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.

Which neurons decide about the action for a certain stimulus?
Sensory neuron
What process describes the conversion of an external stimulus to an internal action potential?
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.
What transmission of the depolarization wave along the neurons membrane?
Action potential
When a stimulus is applied to a sensory ending what kind of potential is produced?
When a stimulus is applied to a sensory ending, it can lead to the generation of a receptor potential. This receptor potential is a graded potential that can trigger an action potential along the sensory neuron, leading to the transmission of the sensory input to the central nervous system for processing and interpretation.
What sensory neurons to motor neurons?
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.

What are the three types of neurone involved in a reflex action?
The three types of neurons involved in a reflex action are sensory neurons, interneurons, and motor neurons. Sensory neurons carry signals from sensory receptors to the central nervous system. Interneurons process the sensory information within the central nervous system. Motor neurons transmit signals from the central nervous system to muscles or glands to produce a response.
What are relay neurons?
An interneuron (also called relay neuron, association neuron, connector neuron or local circuit neuron) is a neuron that forms a connection between other neurons. Interneurons are neither motor nor sensory.
How do sensory neurons and motor neurons act in opposite ways?
Sensory neurons transmit signals from sensory receptors towards the central nervous system to detect external stimuli, while motor neurons transmit signals from the central nervous system to muscles and glands to initiate a response or action. In this way, sensory neurons bring information in and motor neurons send information out to carry out a response.
What is usually the sites of the initial action potential in neurons?
Axon hillocks

When a stimulus is applied to a sensory ending, it can lead to the generation of a receptor potential. This receptor potential is a graded potential that can trigger an action potential along the sensory neuron, leading to the transmission of the sensory input to the central nervous system for processing and interpretation.
What sensory neurons to motor neurons?
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.
What functional differences are there among sensory motor and associative neurons?
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.
How are neural impulses generated?
Neural impulses are generated when a neuron receives signals from other neurons or sensory receptors, causing a change in its membrane potential. This change in membrane potential triggers an action potential, a rapid electrical signal that travels down the axon of the neuron. This action potential then triggers the release of neurotransmitters at the synapse, allowing the signal to be passed on to other neurons.
