Gas expands, volume increases (surface area increases) as P = F/A. Clearly force also needs to increase to keep P constant. A greater force means a greater rate of change of momentum, so the molecules must have a greater mean kinetic energy. Therefore the gas must be at a higher temperature meaning heat energy (Q) must be supplied.
When the shoulder is shrugged, this muscle is at work. When a heavy bag is carried, the levator scapulae muscle helps the body bear the burden. This muscle begins at the vertebrae just below the skull, called the cervical vertebrae. It is attached to the transverse processes of the cervical vertebrae.
LEVATOR SCAPULA IN THE LEFT AIC, RIGHT BC PATTERNED PATIENT. By: Michael Cantrell, MPT, PRC. The levator scapula muscle is categorized in a group of muscles called the axio-scapular. group along with rhomboid major and minor, serratus anterior and trapezius. The. attachment sites for levator scapula are the dorsal tubercles of the transverse processes of.
