What part of the nervous system is the pathway for messages to get to and from the brain

Think of the brain as a central computer that controls all the body's functions. The rest of the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back.

Explanation:

the oblique cord is a ligament between the ulnar and radius bones in the lower arm near the elbow. it takes the form of a small, flattened band, extending downward and lateralward, from the lateral side of the ulnar tuberosity at the base of the coronoid process to the radius a little below the radial tuberosity.
