noun, plural: oval corpuscles
A corpuscle oval in shape found in the papillae of the skin that acts as a mechanoreceptor particularly sensitive to light touch or vibrations (lower than 50 Hertz).
In human skin, these corpuscles were found to wane in number as the person ages (i.e. when touch sensitivity for small probes is lost gradually with age).
These sensory receptors are capable of detecting touch or vibration that is light (lower than 50 Hz) because they are situated in the dermis only superficially.
