Histological Perspective
Both ends of the muscle are pulled together. This is because each muscle fiber is divided into contractile units called sarcomeres. Each sarcomere is composed of layers of thin and thick filaments, Actin and Myosinrespectively. The thick filaments, myosin, are located in the center of the sarcomere, a region called the A-Band. On either side of each A-Band, is a region called the I-Band. The I-Band is primarily composed of the thin filaments (Actin), although the thin filaments do overlap with the thick filaments within a sub region of the A-band called the zone of overlap.
As the muscle contracts the thick filaments pull the thin filaments together on either side, resulting in the apparent contraction of the muscle on both sides.
Gross Anatomical Perspective.
However, because a muscle is anchored at the origin of the stationary bone while its other end attaches at the insertion of the articulating bone and the net force of the contracting muscle pulls the insertion of the muscle to its origin.
It follows that: The correct answer is toward the origin.
What else can I help you with?
What is the end of the muscle that is attached to the movable bone and moves when a skeletal muscle contracts?
Insertion point, which most probably is a tendon.
When a skeletal muscle contracts it usually moves the bone at one end much more than the bone at its other end The attachment of the muscle to the less moveable bone is called its?
origin
When the muscle contracts it pulls on and moves that bone at the joint?
ligament
What do you get when the muscle at the end of the follicle contracts?
uranus
When the muscle contracts what happens to the tendon and bone?
When the muscle contracts, the tendon pulls on the bone to create movement. The tendon is the connective tissue that attaches the muscle to the bone, so when the muscle contracts, it exerts force on the tendon, which in turn moves the bone.
When you flex your arm muscle what happens?
The muscle in your arm contracts. The muscle on the other side of your arm, opposite from the side that you are flexing, stretches.
Which end of muscle moves the most?
The insert
What does a muscle become when it contracts?
A muscle becomes shorter when it contracts.
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.
What happens to the length of a muscle when it contracts?
When a muscle contracts, it shortens in length.
Does the end of the muscle attached to the bone that moves least is the origin of that muscle?
they dont u retard
When a muscle contracts how does its form change?
A muscle that contracts shortens whereas a muscle that relaxes lengthens.
