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
What sensory neurons to motor neurons?
Sensory neurons (afferent neurons) send sensory signals from the body to the Central Nervous System. Their cell bodies are always found in a ganglion outside the central nervous system. Motor neurons (efferent neurons) send signals from the central nervous system to the muscles and glands of the body. Their cell bodies are always located in the central nervous system.
What functional differences are there among sensory motor and associative neurons?
Sensory neurons are specialized to translate many forms of input (light waves, sound waves, tissue displacement, molecules suspended in air or dissolved in saliva, and so on) into action potentials. Motor neurons carry commands to glands and muscles. Association neurons have neither specific sensory nor motor functions, but rather form bridges between the sensory and motor neurons.

What are the three types of neurone involved in a reflex action?
The three types of neurons are sensory(afferant) neurons, interneurons, and motor(efferant) neurons. Sensory, or afferent, neurons send information from the receptor to the central nervouse system. Interneurons, found only in the central nervous system, play the role of interpretting the impulse. The motor, or efferent, neurons send the information from the central nervous system to the effector. Receptor->sensory neuron->interneuron->motor neuron->effector.
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 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 are the key factors that influence the generation and propagation of action potential in neurons?
The key factors that influence the generation and propagation of action potential in neurons are the balance of ions inside and outside the cell, the opening and closing of ion channels, and the threshold level of stimulation needed to trigger an action potential.
