NEET PG DENTAL EXAM

Detailed explanation-1: -Answer and Explanation: Epithelial tissue has no blood supply (avascular) which means it receives nutrients and other important substances from the underlying tissues through diffusion. This tissue is penetrated with nerve endings (innervated) such as in skin, nose, and ears which are important for sensory reception.

Detailed explanation-2: -Epithelial tissues do not contain blood vessels and as such are avascular.

Detailed explanation-3: -Epithelial layers are avascular, but innervated. Epithelial cells have two surfaces that differ in both structure and function. Glands, such as exocrine and endocrine, are composed of epithelial tissue and classified based on how their secretions are released.

Detailed explanation-4: -Epithelial tissue has a nerve supply, but no blood supply and must be nourished by substances diffusing from the blood vessels in the underlying tissue. The basement membrane acts as a selectively permeable membrane that determines which substances will be able to enter the epithelium.
