Dermomyotome
Dermomyotome (pronunciation: der-mo-my-o-tome) is a term used in Embryology to describe a structure that develops from the Paraxial mesoderm during the early stages of Embryonic development.
Etymology
The term 'Dermomyotome' is derived from the Greek words 'derma' meaning skin, 'myo' meaning muscle, and 'tome' meaning a cutting or section.
Definition
A Dermomyotome is a group of Mesenchymal cells that differentiate into the Dermis of the skin and the skeletal muscles of the back, ribs, and limbs. It is a part of the Somite, which is a transient structure formed during the segmentation of the paraxial mesoderm.
Development
During embryonic development, the paraxial mesoderm divides into somites, each of which further differentiates into a Sclerotome and a Dermatome. The Dermomyotome develops from the dorsal part of the somite and gives rise to the dermis and skeletal muscles.
