Non-nucleated cells are seen in______?
Ans. c. Stratum corneumStratum corneum also known as horny layer consists of cells without nucleus and hence does not divide.This layer functions as a mechanical barrier and prevents entry of microbes from environment into the body as well as prevents leakage of fluids from body to environment. This is called as Barrier function.In palmoplantar skin there is an additional electron- lucent zone, the stratum lucidum, between the granulosum and corneum. These cells are still nucleated, and may be referred to as 'transitional' cells.In certain conditions (like psoriasis) there is retention of nucleus in stratum corneum known as parakeratosis.
