Gives rise to	dermis

The cutis plate is the dorsal portion of the paraxial mesoderm somite which gives rise to dermis.

It is also known as the "dermatome", but it should not be confused with the dermatomic area, which is also sometimes called a "dermotome". (The two concepts are related, but the cutis plate is an embryological structure, while the dermatomic area is present in the adult.)
