Construction Workers Disability Ratio NIOSH The fatal injuries of Biology Diagrams 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 . The forearm is the section of the upper limb from the elbow to the wrist, whose bony structure is formed by the radius (laterally) and ulna (medially). Two muscular compartments - an anterior (flexor) and posterior (extensor) compartment - contain together twenty muscles that act on the elbow and wrist joints, as well as carpometacarpal, metacarpophalangeal, and interphalangeal joints of the Learn the difference between extensor and flexor muscles, their functions, locations, examples, and common injuries. Extensor muscles extend or straighten joints, while flexor muscles flex or bend them.
Key Differences Between Flexor and Extensor Muscles. Understanding the distinctions between these two muscle types is crucial: Function: Flexor muscles facilitate bending, while extensor muscles enable extension.; Contractions: Flexor muscles contract to bring body parts closer, while extensor muscles contract to extend them.; Antagonistic Pairs: Flexor and extensor muscles often work in pairs All the extrinsic muscles of the hand originate in the forearm and then course distally to enter the hand. These can be divided into two groups based on their action: the flexors and extensors. Extrinsic Flexors of the Hand in the Anterior Compartment of the Forearm. Superficial Flexors. Flexor carpi radialis; Palmaris longus; Flexor carpi ulnaris The forearm muscles are divided into two compartments based on location and action: the anterior or flexor compartment and the posterior or extensor compartment. There are a total of 19 muscles in the forearm that help move not only the elbow and wrist joints but also the joints in the hand and fingers.

Learn what flexor and extensor muscles are, how they work, and where they are located in the body. Find out the difference between flexion and extension, and see examples of flexor and extensor muscles in the hand and foot.
Learn about the five muscles of the arm, divided into flexor and extensor compartments. The flexors are biceps brachii, coracobrachialis and brachialis, while the extensor is triceps brachii.
