Ruffini's corpuscle, also known as a bulbous corpuscle, is a type of sensory receptor found in the skin and joints of mammals. Named after Angelo Ruffini, an Italian histologist who discovered it in the late 1800s, this sensory receptor plays a crucial role in detecting stretching or deformation of the skin.
Structure
Ruffini's corpuscles are made up of elongated capsules of connective tissue with nerve fibers intertwined within them. These nerve endings are sensitive to stretching or pressure, making them particularly important for proprioception, which is the body's ability to sense its position and movements.
Function
The primary function of Ruffini's corpuscles is to detect changes in the skin's mechanical properties, such as skin stretching or movement. They are especially sensitive to sustained pressure or distortion, providing continuous feedback to the brain about the position of body parts in relation to each other.
Location
These sensory receptors are found in the deep layers of the skin, particularly in the dermis and hypodermis, as well as in joint capsules. They are most densely concentrated in areas of the skin that experience the most stretching or movement, such as the fingers, palms, and soles of the feet.
Ruffini's corpuscles are essential for maintaining balance, coordinating movement, and preventing injury by detecting changes in the skin's mechanical properties. Their ability to sense stretching and pressure helps us perform everyday tasks with precision and accuracy.
Ruffini's corpuscle Examples
- Ruffini's corpuscle helps detect changes in skin temperature.
