GENERAL HISTOLOGY

Detailed explanation-1: -These two embryonic layers-ectoderm and mesoderm-ultimately give rise to the adult skin; the ectoderm produces the epidermis and its derivatives, and the mesoderm produces the dermis. The human fetus, at least, produces a specialized temporary embryonic skin, known as the periderm.

Detailed explanation-2: -Cells of mesodermal origin are the most abundant in the human body, representing a great variety of cell types, including the musculoskeletal system (bone, cartilage and muscle), cardiovascular system (heart, blood and blood vessels), as well as the connective tissues found throughout our bodies.
