Sensory Perception

sensory receptors stop sending signals when they are repeatedly stimulated

• sensation

• projection

• sensory adaptation

dendrites embedded in tissue as receivers, respond to pain and temperature

• Free Nerve Endings

• Encapsulated

• Specialized

embedded in connective tissue to increase sensitivity (pressure and touch)

• Free Nerve Endings

• Encapsulated

• Specialized

senses chemicals, mostly found in nose/mouth

• chemoreceptor

• thermoreceptor

• mechanoreceptor

• nocireceptor

senses temperature changes

• chemoreceptor

• thermoreceptor

senses changes in pressure, vibration and body position

occurs in heart, lungs and intestines

• chronic pain

feels as though it is coming from a different part
