Summary Introduction
Introduction:
The spinal cord is a collection of nerve tissues that arise from the brain stem. It is a site which contains many motor neurons, interneurons and complex neural circuits. It is often known as ‘nuts and bolts’ of the nervous system. It controls and enables the forces on muscles and its adaptive movements.
