MEDICAL PHYSIOLOGY

Detailed explanation-1: -For the spinal cord though, we can say that there are three types of neurons: sensory, motor, and interneurons.

Detailed explanation-2: -A spinal interneuron, found in the spinal cord, relays signals between (afferent) sensory neurons, and (efferent) motor neurons. Different classes of spinal interneurons are involved in the process of sensory-motor integration. Most interneurons are found in the grey column, a region of grey matter in the spinal cord.

Detailed explanation-3: -At the integrative region, the activity of all receptors or synaptic potentials in the same cell is added and depending on whether the sum is higher than the threshold, the action potential may or may not be generated. Consequently this region is called the trigger zone or the integrative component.

Detailed explanation-4: -The gray matter mainly contains the cell bodies of neurons and glia and is divided into four main columns: dorsal horn, intermediate column, lateral horn and ventral horn column.
