A unique touch receptor formed from stratum basale cell (and a nerve fiber) is a merkel cell.
The skin, all 6-10 lb. (~3-4 kg) and 20 square feet in an adult, is a giant, washable, stretchable, tough, water-proof sensory apparatus covering your whole body. One of the endings that detect things is a encapsulated nerve ending formed by the tiny nerve cell of a dorsal root ganglion cell in next to a Merkel cell found in the basal layer hairy skin, in hair follicles, and in oral and anal mucosa.This called the Merkel disc and is a sensory receptor for pressure and texture information.
The melanocytes are the melanin-producing cell in the bottom layer of the epidermis of the skin. Merkel cells are receptor cells found in the skin of vertebrates. They aid in the ability to sense light touch.
The layer of the epidermis that is constantly undergoing mitosis is called the stratum basale, also known as the basal layer. This layer is responsible for producing new skin cells that eventually move up through the other layers of the epidermis.
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.
The Stratum Germinativum is the deepest layer of the dermis also known as the Stratum Basale.
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.
Mitosis takes place in the stratum basale of the epidermis, which is the deepest layer where the basal cells are actively dividing to replenish and replace the outer layer of skin cells that are continually shed.
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.
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.
The five layers of the epidermis from outermost to innermost are: Stratum corneum Stratum lucidum Stratum granulosum Stratum spinosum Stratum basale (also known as the stratum germinativum)
From basal layer. This layer is called as stratum basale.
The epidermal layer with a single layer of columnar cells is the stratum basale (basal layer). This layer is located at the bottom of the epidermis and contains basal cells that constantly divide to replenish the upper layers of the skin.
