an isometric contraction iso=same
metric=length
therefore the muscle maintains the same length as it contracts
Insertion point, which most probably is a tendon.
Isotonic contractions involve muscle actions where the muscle length changes as it contracts against a constant load. There are two types: concentric contractions (shortening of the muscle during contraction) and eccentric contractions (lengthening of the muscle during contraction).
A muscle becomes shorter when it contracts.
When a muscle contracts, it shortens in length.
A muscle that contracts shortens whereas a muscle that relaxes lengthens.
insertion
When a skeletal muscle contracts, a protein called a myosin hooks onto and pulls against a "partner" protein calledA. actin.B. a sarcoplasm.C.myofibril.D. a sarcomere.the answer is A actin
The sarcomere is the contractile unit of a muscle fiber.
When a muscle contracts, it pulls with a force generated by the muscle fibers contracting and shortening.
When one muscle in a pair contracts the other expands.
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.
