Jul 31, 2023 · The skin contains several glands, hair, nails and nerve endings that allow it to function optimally. This article will discuss the embryology, gross anatomical and histological features of the appendages of the skin. Additionally, pathologies that affect the appendages and their consequences will also be discussed.
Skin appendages (or adnexa of skin) are anatomical skin-associated structures that serve a particular function including sensation, contractility, lubrication and heat loss in animals. In humans, some of the more common skin appendages are hairs (sensation, heat loss, filter for breathing, protection), arrector pilli (smooth muscles that pull ...
Skin appendages develop from the epidermis and dermis during embryonic development. Skin appendages play important roles in various functions, including protection, sensation, thermoregulation, and excretion. The distribution and characteristics of skin appendages vary across different regions of the body.
Jul 23, 2023 · Conclusion: The histology of skin appendages reveals their unique structures and functions in maintaining skin health and overall well-being. Understanding the histology of hair follicles, sebaceous glands, sweat glands, and nails provides insights into their roles in thermoregulation, protection, sensory perception, and aesthetics ...
Aug 21, 2023 · Skin appendages are derived from the skin and include hair, nails, and glands. The main functions of the skin are protection (barrier against ultraviolet radiation, microorganisms, and water loss), the synthesis of. vitamin D. , detection of sensation (e.g., touch, temperature, pain), and the regulation of body temperature.

The skin appendages are housed in the dermis, usually in the mid- to deep dermis. These appendages are within the hair follicle, which is shaped like a well and is lined by epithelium. Therefore, in a first-degree or second-degree burn, it is from these appendages that the epithelium begins to regenerate and heal the burn.
