Epidermal Layer Of Skin Case Study
Hair shaft have a variety of functions consisting of: protecting sensitive parts of the body from harm (the eye), regulating the body’s temperature (our head), filtering (nose and ears), heat and moisture retention mechanism (genital area and armpits)(Hopkins Medicine, 2016).
Epidermis its function is protecting the body (Hopkins Medicine, 2016).
Papillary layers function consist of: supplying nutrients to selected layers of the epidermis, regulates temperature, and as sensory touch receptors (Cancer, 2016).
Reticular layers function consists of: strengthening the skin, providing structure and elasticity. It also supports varies parts of …show more content…
Cutaneous plexus function is to: supply the fatty tissue of the hypodermis, parts of the dermis, the capillaries for hair follicles, sweat glands, and deep sebaceous glands (Histology, 2016).
Briefly identify and discuss the structural features of skin found in the epidermal layer of skin.
The stratum basale is the bottom layer of keratinocytes in the epidermis. It is responsible for continuously producing renewed epidermal cells. This layer consists of one row of indistinguishable columnar stem cells, which are divided very often. Half of the cells transfer to the next layer to start the maturation procedure. The other half stays in the basal layer and where they are divided over and over again to refill the basal layer (Washington, 2016).
Cells that move into the spinosum layer also known as prickle cell layer transform from a columnar to a polygonal. This is where cells begin to synthesize keratin (Washington, 2016).
The cells in the stratum granulosum also known as granular layer has lost their nuclei and are described as dark clumps of cytoplasmic material. This layer has so much activity as keratin proteins and waterproofing lipids are starting to produce and create a structure in organizing (Washington, …show more content…
The cells are flat and are made up of mostly keratin protein that generates strength to the layer, but also permits the absorption of water. This layer is accountable in providing hydration to the skin an essential function. However, there are complex procedures at work in this layer and a minor disruption can cause a variation of skin problems (Washington, 2016).
Discuss what would happen if a large percentage of the skin was damaged or lost.
There are three degrees of burns. First-degree affects the outer layer known as the epidermis of the skin. Second-degree burns damage the epidermis and the layer beneath known as the dermis. Third-degree burns consist of damaged skin destroyed to its full depth to underlying tissues.
The swelling and blisters from the burns is caused by the loss of fluids from damaged blood vessels. In severe cases loss of fluid can cause a person to go into shock and burns typically lead to infections since the skin the body’s protective barrier is
