The scraped skin of an abrasion can contain particles of dirt. Thin-skinned bony areas (like knees, ankles and elbows) are more prone to abrasions than thicker, more padded areas. First aid for abrasionsĪn abrasion means that the surface layers of the skin (epidermis) has been broken. The two broad categories of skin wounds include abrasions and incised wounds.
Sebaceous glands, hair follicles, nerves and blood vessels are found in the dermis. The dermis lies underneath and consists of elastic fibres (elastin), for suppleness, and protein fibres (collagen) for strength. The epidermis refers to the surface layer and is made of several sheets of skin cells. It consists of two main layers – the epidermis and the dermis. It varies in texture and thickness from one part of the body to the next. It is soft to allow movement, but tough enough to resist breaking or tearing. Skin is the largest organ of the human body.
