Within the gray matter of the spinal cord
The interneurons involved in a withdrawal reflex are located in the spinal cord. These interneurons receive signals from sensory neurons that detect the painful stimulus and transmit signals to motor neurons that cause the withdrawal response. The spinal cord acts as a relay station for these signals, allowing for a quick and automatic response to potential harm.
they are located in the limbs, because the limbs are the effectors of the withdrawal reflex.

Withdrawal reflex or flexor reflex employs sensory neuron, interneuron and motor neuron.
The two types of reflex arcs are the monosynaptic reflex arc and the polysynaptic reflex arc. A monosynaptic reflex arc involves a direct connection between a sensory neuron and a motor neuron, allowing for a quick response, as seen in the knee-jerk reflex. In contrast, a polysynaptic reflex arc includes one or more interneurons between the sensory and motor neurons, enabling more complex responses and integration of information, such as in withdrawal reflexes.
The withdrawal reflex is an example of a polysynaptic reflex involving multiple neurons. This reflex pathway consists of sensory neurons carrying the stimulus information to the spinal cord, interneurons within the spinal cord processing the information, and motor neurons sending signals to muscles to initiate a response, such as withdrawing from a painful stimulus.
The sensory receptors of a withdrawal reflex are located in the skin and muscles of the body. These receptors detect a potentially damaging stimulus and send signals to the spinal cord to trigger a reflexive response, such as pulling your hand away from a hot surface.
The knee-jerk reflex is controlled by the interneurons in the spinal cord.
Flexor Muscles
This is called 'withdrawal reflex' and is possible because of the presence of interneurons in the spinal chord. The "touching of the hot stove" is a classic example in which after contact has been made, the hand is withdrawn before the brain perceives any pain or danger. The interneurons connect afferent to efferent neurons in the spinal chord; thus the signal created by the hot stove does not have to travel to the brain and be interpereted before a reflex can take place.
The withdrawal reflex is a negative feedback reflex that helps the body protect itself from harm. When the body comes into contact with a harmful stimulus, such as touching something hot, the withdrawal reflex causes muscles to contract and move the body part away from the stimulus, which helps to prevent injury.
