1 Tire width is the width of the tire measured in mm from sidewall to sidewall. This tire width is 225 mm.  Aspect ratio is the ratio of the height of the tire's cross-section to its width. On our example, 60 means that the height is equal to 60% of the tire's width.
The infrahyoid muscles or strap muscles are a group of four paired muscles in the anterior neck below the hyoid bone. They are responsible for depressing the hyoid during swallowing. Each muscle is supplied by different nerves from the ansa cervicalis.
The nerves that supply the muscles and the skin in the upper extremity leave the spinal cord in a complicated network of nerve fibers, roots and bundlesâthis is called the brachial plexus. These nerves travel down the side of the front of the neck and divide, then rejoin to form the median, radial and ulnar nerves.
