Part of the skin that connects the epidermis and subcutaneous tissue and carries vessels and nerves. In addition to elastic fibres, collagen fibres are found in particular. The epidermal appendages (hair, sweat and sebaceous glands) are embedded in the dermis, which is divided into the following parts:
  • Stratum papillare: Loose connective tissue that lies between the epidermal reticular ridges.
  • Stratum reticulare: Deeper dermal layer that includes abundant Type I collagenous fibres. These are arranged in an angular arrangement and allow the skin to stretch. The abundance of collagen fibres leads to recovery.
