Encapsulated nerve endings are specialized sensory receptors designed to detect specific types of stimuli. In this case, they are primarily responsible for sensing vibration. These structures often have a protective capsule which enhances their sensitivity to mechanical distortions. When vibratory stimuli occur, they cause deformation of the encapsulated nerve endings, leading to the activation of the sensory neurons. This process allows the detection of vibrations, which can vary in frequency and amplitude.

In contrast, itch is generally detected by unencapsulated nerve endings, while pain is sensed through free nerve endings that respond to harmful stimuli. Temperature sensations also arise from different types of receptors, primarily thermoreceptors, which are not encapsulated. Thus, encapsulated nerve endings have a unique role in the sensory system connected specifically to the perception of vibrations.
