Flexion and extension are movements that affect the angle between two parts of the body. These terms come from the Latin words with the same meaning. [a] Flexion is a bending movement that decreases the angle between a segment and its proximal segment. [9] For example, bending the elbow, or clenching a hand into a fist, are examples of flexion ...
Flexibility is improved by stretching. [5] Stretching should only be started when muscles are warm and the body temperature is raised. To be effective while stretching, force applied to the body must be held just beyond a feeling of pain and needs to be held for at least ten seconds.
Flexion and extension describe the basic ways your body moves at its joints. Here's what that means for your workouts and training.
In anatomy, flexor is a muscle that contracts to perform flexion (from the Latin verb flectere, to bend), [1] a movement that decreases the angle between the bones converging at a joint. For example, one's elbow joint flexes when one brings their hand closer to the shoulder , thus decreasing the angle between the upper arm and the forearm .
Stretching is a form of physical exercise in which a specific muscle or tendon (or muscle group) is deliberately expanded and flexed in order to improve the muscle's ...
A muscle that fixes or holds a bone so that the agonist can carry out the intended movement is said to have a neutralizing action. A good famous example of this are the hamstrings; the semitendinosus and semimembranosus muscles perform knee flexion and knee internal rotation whereas the biceps femoris carries out knee flexion and knee external ...
This large muscle group would allow the vertebral column to flex forward, but would not permit [citation needed] a large extent of forward flexion. The forward flexion provided by tendinous intersections makes daily activities like stretching or bending over to pick up an object possible. [citation needed]
The gross anatomy of a muscle is the most important indicator of its role in the body. One particularly important aspect of gross anatomy of muscles is pennation or lack thereof. In most muscles, all the fibers are oriented in the same direction, running in a line from the origin to the insertion.
