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 motor branch directed to the deep muscles of the neck and the muscles beneath it the hyoid bone, as well as innervate the sternocleidomastoid and trapezius muscles. Mixed branch of cervical plexus is the phrenic nerve (n. phrenicus). Motor fibers are sent to the phrenic nerve to the diaphragm, and sensitive innervate the pleura and pericardium. Brachial plexus (plexus brachialis) formed branches of the lower four cervical nerves and the anterior branch of the 1st thoracic nerve.
