Second Layer of skin consisting of various connective tissues.
Function of the Dermis:
Provides strength, extensibility (stretchability), elasticity (ability to return to original form).
Two Layers of the Dermis:
Papillary Layer, Reticular Layer
A thin, outer layer of the dermis with finger like projections called dermal papillae that protrude into the epidermis. The dermal papillae create epidermal ridges, which are responsible for finger prints.
Thick layer, below the papillary layer, that makes up most of the dermis
Hypodermis (Subcutaneous Layer):
Layer between the dermis and underlying tissues and organs. Storage site for most body fat.
Functions of the Hypodermis:
Thermal Insulation, Shock Absorption, fastens skin to underlying surface
