This is a condition which causes inflammation and pain along the iliac crest. The Iliac crest is a place where abdominal muscle attaches and regular strenuous activity can lead to temporary muscle weakness and inflammation.
The skin is made up of three main layers: the epidermis, the dermis, and the subcutaneous tissue. Skin health depends on each of these layers both performing their own functions as well as supporting each of the other layers. The epidermis. This is the outermost layer of your skin. There are three sub-layers within the epidermis itself: the outer stratum corneum, the middle squamous cell layer, and the bottom basal cell layer. The stratum corneum is the visible part of the epidermis and is actually a layer of dead skin cells immediately on the skin's surface. This layer uses a protein called keratin to form a tough barrier between the outside world and the more vulnerable cells inside the skin and body. The following types of cells make up the epidermis: Basal cells are at the bottom of the epidermis and continually reproduce to form new keratinocytes. Keratinocytes or squamous cells are in the middle layer of the epidermis and produce keratin, the protein that forms the protective outer layer. Keratin also is used to produce hair and nails.
The epidermis is embryonic ectodermal in origin, and they are separated by the dermis by a basement membrane. The epidermis is composed of many layers of cells forming a stratified epithelium. The cells above the basement membrane are cuboid epithelium and form an actively dividing region known as the Malpighian layer.
