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 else can I help you with?
When a muscle contracts it?
shortens
What happens to the length of a muscle when it contracts?
When a muscle contracts, it shortens in length.
When a muscle contracts how does its form change?
A muscle that contracts shortens whereas a muscle that relaxes lengthens.
What tissue contracts shortens allowing movement?
muscle tissue
The function of movement in the muscular system?
Muscles are attached to two different bones. When a muscle contracts, it shortens. When it shortens, the shortens the angle between the two bones causing movement.
What is an Isotonic Contractions?
Isotonic contractions. This happens when the muscle shortens as it contracts
Points of muscle attachment are known as the?
Origin and Insertion One of the points of attachment is the ORIGIN (typically the non-moving point of attachment). The other point of attachment is the INSERTION (typically the moving point of attachment). For example - when the brachialis muscle (located on the upper arm) contracts - it shortens the distance between the origin (on the humerus - the upper arm bone and the insertion (on the radius - the forearm bone). The humerus does not move, but the radius does move - it moves closer to the humerus.
What tendons means?
when a muscle contracts or shortens the attached bones are pulled closer to each other
When a muscle contracts?
shortens
What happens when a muscle contracts?
when the muscle shortens (contracts), the two bones come closer together, isometric contraction excepted.
What is muscle attachment and function?
Origin and Insertion One of the points of attachment is the ORIGIN (typically the non-moving point of attachment). The other point of attachment is the INSERTION (typically the moving point of attachment). For example - when the brachialis muscle (located on the upper arm) contracts - it shortens the distance between the origin (on the humerus - the upper arm bone and the insertion (on the radius - the forearm bone). The humerus does not move, but the radius does move - it moves closer to the humerus.
Tissue that can contract and shorten?
The Muscle tissue is the one to contract and shorten when it moves or stretches it pulls on the bone to create movement and it shortens and in some cases it contracts
