Craniofacial Muscle Development
2015The developmental mechanisms that control head muscle formation are distinct from those that operate in the trunk. Head and neck muscles derive from various mesoderm populations in the embryo and are regulated by distinct transcription factors and signaling molecules.

Fetal development of the pyloric muscle
Surgical and Radiologic Anatomy, 1992The fetal development of the pyloric muscle was studied in five human embryos (crown-rump length 5 to 31 mm) and in ten fetuses aged 3 to 9 months. Samples of pyloric muscle were obtained during operation for pyloric stenosis in two infants aged six weeks.

A community effect in muscle development
Current Biology, 1993Most vertebrate tissues arise by embryonic induction, as a result of which new cell layers are formed. These are subsequently subdivided into discrete groups of homogeneous cell populations, each containing different cell-types with specific gene expression.

Development of the anal canal muscles
Diseases of the Colon & Rectum, 1991The anal canal muscles development is studied in 18 human embryos. The external anal sphincter results to origin common with the urogenital sphincter from the cloacal sphincter. The muscle, after its appearance, is subdivided into two portions from a thin mesenchymal layer.

The developmental paths that lead to the formation of skeletal muscles in the head are distinct from those operating in the trunk. Craniofacial muscles are associated with head and neck structures. In the embryo, these structures derive from distinct mesoderm populations. Distinct genetic programs regulate different groups of muscles within the head to

Cadherins in Skeletal Muscle Development
2002One essential step in the complex process of myogenesis is the fusion of mononuclear myoblast cells into polynuclear myotubes. This fusion process is promoted by cadherins, a multigene family of transmembrane cell adhesion glycoproteins that mediate homophilic interactions in a calcium-dependent manner, thus selectively associating cells into specific ...

Regulation of hypaxial muscle development
Cell and Tissue Research, 1999The majority of skeletal muscles in higher vertebrates are hypaxial and stem from the lateral lip of the dermomyotomes. Various external signals converge on the dorsolateral quadrant of the somite to specify the hypaxial muscle precursors, to discriminate between migratory and non-migratory cells and to allow delamination of precursors destined for ...

1974
In recent years interest in muscle development has increased considerably. One reason for this is that muscle affords a good example of tissue differentiation and growth, in that it is a tissue that is apparently programmed to produce considerable quantities of rather specialized proteins in order to carry out its contractile function. Muscle therefore

Skeletal muscle development in normal and double‐muscled cattle
The Anatomical Record Part A: Discoveries in Molecular, Cellular, and Evolutionary Biology, 2004AbstractThis study examined the effect of genotype on prenatal muscle development in both normal‐muscled (NM) animals and in double‐muscled (DM) animals harboring a mutation in the gene for myostatin that results in the production of a functionally inactive protein.

Muscle Coordination and the Development of Musculoskeletal Disorders
Exercise and Sport Sciences Reviews, 2017The present article examines the hypothesis that each individual has unique muscle coordination strategies (or signatures) that will have specific mechanical effects on their musculoskeletal system. As such, some strategies would make some people more at risk of developing musculoskeletal disorders than others. Identification of individual coordination
