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.
In the recovery phase, cervical muscle strengthening and conditioning should be continued. Strength-training programs are used to fully recover the strength that the athlete had prior to the injury. Training should be focused on muscles supporting the injured brachial plexus nerve, such as the shoulders and the surrounding cervical spine region. The neck also should be protected (eg, use of cervical neck rolls, cervical pillows) until strength is regained.
