The type of neuron that detects bright light and provides high-resolution color vision is called a cone cell. Cone cells are photoreceptors found in the retina of the eye, and they are responsible for color discrimination and sharp visual acuity in well-lit conditions. There are three types of cone cells, each sensitive to different wavelengths of light, corresponding to blue, green, and red colors. This allows for the perception of a wide spectrum of colors and detailed images in bright environments.
The receptor is the part of the neuron (usually a dendrite) that detects a stimulus. Dendrites are extensions of the main cellular body of the neuron called the soma; the impulse is passed on to another neuron at the other end, which is called the axon. Neurons transmit impulses to each other via electro-chemical connections to each other that are known as synapses.
The pathway that an impulse travels from your foot back to your leg is an example of a reflex arc. A reflex arc includes a sensory receptor (in this case, a receptor in your toe), sensory neuron, motor neuron, and effector (leg muscle). Some reflex arcs include interneurons. In other reflex arcs, a sensory neuron communicates directly with a motor neuron.
Reflexes involve a sensory neuron that detects a stimulus, an interneuron in the spinal cord that processes the information, and a motor neuron that sends the response signal to the muscle or gland. These three neurons work together in a reflex arc to produce a rapid and involuntary response to a stimulus.
The cell body, or soma, of the neuron contains the cell nucleus which is responsible for regulating the cell's activities. It also integrates incoming signals and decides whether or not to generate an action potential, the electrical signal that travels down the neuron.
Interneurons(also called relay neuron, association neuron, connector neuron or local circuit neuron) are multipolar neurons that connects sensory neurons to motor neurons.

an action potential moves along the neuron
The first element in a spinal reflex is the sensory receptor, which detects a stimulus. The last element is the effector, which carries out a response to the stimulus.
This is what happens:a receptor detects a stimulus (change in the environment)a sensory neuron sends a signal to the relay neuronthe relay neuron sends the signal to the motor neuronthe motor neuron sends a signal to the affected partthe affected part produces a response
A specialized area of sensory neuron that detects a specific stimulus is called a sensory receptor. These receptors are designed to respond to specific forms of stimulation, such as touch, light, or sound, and convert the energy from these stimuli into electrical signals that the nervous system can interpret.
Neuron
The reflex arc includes the sensory neuron (sensory intake) to the motor neuron (motor response). This two neuron arc is the fastest. Many times an interneuron at the level of the spinal cord is involved. It passes information to the brain more slowly. It is like an "incident report".
A reflex arc is a neural pathway that controls a reflex action. It involves a sensory neuron that detects a stimulus, sends a signal to the spinal cord or brain, where it is processed, and then a motor neuron sends a signal back to muscles or glands to produce a response. This process allows for rapid, automatic responses to stimuli without conscious thought.
The receptor is the part of the neuron (usually a dendrite) that detects a stimulus. Dendrites are extensions of the main cellular body of the neuron called the soma; the impulse is passed on to another neuron at the other end, which is called the axon. Neurons transmit impulses to each other via electro-chemical connections to each other that are known as synapses.
Summarized below are the 5 major components of the reflex arc: 1. Receptor 2. Afferent (sensory) neurons 3. Association neuron 4. Efferent (motor) neurons 5. Effector
When a sensory receptor detects a stimulus, an impulse is transmitted via a sensory neuron to the spinal cord. In the spinal cord, the impulse is processed and a response is generated, which is then sent via a motor neuron to the effector (muscle or gland) to carry out the reflex reaction. This entire pathway occurs rapidly and automatically without involvement of the brain.
The Inter-neuron (also known as the local circuit neuron, relay neuron or the association neuron) is the neuron which connects the afferent and the efferent neurons in the neural pathways.
