Skin Anatomy

The Skin in primarily made of three layers.

The upper layer is the Epidermis, and the layer below the Epidermis is the Dermis, and the third and deepest layer is the subcutaneous tissue. Skin is the bodies largest organ. It is made of water, protein, fats and minerals

The Epidermis

• The epidermis is the outermost layer of the skin. There are Five layers of cells in the Epidermis. The outermost is called The Stratum Corneum or (The Horny Layer).
• The second outermost layer is called the Stratum Lucidum/Clear Layer (only found in the palms of the hands and on the soles of the feet).
• The Middle/Third layer is Startum Granulosum/Granular Layer.
• The Fourth layer is called the Stratum Spinosum/Prickle Cell Layer.
• The Fife and final Layer is called the Stratum Basale/Basal or Germinative Layer.

The Dermis

• The Dermis is a tough and elastic layer containing white fibrous tissue interlaced with yellow elastic fibres.
• The Dermis is an expanse layer and contains:
• Blood Vessels
• Lymphatic Capillaries and Vessels
• Seat glands and their Ducts
• Subaceous Glands
• Sensory Nerve Endings

The deepest part of the skin closest to the muscle is called the subcutaneous tissue. The superficial fascia, hypodermis, subcutis, and tela subcutanea are other names for this layer. 

The epidermis, dermis, and hypodermis are the three layers that make up the skin. The hypodermis, or subcutaneous layer, is the innermost layer and the epidermis is the outermost layer. 

Most of the subcutaneous layer is made up of fat. The body's fat creates a layer that protects the organs from injury and acts as insulation against the cold. Additionally, it gives the skin structural support.
