Frequent question: What stratum of the epidermis is responsible for basal cell carcinoma?

What layer of epidermis is basal cell carcinoma?

About 8 out of 10 skin cancers are basal cell carcinomas (also called basal cell cancers). These cancers start in the basal cell layer, which is the lower part of the epidermis. These cancers usually develop on sun-exposed areas, especially the face, head, and neck. They tend to grow slowly.

Does basal cell carcinoma start in stratum basale?

Basal cell carcinomas start in the stratum basale and usually spread along this boundary. At some point, they begin to grow toward the surface and become an uneven patch, bump, growth, or scar on the skin surface (Figure 1). Like most cancers, basal cell carcinomas respond best to treatment when caught early.

What part of the integumentary system is affect by basal cell carcinoma?

Basal cell carcinoma is a form of cancer that affects the mitotically active stem cells in the stratum basale of the epidermis.

Where is basal cell carcinoma most commonly found on the body?

Basal cell carcinoma often appears as a slightly transparent bump on the skin, though it can take other forms. Basal cell carcinoma occurs most often on areas of the skin that are exposed to the sun, such as your head and neck.

Which is the epidermis?

The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands.

What is the function of Germinative layer of epidermis?

The stratum germinativum is a Latin term, which translates to germinative layer. This layer is composed of germinative (or basal) keratinocytes. These cells are actively dividing to provide new cells to replenish lost skin from normal shedding.

Is stratum Basale the basement membrane?

Stratum basale, also known as stratum germinativum, is the deepest layer, separated from the dermis by the basement membrane (basal lamina) and attached to the basement membrane by hemidesmosomes.

What is the function of the epidermis in the integumentary system?

The epidermis, the outermost layer of skin, provides a waterproof barrier and contributes to skin tone. The dermis, found beneath the epidermis, contains connective tissue, hair follicles, blood vessels, lymphatic vessels, and sweat glands.

Is the epidermis avascular?

The epidermis is the outermost part, made of stratified squamous epithelial tissue. So, are there blood vessels in the epidermis? Nope. It’s epithelium and epithelial tissue is avascular.
