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 hyoid bone is a U-shaped bone that is held in place by the strap muscles of the anterior triangle of the neck. The bone has a central body (forming the center of the âUâ) with two smaller protruding structures on the superior surface (lesser horns) and two larger bony protrusions from the body (greater horns).
