Transcript

  • 1. Anatomy and physiology Skin Beauty Therapy S/NVQ Level 2 Skin The dermis, subcutaneous layer and appendages of the skin
  • 2. Anatomy and physiology Skin Beauty Therapy S/NVQ Level 2 The dermis, subcutaneous layer and appendages of the skin 3 Subcutaneous layer 1 Dermis (true skin) 2 Reticular layer
  • 3. Anatomy and physiology Skin Beauty Therapy S/NVQ Level 2 The dermis, subcutaneous layer and appendages of the skin: Dermis • The dermis is sometimes referred to as the true skin. • It varies in thickness depending on the location of the skin. It is 0.3mm on the eyelid and 3.0mm on the back.
  • 4. Anatomy and physiology Skin Beauty Therapy S/NVQ Level 2 The dermis, subcutaneous layer and appendages of the skin: Dermis • The dermis contains many structures. • It consists of two layers: • papillary layer • reticular layer.
  • 5. Anatomy and physiology Skin Beauty Therapy S/NVQ Level 2 The dermis, subcutaneous layer and appendages of the skin: Papillary layer • The papillary layer is a wavy layer of tissue. • It contains lots of blood and lymph vessels, which feed the epidermis to allow for cell reproduction and remove waste. • It contains lots of nerve endings, which allow you to feel sensations. • It joins the epidermis to the dermis.
  • 6. Anatomy and physiology Skin Beauty Therapy S/NVQ Level 2 The dermis, subcutaneous layer and appendages of the skin: Reticular layer • The reticular layer is a dense, fibrous tissue. • It is beneath the papillary layer. • It contains the main components of the dermis: • collagen tissue • elastin tissue • reticulin tissue. • It protects and repairs injured tissue.
  • 7. Anatomy and physiology Skin Beauty Therapy S/NVQ Level 2 The dermis, subcutaneous layer and appendages of the skin: Subcutaneous tissue • The subcutaneous tissue is a fatty layer underneath the skin (sub = under; cutaneous = of the skin). • The fat cells store energy (fat). • This tissue protects the underlying structures from damage. • It provides a layer of insulation for warmth. • It provides an energy store should the body need it.
  • 8. Anatomy and physiology Skin Beauty Therapy S/NVQ Level 2 The dermis, subcutaneous layer and appendages of the skin: Can you label the layers? 3 Subcutaneous layer 1 Dermis (true skin) 2 Reticular layer
