Connect the IS to the nervous system?

Skin detects stimuli. Stimuli is processed by the NS.

The dermis has several items that live there.  List 1 function of any two structures here.

thermoregulation

reduce friction

fight bacteria

This structure is made of sheets of hardened keratinocytes in order to provide protection to a distal end

Know why this is important

There are two ways the the skin regulates heat.  Describe 1 of them

Heat is transported to the skin's surface via the blood stream.  Sweat is produce in the dermis, and transferred to the skin.  Heat from the skin is transferred to the sweat.  Sweat evaporates.

Blood vessels constrict.  Heat is kept away from the surface, warming deeper structures.  Arrector pili muscles stand.

These structures are responsible for lubricating the skin against friction as well as having antibacterial assistance

sebaceous glands
