What else can I help you with?
What band shortens during skeletal muscle contraction?
during skeletal muscle contraction ,I band and H zone shortens. Sarcomeres
Which attachment usually stays stationary during contraction?
During muscle contraction, the origin of the muscle typically stays stationary. The origin is the fixed attachment point of the muscle, while the insertion, which is the point that moves, is pulled toward the origin. This action allows for the effective movement of bones and joints during contraction.
In addition to myosin what other protein is involved in skeletal muscle contraction?
Myosin acts with Actin during muscle contraction
What happens to the strength of contraction during wave summation?
It increases about to about four times greater than a normal contraction for skeletal muscle.
What other protein is involved in skeletal muscle contraction?
Troponin is another protein involved in skeletal muscle contraction. It works in conjunction with tropomyosin to regulate the interaction between actin and myosin filaments during muscle contraction.
During skeletal muscle contraction myosin cross bridges attach to active sites of?
During skeletal muscle contraction myosin cross bridges attach to active sites of actin filaments. Actin filaments bind ATP. Their growth is regulated by thymosin and profilin.
What is the relatively fixed point of a muscle's attatchment to a bone called?
The relatively fixed point of a muscle's attachment to a bone is called the origin. It is typically located closer to the body's midline and usually remains stationary during muscle contraction.
What is poses my awesome band sets on the actin during skeletal muscle contraction?
Please re-write this so we can understand
What aids lymph flow?
muscular activitybreathing muscle contraction peristalsis
Can skeletal muscle contract without shortening?
Yes. One possibility is that the load on the muscle exceeds the tension produced by the muscle so that the muscle actually lengthens during contraction (eccentric contraction).
What is commonly used to produce ATP during skeletal muscle contraction?
creatine phosphate, anaerobic cellular respiration, aerobic cellular respiration
What happens during skeletal muscle contraction?
During skeletal muscle contraction, motor neurons activate muscle fibers, causing calcium ions to be released from the sarcoplasmic reticulum. The calcium ions bind to troponin, leading to the exposure of active sites on actin filaments. Myosin heads then attach to these active sites, form cross-bridges, and pull the actin filaments towards the center of the sarcomere, resulting in muscle contraction.
