Sensory organs and structures in animals
Channels for information to be delivered to the brain (“biological transducers”)
What types of stimuli? (what forms of energy?)electricalmechanicalchemicalradiant
Stimuli are transformed into nerve impulsesinterpreted by specialized areas of the brain(Muller, 1830s)
What are receptors?specialized neurons or epithelial cellsoften located in special sensory organs
Exteroreceptors- detect external environment;located on or near body surface
Interoreceptors detect stimuli within the body
Proprioceptors- muscle tension; body position
Energy is converted to membrane potentials
Sensory transduction (e.g., taste)G protein pathway
