!Skin - Overview
!!Anatomy
The skin is the largest organ of the integumentary system. It is made up of several layers of ecto- and mesodermal tissue, and guards the underlying ((Musculoskeletal - Skeletal Muscles|muscles)), ((Musculoskeletal - Bones|bones)), ((Musculoskeletal - Connective Tissue|ligaments)) and internal organs.The skin __interfaces with the environment__ and thus __protects__ from external factors. It plays a key role in protecting against drying out, in insulation, temperature regulation, sensation, and the production of vitamin D folates. 

Severely damaged skin may heal by forming scar tissue, which can then show discolouration and depigmentation. The thickness of skin also varies in different locations: the skin located under the eyes and around the eyelids is the thinnest skin in the body at 0.5 mm thick, and is one of the first areas to show signs of aging such as "crows feet" and wrinkles. The skin on the palms and the soles of the feet is 4 mm thick and the thickest skin in the body. All mammals have some hair on their skin, even marine mammals which appear to be hairless.

!!!Association Areas
Skin affections have conflict themes according to their locality. This can be directly connected to the place where the conflict - e g attack or loss of touch - is experienced, or connected to these associations:
