Overview of Sensory Receptors
Agenda • Somatosensory (touch, proprioception) • Vestibular • Auditory • We will cover vision later
Somatosensory Receptors
Diversity • Touch Cutaneous Mechanoreceptors • Pressure • Vibration • Proprioception > mm, tendons & joints Mechanoreceptors • Heat • Cold Nociceptors (Free nerve endings) • Pain
Interneuron Primary Basic Idea (using pain receptor as an example) Primary Perception, Localization, Interpretation Primary Sensory Neuron (PNS) Transmission Second Order Sensory Neuron (CNS) Transduction Reception

Proprioception • Muscle Spindles • Golgi Tendon Organs • Joint Receptors
Proprioception in Muscle Tissue Muscle Spindle: detect change in muscle length Golgi Tendon Organ: detect muscle tension Proprioception in Joint Capsule Joint Receptors: finger ROM
