if the graded potential of threshold size reaches a trigger zone

Disturbances to sensory neurons can cause depolarization of the neuron's membrane, reaching a threshold that triggers an action potential. This action potential then travels along the neuron's axon to the central nervous system, where it is processed and interpreted as a sensory experience.
Sensory neuron
The process is known as sensory transduction. It involves converting an external stimulus, such as light or sound, into an electrical signal (action potential) in sensory neurons. This electrical signal is then transmitted to the brain for further processing and interpretation.
Action potential
Sensory neurons transmit information from sensory organs to the central nervous system, while motor neurons transmit information from the central nervous system to muscles or glands to produce a response. This process allows for motor responses to be generated in response to sensory input, enabling movement and action in the body.
Sensory neurons transmit information from sensory receptors to the central nervous system (CNS), while motor neurons send signals from the CNS to muscles to produce movement. Associative neurons, also known as interneurons, facilitate communication between sensory and motor neurons within the CNS. They help integrate and process incoming signals before generating a motor response.
