Structurally, the skin consists of the epidermis and the dermis.It is the largest, heaviest organ in the horseâs body. Its healthy condition is of vital importance to health and survival. The epidermis is made up of several stratified layers of tough, non-vascular cells that vary in thickness.ar 8 9 THE SKIN The skin is a highly organised, complex system of nerves, tissue and cells designed to harmonise the horseâs metabolism with his internal and external environment.

The epidermis is the outer layer of skin, which is composed of several layers of cells. It provides a barrier of protection from foreign substances. The epidermis is thickest in large animals like horses.It includes multiple types of cells, including keratinocytes, melanocytes, Langerhans cells, and Merkel cells.Each of these cells has special functions. Keratinocytes provide a protective layer that is constantly being renewed in a process called keratinization.In this process, new skin cells are created near the base of the epidermis and migrate upwards.ach of these cells has special functions.
