flexable
If I'm not mistaken I believe that for this movement to happen there are two muscles that need to be used- because muscles work in pairs. For this particular movement I am sure that the Agonist muscle (prime mover), the muscle that relaxes, is the Bicep. And the Antagonist, the muscle that contracts, is the Tricep.
The two concepts that explain how the body produces movement are muscle contraction and joint movement. Muscle contraction occurs when muscles shorten or lengthen in response to nerve signals, causing movement. Joint movement allows for the articulation of bones and the range of motion at joints to create different types of movement.
The precision of movement produced by a muscle is due
A movement that targets one muscle or one section of a muscle.
skeletal and muscle 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.
Isotonic contractions are the type that involve muscle movement. This movement is due to a change in length as the muscle fibers shorten or lengthen.
smooth muscle
No, muscle contraction doesn't always promote movement. For example, in an isometric contraction, the muscle does not change length, so movement is not produced. Additionally, some muscles can contract to stabilize joints without producing visible movement.
The origin and attachment of a muscle play crucial roles in facilitating movement. The origin is the fixed point where a muscle attaches to a bone, while the attachment (or insertion) is the point where the muscle connects to the bone that moves. When a muscle contracts, it pulls on the insertion, causing movement at the joint between the two bones. This coordinated action allows for various movements, such as flexion, extension, and rotation, depending on the muscle's alignment and function.
