diaphragm....
smooth muscle
It produces protein.
The general opposite of contraction is expansion, or possibly inflation. For muscles, the opposite of contraction is relaxation.
contraction and relaxation of the heart muscles
contraction and relaxation of the heart muscles
A hereditary disease of the muscles characterized by prolonged contraction of the muscles whenever voluntary motion is attempted, contraction and relaxation being slow and the muscles stiff.
Cats breathe faster when they purr because the act of purring requires the contraction and relaxation of muscles in their diaphragm, which can lead to an increase in their breathing rate.
Contraction and relaxation are two opposites. They work together when the muscles of the body work. A good example is the contraction and relaxation of the heart. The contraction allows blood to be distributed to the parts of the body while the relaxation allows the heart to be oxygenized and therefore fill up blood to be distributed to the whole body.
The active part of breathing involves the contraction of the diaphragm and intercostal muscles to expand the chest cavity, allowing air to enter the lungs. The passive part of breathing involves the relaxation of these muscles, causing the chest cavity to decrease in size and air to be expelled from the lungs.
Myotoniamyotonia
Both aid in the expansion and relaxation of lungs.
Shivering is the rapid contraction and relaxation of muscles to generate heat.
