GENERAL HISTOLOGY

Detailed explanation-1: -The withdrawal reflex is polysynaptic, meaning that, in addition to the sensory and motor neurons, this response utilizes interneurons which pass signals between the sensory and motor neurons, ultimately creating multiple synaptic connections.

Detailed explanation-2: -The withdrawal reflex in the leg can be examined and measured, using an electromyogram to monitor the muscle activity in the upper leg (biceps femoris) while applying increasing electrical stimulation to the lower leg (sural nerve) on the same side of the body.

Detailed explanation-3: -Reflexes: involuntary movements A reflex arc includes a sensory neuron that sends a signal straight to the spinal cord (bypassing the brain) which in turn generates a response such as a quick muscle contraction so fast that it’s subconscious.
