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.
SCALENE MUSCLES. The scalenes are a series of muscles that work like scaffolding, connecting the cervical vertebrae to the thoracic cage. The scalenes originate on the transverse processes of the cervical vertebrae (C02âC07) and attach to the first and second ribs of the thoracic cage.kay, basically they let me stuff my face, but the neck muscles do much more than that! The neck muscles (and neck anatomy on the whole) are responsible for head movement, stabilizing the upper region of the body, assisting in swallowing, helping to elevate the rib cage during inhalation, and more.
