Study Notes
Skin Structure
- The skin is the outer covering of the human body
- It consists of three layers: epidermis, dermis, and hypodermis
- The hypodermis stores subcutaneous fat
Skin Conditions
- Abnormal skin conditions can occur due to skin damage or internal body factors
External Causes
- Contusion: a discolored area of skin caused by trauma, resulting from blood escaping from damaged capillaries
- Abrasion: damage to the epidermis, typically non-bleeding scrapes that don't cut into the dermis
Internal Causes
- Acne: a common skin disease caused by oils trapping skin cells in pores, leading to bacterial growth
- Pimples: raised red bumps resulting from acne, considered imperfections of the skin
