Sensory neurons which trigger reflexes are called nociceptive neurons. After entering the dorsal root of the spinal cord, the nociceptive neuron branches into two terminals: one terminal synapses with an interneuron - a localised neuron which is located entirely within the grey matter of the spinal cord, and this in turn synapses with a motor neuron which then triggers the fast reflex action. The reflex is initiated solely within the spinal cord & doesn't involve the brain at all, but at the same time, the second branch of the nociceptive neuron synapses with a sensory neuron which goes to the brain; the brain then registers the sensation of pain, and can also initiate further motor action if necessary.

What is the neural pathway of a single reflex called?
The neural pathway of a single reflex is called a reflex arc. It involves the sensory neuron carrying information from the receptor to the spinal cord, where it synapses with a motor neuron that carries the response signal to the effector muscle or organ. This simple pathway allows for rapid, involuntary responses to stimuli.
If you accidentally step on a tack with your bare foot the pathway that the nerve impulse takes from your foot to your leg is called?
The pathway that the nerve impulse takes from your foot to your leg is called the sensory pathway. This pathway includes sensory neurons that carry signals from the foot to the spinal cord and then to the brain, where the sensation of pain is perceived and a motor response is initiated to move away from the tack.
What is the name of the short pathway that carries the impulse for an automatic response?
The short pathway that carries the impulse for an automatic response is called a reflex arc. It involves sensory neurons, interneurons in the spinal cord, and motor neurons to quickly produce a reflex action in response to a stimulus, bypassing the brain.
What is a automatic reflex arc?
An automatic reflex arc is a neural pathway that controls reflex actions in response to a stimulus. It involves sensory neurons detecting the stimulus and sending signals to the spinal cord, which then quickly activates motor neurons to produce a rapid and involuntary response, bypassing conscious control from the brain.
What is the location of an interneuron in a spinal reflex pathway?
Interneurons are located in the spinal cord. They act as the middlemen in transmitting signals between sensory neurons (that detect stimuli) and motor neurons (that generate a response). In a spinal reflex pathway, after receiving sensory input from a sensory neuron, the interneuron processes the information before signaling the motor neuron to carry out a response.
The neural pathway of a single reflex is called?
Reflex Arc
What is the pathway between the receptor and the control center in the reflex pathway called?
Afferent pathway

A reflex pathway having only one synapse in the CNS?
Reflexes are rapid involuntary responses to a given stimuli. The reflex pathway that only has one synapse in the CNS is called the monosynaptic reflex arc.
What is the pathway of reflex?

An automatic reflex arc is a neural pathway that controls reflex actions in response to a stimulus. It involves sensory neurons detecting the stimulus and sending signals to the spinal cord, which then quickly activates motor neurons to produce a rapid and involuntary response, bypassing conscious control from the brain.

In a spinal reflex pathway, after receiving sensory input from a sensory neuron, the interneuron processes the information before signaling the motor neuron to carry out a response.
What is the sacral reflex arc?
The sacral reflex arc refers to the neural pathway that controls involuntary responses in the sacral region of the spinal cord. It involves sensory neurons detecting stimuli and transmitting signals to the spinal cord, which then sends motor signals back to the muscles or glands in that region to produce a reflex action. This reflex arc helps regulate functions such as bowel and bladder control.
What nerve acts as the afferent pathway in the pupillary reflex?
The optic nerve (cranial nerve II) carries sensory information about light intensity to the brain as part of the afferent pathway in the pupillary reflex.
