Approximately how many Pacinian corpuscles are found in every square centimeter of skin?

Pacinian corpuscles, also known as lamellar corpuscles, are specialized sensory receptors located deep in the dermis and in subcutaneous tissues. They are responsible for detecting deep pressure and vibration. The density of these receptors can vary based on the specific area of the body.

On average, there are approximately 14 Pacinian corpuscles per square centimeter of skin. This number reflects the typical concentration found across various regions, although it can be higher in areas such as the fingertips or lower in other skin regions. Understanding this average is important in the context of the integumentary system, as it showcases how sensory input from the skin can vary depending on location, ultimately contributing to our perception of touch and pressure.
