16
Q

Two Layers of the Dermis

A

Papillary Layer and Reticular Layer

17
Q

Papillary Layer

A

Composed of a thin sheet of of areolar connective tissue that’s riddled with peg-like projections called dermal papillae.

18
Q

Dermal Papillae

A

Tiny protrusions in the thick layer of skin that from unique ridges that press up through the epidermis to help hands and feet grip surfaces.

19
Q

Reticular Layer

A

Made up of dense irregular connective tissue that holds all the dynamic parts of the dermis.

20
Q

Hypodermis (Subcutis)
