What are sensory receptors?
Sensory receptors are cells or cell parts that detect signals from the environment.
What are signals detected by sensory receptors called?
These signals are called stimuli.
What type of stimuli do some sensory receptors detect?
Some sensory receptors detect mechanical stimuli.
What do receptors involved with our sense of touch detect?
Receptors involved with our sense of touch detect mechanical stimuli.
What type of stimuli do other sensory receptors detect?
Other sensory receptors detect chemical stimuli.
What senses are involved with chemical stimuli?
Chemical stimuli are involved with our senses of taste and smell.
What type of stimuli do other sensory receptors detect?
Others detect electromagnetic stimuli.
What sense is involved with electromagnetic stimuli?
Electromagnetic stimuli are involved with our sense of sight.
