Mesodermal

Mesodermal (pronunciation: /ˌmɛsəʊˈdɜːməl/) is a term used in Embryology to describe one of the three primary germ layers in the very early embryo. The other two layers are the ectoderm and endoderm, with the mesoderm being the middle layer.

Etymology

The term "mesodermal" is derived from the Greek words "mesos" meaning middle, and "derma" meaning skin. This is reflective of its position in the developing embryo.

Function

The mesodermal layer forms a variety of tissues and structures in the body, including the heart, blood, blood vessels, skeletal muscles, smooth muscles, bones, cartilage, connective tissue, adipose tissue, lymphatic system, reproductive system, and the kidneys and ureters.
