NEET PG DENTAL EXAM

Detailed explanation-1: -The basal cell s continually divide, and new cells constantly push older ones up toward the surface of the skin, where they are eventually shed. The basal cell layer is also known as the stratum germinativum due to the fact that it is constantly germinating (producing) new cells.

Detailed explanation-2: -The two primary functions of the stratum basale are 1) proliferation and 2) attachment of the epidermis to the dermis. Cells of the stratum basale essentially represent germinal cells (“brick generators”) responsible for the generation of all cells of the epidermis.

Detailed explanation-3: -The stratum corneum is the outer layer of the skin (epidermis). It serves as the primary barrier between the body and the environment. The epidermis is made up of five layers: stratum basale: the deepest layer of epidermis, made up of cuboidal and columnar cells.

Detailed explanation-4: -The stratum basale is a single row of columnar or cuboidal cells resting on the basement membrane zone that separates the epidermis from the dermis (see Fig. 1-5). Most of these cells are keratinocytes that are constantly reproducing and pushing upward to replenish the epidermal cells above.
