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 .
Flection or flexion may refer to: The action of bending or the state of being bent; Flexion, the action of bending a joint using a flexor muscle;
In applied mechanics, bending (also known as flexure) characterizes the behavior of a slender structural element subjected to an external load applied perpendicularly to a longitudinal axis of the element.
The newton (symbol: N) is the unit of force in the International System of Units (SI). Expressed in terms of SI base units, it is 1 kg⋅m/s 2, the force that accelerates a mass of one kilogram at one metre per second squared. The unit is named after Isaac Newton in recognition of his work on classical mechanics, specifically his second law of ...
Newton (unit) – the SI unit of force, which uses the symbol N. It is defined as 1 kg⋅m/s 2 , the force which gives a mass of 1 kilogram an acceleration of 1 metre per second per second. It is named after Isaac Newton in recognition of his work on classical mechanics , specifically Newton's second law of motion .
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 ...
