Explain Skin Anatomy and Physiology in Short

A wound interrupts the continuity between the epithelium and the skin. Understanding skin anatomy and physiology will help podiatrists and chronic wounds care specialists better understand different aspects of skin healing. The skin is the body’s largest organ. Skin problems can significantly impact patients’ self-esteem and psychological well-being because they are easily visible. To learn about methods for addressing skin problems in clinical settings, students can enroll in nursing assistant programs in Illinois (training program).

The Skin Anatomy and Physiology

The skin of the human body is composed of three layers: epidermis (outer layer of skin), dermis (inner layer), and subcutaneous connective tissue. The basement membrane separates the dermis from the epidermis. The thickness of the skin depends on where it is located and is determined primarily by the thickness of the epidermis or dermis.

Epidermis

The epidermis, or outermost layer, is avascular. The epidermis is made up of keratinocytes and dendritic cells. The epidermis skin cells are dominated by keratinocytes, which account for more than 90% of the cells. They are essential in skin function as a barrier and restore integrity during acute wound healing by epithelization. On the contrary, the dendritic cell plays a vital role in the immune system.

Stratum Corneum is composed of flattened, anucleated cells called “keratinocytes.” The stratum corneum consists of “keratinocytes,” flattened and anucleated. The cells are filled with an insoluble, fibrous, and tough protein called keratin.

Stratum Lucidum: Below the stratum corneum is a second layer of upper skin called “stratum lucidum.” It is not present on other epidermis layers but only in thicker skin areas such as the palms and soles. It is not present in areas with thinner skin, such as eyelids.

Stratum Granulosum: This layer is also called the “granular layers” due to granules within the keratinocytes. The keratinocytes are not flattened yet, and they have a diamond-shaped shape.

Stratum Spinosum: This layer is named for the spine-like projections on keratinocytes. These spines are not found in living cells but can be seen as an artifact during tissue preparation.

Stratum Basale: The innermost or base layer of the epidermis is called the stratum basale. This layer contains mitotically active human cells that produce new keratinocytes, which push up to the upper epidermis layers.

Dermis

The thickest and most vascular part of the human skin is the dermis. The dermis contains more fibroblasts than the epidermis, which comprises keratinocytes. It also contains the vasculature as well as the innervation for the skin. The thickness of the dermis can vary depending on where the body is located, which results in different thicknesses of skin in body systems.

The Skin’s Functions

The skin is the body’s most prominent organ. Understanding and appreciating these major functions will help clinicians to treat skin diseases better.

Protection: The skin’s primary function is to protect internal major organs from external pathogens and environmental agents. It acts as a barrier for the body.

Thermoregulation: Skin is a major player in the body’s temperature regulation. Sweating and blood vessels & circulation are the two main mechanisms that regulate body temperature.

Sensation: There are several receptors on the skin that detect sensations such as pain, temperature, blood pressure, and touch. These sensations then travel by cranial nerve fibers up to the cerebral cortex, where they are translated.
