Answer:
Causes contraction of the muscles
Explanation:
Ballistic stretching utilizes the energy of a moving body or an appendage trying to constrain it past its typical scope of movement. This is extending, or "heating up", by skipping into (or out of) an extended position, utilizing the extended muscles as a spring which hauls you out of the extended position.
This stretching is not usually recommended as the chances of injury in this stretching are at higher risk.
Answer:
It is normal for there to be veins visible underneath the tongue, partly because the mucous membrane is so thin and translucent in this region, but where these vessels become dilated and tortuous, they may appear round and black like caviar.
Compared to adults, the infants rib cage at the bottom is not as RIGID.
Answer:
Muscle contraction is the activation of tension-generating sites within muscle fibers. In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length, such as by holding a heavy book or a dumbbell at the same position. The termination of muscle contraction is followed by muscle relaxation, which is a return of the muscle fibers to their low tension-generating state.
