Study Notes
Skin Structure and Function
- Sebaceous glands are primarily responsible for most skin problems.
- The epidermis continuously sheds and replaces the stratum corneum layer.
- Langerhans cells located in the stratum spinosum play a vital role in protecting against infections.
- Collagen and elastin fibers provide skin with strength and flexibility.
- Sweat pores are formed by the openings of sudoriferous glands.
Immune Response and Skin Composition
- Antigens are foreign substances that trigger an immune response in the body.
- The stratum corneum is made up of keratin protein cells, contributing to skin protection.
- Sebaceous glands are sac-like and linked to hair follicles.
- The stratum lucidum layer is exclusive to the palms of the hands and soles of the feet.
Skin Protection and Composition
- The acid mantle maintains a slight acidity on the skin's surface to prevent bacterial invasion.
- Essential components of skin cells include keratin, a protein crucial for skin health.
- Thickest skin areas are found on the palms of hands and soles of feet.
- The hormone androgen influences the production of sebum in the skin.
pH and Skin Health
- The pH of the skin is essentially the pH of the acid mantle.
- The combination of sebum and perspiration forms the skin's acid mantle, protecting it.
- Epidermal ridges contribute to the formation of fingerprints.
- There are no sebaceous glands on the palms of hands and soles of feet.
Skin Layers and Connective Tissue
- Connective tissue is primarily located in the dermis layer of the skin.
- Pores serve as tiny openings for sweat or sebum to exit the skin.
- The subcutaneous layer acts as a protective cushion for bones and gives shape to the body.
- The subcutaneous layer is not considered part of the epidermis unlike the stratum corneum, stratum lucidum, and stratum basale.
Aging and Skin Characteristics
- The aging process results in the deterioration of collagen and elastin, leading to the formation of wrinkles.
- Skin consists of three main layers: the epidermis, dermis, and subcutaneous layer.
- Mitosis, or cell division, occurs in the stratum basale.
- Eccrine glands are responsible for regulating body temperature, excreting waste, and maintaining skin’s acidic pH.
- The upper layer of the dermis, known as the papillary layer, is rich in blood vessels and capillaries.
Gland Functions and Sweat Production
- Sudoriferous glands are responsible for sweat production, featuring a coiled base with a duct leading to the surface of the skin.
