve root innervates. Myotome may also refer to: Myotome (embryology) , part of a somite that forms the muscles of the animal
In somitogenesis, somites form from the paraxial mesoderm, a particular region of mesoderm in the neurulating embryo.This tissue undergoes convergent extension as the primitive streak regresses, or as the embryo gastrulates.
The first seven somitomeres give rise to the striated muscles of the face, jaws, and throat. [2]The remaining somitomeres, likely driven by periodic expression of the hairy gene, begin expressing adhesion proteins such as N-cadherin and fibronectin, compact, and bud off forming somites.
Notochord is positioned just ventral to the neural tube and dorsal to the gut, flanked by myotome. (D) Notochord homolog in annelid. Cross-section showing the position of the proposed axochord to the ventral mesentery, blood vessel, and nerve chord.
Myogenesis is the formation of skeletal muscular tissue, particularly during embryonic development.. Myoblasts (cells with a single nucleus, represented in violet) fusing together to form muscle fibers (multinucleated muscle cells) during myogenesis
PDF's emphasis on preserving the visual appearance of documents across different software and hardware platforms poses challenges to the conversion of PDF documents to other file formats and the targeted extraction of information, such as text, images, tables, bibliographic information, and document metadata. Numerous tools and source code ...
