Ruffini Endings is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.

Overview

Mechanoreceptors are sensory receptors that respond to mechanical stimuli such as pressure, stretch, vibration, and touch. They are essential for proprioception, tactile perception, and hearing. [@djouhri1999]

Ruffini endings (also called Ruffini corpuscles or spindle endings) are encapsulated mechanoreceptors found in the skin, subcutaneous tissue, and joint capsules. They detect skin stretch, finger position, and joint angle. [@iggo1960]

Structure

Location

  • Skin: Deep dermis and subcutaneous tissue
  • Joints: Joint capsules ( Ruffini endings)
  • Fingers: Particularly abundant in fingertips

Anatomy

  • Capsule: Elongated, cylindrical connective tissue sheath
  • Axon terminal: Enters capsule, branches extensively
  • Support cells: Surround terminal branches
  • Size: 1-2 mm length, 50-100 μm diameter
  • Orientation: Typically parallel to skin stretch lines
