Pacinian corpuscles are found in which layer of the skin?

• A. In the deep dermis
• B. In the basal epidermis
• C. In the epidermis
• D. In the stratum corneum

Answer: (A)

Pacinian corpuscles are large mechanoreceptors that respond to deep pressure and high-frequency vibration. They reside in the deep dermis (often extending into the subcutaneous tissue), where the dense connective tissue supports their onion-like lamellated structure. This location places them away from the epidermal layers—basal epidermis, the epidermis as a whole, and the stratum corneum—which do not contain Pacinian corpuscles.
