Integumentary System Worksheet Describe the different types of skin cancers, including the type of cells they arise from and the appearance of thelesions.
Types of Skin Cancer
Melanoma
This type of skin cancer begins in melanocytes, which are pigment cells. Melanoma can occur on any skin surfaces and is usually on the neck, the head or between shoulders in men. In women, melanoma is often on the skin on lower legs and on the hips. Melanoma is rare in dark skin people and it normally develops under toenails and fingernails. Patients with Melanoma have brown or black skin lesion that are irregular in symmetry and coloration
Basal Cell Skin Cancer
This type of skin cancer begins in the basal cell layer of skin. Basal cell skin cancer usually occurs in skin areas that have been in the sun. This is the most common skin cancer among people with fair skin. Patients with Basal cell Cancer have pink and waxy bumps that can bleed after a minor injury.
Squamous Cell Skin Cancer
This type of cancer originates in squamous cells. It is often in areas not in the sun such as feet and legs. However, for fair skin people, it appears in areas that have been in the sun. This is the most common type of skin cancer among dark skin people. Patients with this skin cancer have dull red, rough, and scaly skin lesions.
Actinic Keratosis
This type of skin cancer begins in squamous cells. Patients with this type of cancer have rough, pink, or red scaly patches on areas of the skin exposed to the sun.
Kaposi’s Sarcoma
This is a rare type of skin cancer. It begins in endothelial cells. It features brownish-red to blue skin lesions that occur mostly on feet and legs.
2. What is the most common risk factor for skin cancer and how can we protect ourselves from skin cancer?
Risk Factors for Skin Cancer
The most common risk factor for skin cancer is exposure to sunlight, which is a source of UV radiation. The sun’s rays cause skin damages, which can lead to skin cancer. Individuals can protect themselves from skin cancer by avoiding outdoor activities when the sun’s rays are strong usually during the middle of the day. The rays can go through windows, clouds, windshields, and light clothing. We should also wear long pants, long sleeves, and particularly tightly woven fabrics. People should also wear sunglasses that absorb UV radiation to protect the skin area around the eyes. It is also advisable to wear wide brim hats that shade the neck and face.
3. How is the blister on Frank’s foot similar to a burn? Distinguish between first second and third degree burns.
The blister on Frank’s toe is similar to the blister that develops in a second-degree burn in terms of the splotchy appearance.
First Degree Burns
This is the least serious of the three types of burns. In a first-degree burn, the outer layer of the skin burns. The skin is usually swollen and red in color although the outer layer of skin is not burned through. There is often a swelling and there might be some pain.
Second Degree Burns
A skin injury is a second-degree burn if the first layer of the skin is burned through and the second layer is burned. Blisters develop and the appearance of the skin changes to a reddened, splotchy appearance. There is severe pain and swelling in the second degree burns.
Third Degree Burns
This is the most severe skin burn and it involves all layers of the skin. Third degree burn may affect muscle, fat and even bones. The burned areas may appear dry and white or may be charred black. Difficulties in exhaling or inhaling and carbon monoxide poisoning may occur if a third degree burn victim inhales smoke.
4. What are the two major risk factors associated with burns?
The two main risk factors of burns are exposed heating sources and unsafe storage of inflammable materials.

Integumentary System

...?Neural Communication The way in which neurons communicate is fundamental to understanding the physiology of the psychological functioning. Communication is based off of an electrochemical signal. This is created by the movement of ions between the outside and inside of the membranes which produce the electrical charge that carries the electrical signals throughout the body. This is accomplished by the sodium potassium pump. The membranes are semi permeable which allows ions to polarize and depolarize the neuron. This is what creates the electrical charge necessary for communication between neurons. Once an electrical signal is passed through a neuron, a refractory period will occur. This occurs after the neuron has reached action...

Case Study - The Integumentary System

...?The Integumentary System The integumentary system is the largest organ of the body. Its primary function is to protect underlying tissues and organsfrom bacteria or from any sustainable external damage posed by the surrounding environment. It is divided into three major parts, namely: 1) the epidermis, 2) the dermis and 3) the subdermies or subcutaneous layer (Nakate, 2011). The epidermis is the outer most skin layer that contains no blood vessels, and is sustained only by the capillaries found in the dermis. The cell layers - Melanocytes, keratinocytes, Merkel and Langerhan are located in this layer that protects the outer skin from breaking easily thus preventing the entry of pathogens (Musslimani, 2010). Next comes the dermis... ) are...
