Sensory receptors
- Sense
- Tongue
- Nose
- Eyes
- Sound
Sensory receptors – specialised cells that respond
to a stimulus in the internal or external environment of an organism
and can create action potentials
are energy transducer that convert one form of energy into electrical energy for an electrical impulse
Stimulus – a change in environment
Pacinian corpuscles
Pacinian corpuscle – a pressure sensor that detects changes in pressure on skin
