[The structure of the skin of the ear in domesticated pigs, with special reference to their use for human dermatological research. 1. Macroscopic aspects and hair coat].

To begin with, the study describes macroscopically the typical pigmentation, form and surface sculpture of the external ear of the white domesticated pig. Then the palpable stability and elasticity of the ear integument is analyzed, followed by a detailed and microscopically assisted description of the fine relief of the skin surface, the hair line, the hair density, the angle of hair follicle insertion, and the arrangement of hair follicles on both sides of the auricle. The results obtained are discussed with special regard to the use of the porcine ear integument as a model for human skin.
