Abdominal skin/histological specimen


Abdominal skin belongs to the so-called thick type of skin.

Layers

Epidermis

The epidermis (skin) consists of stratified squamous epithelium with cornification. It regularly runs into the dermis layer and thus creates epidermal ridges . On the cross-section, we distinguish five layers: str. basale , stratum spinosum , str. granulosum , str. lucidum and str. corneum (for a more detailed description, see the article Thick skin).

Dermis

The dermis (Slovak suede, Czech skára) develops from the mesenchyme and consists of ligaments that strengthen the epidermis. In some places, it runs into the epidermis and thus creates dermal papillae . It consists of two layers:

  • pp. reticulare: dense tissue;
  • pp. papillare: thin ligament.

Hypodermis

The hypodermis (subcutaneous tissue) consists of thin tissue, adipocytes, sweat glands (eccrine – simple coiled tubular glands opening onto the surface of the skin, basally surrounded by myoepithelial cells).
