Paraxial mesoderm
Paraxial Mesoderm
Paraxial mesoderm (pronunciation: /pærˈæksɪəl ˈmɛzədɜːrm/) is a type of mesoderm that is located along the sides of the neural tube in an embryo. It is one of the three primary germ layers, the others being the ectoderm and endoderm.
Etymology
The term "paraxial mesoderm" is derived from the Greek words "para" meaning beside, "axial" referring to the axis or central line, and "mesoderm" which is the middle layer of an embryo from which various tissues and organs develop.
Function
The paraxial mesoderm gives rise to a series of blocks of tissue called somites. These somites further differentiate into dermatome, myotome, and sclerotome, which form the skin, skeletal muscle, and vertebral column respectively.
