What else can I help you with?
During muscle contraction the moves toward the?
During muscle contraction, the Z-lines move closer together as the sarcomeres shorten. This is due to the sliding of actin and myosin filaments past each other, resulting in the contraction of the muscle.
What happens to the Z line during muscle contraction?
During muscle contraction, the Z line moves closer together, causing the muscle to shorten and generate force.
Why is ATP required during a muscle contraction?
ATP is required during a muscle contraction because it provides the energy needed for the muscle fibers to contract and generate force. Without ATP, the muscle would not be able to contract effectively.
The less movable attachment point of a muscle is called the?
The less movable attachment point of a muscle is called the origin. This is typically the point of attachment that remains relatively fixed during muscle contraction, while the other end, known as the insertion, moves towards the origin.
What is the difference between a skeletal muscle's origin and its insertion?
the position at which the end of the muscles is attached by means of a tendon to a movable bone whereas insertion is the attachment of muscles to the movable bone.. also origin is generally closer to the mid line of the body whereas insertion is farther away..
During muscle contraction the moves toward the?
During muscle contraction, the Z-lines move closer together as the sarcomeres shorten. This is due to the sliding of actin and myosin filaments past each other, resulting in the contraction of the muscle.
What happens to the Z line during muscle contraction?
During muscle contraction, the Z line moves closer together, causing the muscle to shorten and generate force.
What happens to a muscle contraction if there is an excess amount of either Ca2 plus or ATP present during the contraction?
During muscle contraction the actin heads pull the sarcomere closed
Where does the muscle attach to the bone?
Where a muscle attaches to a bone is at the origin and insertion points. The origin is the immovable (or slightly moveable) attachment point and the the insertion is the movable attachment point. During contraction the insertion moves towards the origin. HOW a muscle attaches to a bone is through tendons.
What is the site of the muscle attachment that is moved upon contraction?
Insertion
What happens If a muscle is applied to a load that exceeds the muscle's maximum tension?
The muscle length will not change during a contraction.
The more moveable attachment point of a muscle is called the?
The origin is the "immovable" point of attachment of a muscle to a bone.
What is the movable point to which a muscle may be attached?
The "movable" end of a muscle is called the insertion. The "immobile" end is called the origin. Shortening, or contraction, of a muscle causes the origin and insertion to become closer to one another.
What term identifies the site where a muscle attaches to the bone it pulls on?
The term that identifies the site where a muscle attaches to the bone it pulls on is called the "insertion." This is typically the more movable attachment of the muscle, as opposed to the origin which is the less movable attachment site.
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 happens to the muscle tissue when exercising?
muscle contraction
The muscle contracts and shortens and the insertion end moves toward the point of origin. This sentence describes?
Essentially the second half of your question is what happens when a muscle contracts on a larger scale. On a much smaller scale, the contraction of muscle is caused by myosin proteins pulling themselves along the surface of an actin protein, which shortens the muscle. Muscles pull the bone that they are attached to at their point of insertion towards their point of origin.
