  1. Proprioception/Neuromuscular Control

  2. Afferent Inputs (3 subsystems) • Vision • Horizontal and vertical references

  3. Afferent Inputs (3 subsystems) • Vision • Vestibular • Head movement • Inner ear • Balance and posture • Somatosensory • Peripheral Afferent Receptors

  4. Somatosensory System • Afferent Receptors • Free Nerve Endings • Hair follicles • Pain receptors

  5. Somatosensory System • Afferent Receptors • Free Nerve Endings • Cutaneous Receptors • Few respond • Respond at extreme ROM

  6. Somatosensory System • Afferent Receptors • Free Nerve Endings • Cutaneous Receptors • Articular (Joint) • QA and SA • Pacinian Corpuscle • Joint capsule • RA • sensitivity
