Histology Terminology

Skin

Covers the external surface.

  • epidermis - epithelium, keratinised stratified squamous epithelium.
  • dermis - connective tissue; papillary (loose CT) and reticular layer (dense irregular CT)
  • hypodermis - (hypoderm, subcutis) connective tissue,

Adventitia

Within the body.

  • Connective tissue of one structure meets connective tissue of another structure.

Serosa

(serous membrane) has a wet surface (watery).

  • Epithelia and connective tissue lines body cavities. Covers organs in the body.
  • mesothelium - the layer of cells (mesoderm in origin), lining the body cavity of the embryo. In the adult, it is a simple squamous epithelium that covers all true serous membranes (peritoneum, pericardium, pleura).

Mucosa

(mucous membrane) has a wet surface (mucus).

  • Epithelia and connective tissue that lines organs that open to the outside.
