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 ...
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 .
An oversplit by former Olympic gymnast Irina Tchachina Stretching cat. Flexibility is the anatomical range of movement in a joint or series of joints, and length in muscles that cross the joints to induce a bending movement or motion.
When walking at an average speed of ambulation (~1.25 m/s) the ankle joint requires at least 10-20 degrees of plantar flexion. Limited ankle plantar flexion may result in decreased push off force, which could lead to shorter step length. To compensate for this impairment, increased knee or hip flexion of the swing limb would be needed.
The extension synergy for the lower extremity includes hip extension, adduction and internal rotation, knee extension, ankle plantar flexion and inversion, and toe plantar flexion. [ 1 ] Note that some muscles are not usually involved in these synergy patterns and include the lattisimus dorsi , teres major , serratus anterior , finger extensors ...
Human services is an interdisciplinary field of study with the objective of meeting human needs through an applied knowledge base, focusing on prevention as well as remediation of problems, and maintaining a commitment to improving the overall quality of life of service populations [1] The process involves the study of social technologies (practice methods, models, and theories), service ...
The origin of a muscle is the bone, typically proximal, which has greater mass and is more stable during a contraction than a muscle's insertion. [14] For example, with the latissimus dorsi muscle, the origin site is the torso, and the insertion is the arm. When this muscle contracts, normally the arm moves due to having less mass than the torso.
The iliopsoas is the prime mover of hip flexion, and is the strongest of the hip flexors (others are rectus femoris, sartorius, and tensor fasciae latae). [3] The iliopsoas is important for standing, walking, and running. [2] The iliacus and psoas major perform different actions when postural changes occur.
