contraction
When the radial muscles of the iris contract, the pupil dilates or becomes larger.
During eupnea, the diaphragm and external intercostal muscles contract to facilitate expiration.
Yes, your respiratory muscles contract each time you exhale to push air out of your lungs. The diaphragm and intercostal muscles are involved in this process.
Muscles shorten when they contract because the muscle fibers within the muscle bundle slide past each other, causing the muscle to contract and pull on the attached bones, resulting in movement.
When muscles contract, they shorten and generate force. This process is controlled by the nervous system, which sends signals to the muscles to release calcium ions. These ions bind to proteins in the muscle cells, causing them to slide past each other and contract. This contraction allows the muscles to produce movement and perform various functions in the body.
Muscles contract and relax to move a joint. ... Muscles contract at a constant rate. Muscles contract and relax to move a joint.
Muscles can contract and shorten
muscles contract and relax by bring about movements.
They contract and relax
If the papillary muscles fail to contract the valves will prolapse. The papillary muscles are located in the ventricles and contract to prevent prolapse.
Muscles require more energy even when they are not very active because they need a baseline level of energy to maintain their structure and function, such as maintaining muscle tone and readiness to contract when needed. This baseline energy consumption is known as the basal metabolic rate of muscles.
No, no muscle is. The cells take turns contracting & relaxing. The "anti gravity" muscles only contract when you're standing up.
Yes, grasshoppers do ventilate. When they contract the muscles in their abdomen, it forces air out through the tracheae. The abdomen goes back to its normal state when the muscles relax.
Yes. Smooth muscle can contract cell by cell. This causes muscles to be contracted for very long periods of time.
Smooth Muscles can, but Cardiac Muscles can not.
