layers of the integumentary system
Layers of The integumentary system
  • Epidermis
  • Dermis
  • Hypodermis
epidermis
Epidermis
  • The top layer of skin made up of the epithelial cells.
  • Does not contain blood vessels.
  • Its main function is protection, absorption of nutrients, and homeostasis.
  • Its structure consists of a keratinized stratifies squamous epithelium which is made of four types of cells. Keratinocytes, melanocytes, merkel cells, and langerhans’ cells.
dermis
Dermis
  • The dermis is the middle layer of skin
  • Composed of dense irregular connective tissue and areolar connective tissue such as collagen.
  • The dermis has two layers
  • One is a papillary layer
  • The other is a reticular layer
  • The dermal layers provide a site for the endings of blood vessels and nerves
hypodermis
Hypodermis
  • Also called hypoderm, subcutaneous tissue, or superficial fascia and the bottom layer of the integumentary system.
  • Types of cells that are found in the hypodermis are fibroblasts, adipose cells, and macrophages.
  • It is derived from the mesoderm, but not the dermatome region of the mesoderm
