When would a patient have a third degree burn?
A third-degree burn is referred to as a full thickness burn. This type of burn destroys the outer layer of skin (epidermis) and the entire layer beneath (the dermis).
Which skin pigment is made in the skin as a natural defense against UV radiation?
Melanocytes are derived from neural crest cells and primarily produce melanin, which is responsible for the pigment of the skin. They are found between cells of stratum basale and produce melanin. UVB light stimulates melanin secretion which is protective against UV radiation, acting as a built-in sunscreen.
What color skin is associated with pigment producing cells?
The basal cell layer contains cells called melanocytes. Melanocytes produce the skin coloring or pigment known as melanin, which gives skin its tan or brown color and helps protect the deeper layers of the skin from the harmful effects of the sun.
How do you treat a small third-degree burn?
Treatment for small burns
- Wash the area daily with mild soap.
- Apply an antibiotic ointment or dressing to keep the wound moist.
- Cover with gauze or a Band-Aid to keep the area sealed.
- Apply antibiotic ointment frequently to burns in areas that cannot be kept moist.
How does skin protect against thermal damage?
The skin’s immense blood supply helps regulate temperature: dilated vessels allow for heat loss, while constricted vessels retain heat. The skin regulates body temperature with its blood supply. The skin assists in homeostasis. Humidity affects thermoregulation by limiting sweat evaporation and thus heat loss.
Which skin pigment is made in the skin as a natural defense against UV radiation quizlet?
Which skin pigment is made in the skin as a natural defense against UV radiation? Melanin is the only one of the three pigments (melanin, carotene, and hemoglobin) that contribute to skin color that is actually produced in the skin itself.
What is the function of melanin?
In its various forms, melanin fulfills a variety of biological functions, including skin and hair pigmentation and photoprotection of the skin and eye. Pigmentation of the skin results from the accumulation of melanin-containing melanosomes in the basal layer of the epidermis.
Which changes in the color of skin are often an indication?
20) Changes in the color of skin are often an indication of a homeostatic imbalance. Which of the following changes would suggest that a patient is suffering from Addison’s disease? A) The skin takes on a bronze or metallic appearance. B) Black-and-blue marks become evident for no apparent cause.
What is the treatment for pale skin with low blood pressure?
A Caucasian patient with pale skin is treated for low blood pressure with medication that elevates the blood pressure; however, the skin’s pallor does not change. What is the most likely cause of the pallor in this patient?
Which type of skin cancer is most likely to metastasize?
The skin cancer most likely to metastasize is cancer of the melanocytes. A patient has skin that is slightly blue in color. A likely treatment for this person might be ________.
Where is the dense fibrous connective tissue portion of skin located?
