Sensory Systems Chp. 12

SENSORY RECEPTORS Input side of PNS Function: collect & transmit information from environment to CNS Information sent to CNS as Action Potential

5 Functions of Sensory System Reception - Transduction - Amplify - Transmit - Integrate -

Types of Sensory Receptors Mechanoreceptors (tactile) - A. Pacinian corpuscles - B. Meissner corpuscles - Proprioreceptors - Thermoreceptors - A. Ruffini's corpuscles - B. Krause's end bulbs -

Types of Sensory Receptors cont. 4. Chemoreception - a. Gustatory receptors - b. Olfaction - 5. Auditory -

Types of Sensory Receptors cont. Gravity - Vision - a. Cones - b. Rods -
