What is basal layer?
A basal layer is the deepest layer of the epidermis.
What is a basal layer?
The basal layer is the deepest layer of the epidermis, the outermost layer of the skin. It contains cells called basal cells that continuously divide and give rise to new skin cells. These new cells then move up through the layers of the epidermis to the surface of the skin.
What is the layer of epidermis that has pigment-producing melanocytes?
The layer of the epidermis that has pigment-producing melanocytes is the stratum basale (basal layer). Melanocytes produce melanin, the pigment responsible for skin color, and transfer it to surrounding keratinocytes.
What layer of the epidermis contains the only cells the are capable of dividing?
The stratum basale (basal layer) of the epidermis contains the only cells capable of dividing through mitosis. These cells are known as basal cells or basal keratinocytes and are responsible for replenishing the outer layers of the epidermis.
Which epidermis is closely adhered to the underlying tissue?
upper epidermis
What is the name of the layer of the epidermis that sits on the basement membrane?
The layer of the epidermis that sits on the basement membrane is called the basal layer or stratum basale. It is the innermost layer of the epidermis where new skin cells are produced.
What is special about the basal layer of the epidermis?
The basal layer of the epidermis is the innermost layer that contains stem cells responsible for the constant renewal of skin cells. These stem cells divide and differentiate into the other layers of the epidermis, ensuring a continuous supply of new skin cells. It plays a crucial role in maintaining the skin barrier and repair mechanisms.
Where is merkel cell located?
Merkel cells are located in the skin's epidermis, particularly in the basal layer. They are found in areas of the skin that are sensitive to touch, such as the fingertips, soles of the feet, and the face.
Identify the epidermal layer in which the following cancers arise a basal cell carcinoma b malignant melanoma c squamous cell carcinoma?
a. Basal cell carcinoma arises in the basal cell layer of the epidermis. b. Malignant melanoma arises from melanocytes located in the basal layer of the epidermis. c. Squamous cell carcinoma arises in the squamous cells of the epidermis, which are found in the upper layers of the epidermis.
What layer of the epidermis is the layer where mitosis occurs?
We find it in the deepest layer of the epidermis called Stratum Basal in which the stem cells undergo Mitosis replacing keratinocytes lost at the stratum corneum, the apical surface of epidermis.
What is stratum basal?
It is apart of the skin and hair shaft
Where are pigment cells located in the body?
Pigment cells (melanocytes) are found in the basal layer of the epidermis.
