Receptors are special sense organs Simple Receptors: Unencapsulated § Free Receptors are simple and include encapsulated and unencapsulated “advise” the brain of one’s movements Receptor Classification by StructuralĪre structurally classified as either simple or complex § Most In skeletal muscles, tendons, joints, ligaments, and connective tissueĬoverings of bones and muscles § Constantly To degree of stretch of the organs they occupy § Found To chemical changes, stretch, and temperature changes Receptor Class by Location: Proprioceptors § Respond In internal viscera and blood vessels § Sensitive To stimuli arising within the body § Found The special sense organs Receptor Class by Location: Interoceptors § Respond To touch, pressure, pain, and temperature § Include To stimuli arising outside the body § Found – respond to light energy (e.g., retina) § Chemoreceptors – respond to chemicals (e.g., smell, taste, changes inīlood chemistry) § Nociceptors – sensitive to pain-causing stimuli Receptor Class by Location: Exteroceptors § Respond – respond to touch, pressure, vibration, stretch, and itch § Thermoreceptors – sensitive to changes in temperature § Photoreceptors

Realization of these stimuli, sensation and perception, occur in the brain Receptor Classification by Stimulus Type § Mechanoreceptors Of sensory receptors results in depolarizations that Specialized to respond to stimuli § Activation Links to and from the external environment PNS in the Nervous System Sensory Receptors § Structures

Sensory receptors, peripheral nerves, associated ganglia, and motor endings § Provides – all neural structures outside the brain and spinal cord § Includes LECTURE OUTLINE CH 13 The Peripheral Nervous System (PNS) Peripheral Nervous System (PNS) § PNS
