Objective
I can describe how sensory receptors transmit information to the nervous system.
Part 1 of 3
Key concepts
3 concepts
- 1
Sensory receptors convert stimuli into electrical signals through a process called sensory transduction.
- 2
A stronger stimulus leads to a higher frequency of action potentials, and some receptors adapt to sustained stimulation.
- 3
Sensory neurons transmit action potentials to the central nervous system, where the information is processed and integrated.
