What is Flexor Pollicis Longus?
Flexor pollicis longus is a long muscle placed in the forearm. Most often it is used to bend and control of the thumb and is found only in humans - no other primates have muscles. Its secondary action is to help bend the wrist when the thumb is in a bent state. The name comes from Latin and literally means "long bending of the thumb". There are a number of injuries that can suffer the muscle, including tendinitis.
The origin of Flexor Pollicis Longus is on the radius. From there it extends down the arms and eventually becomes a flat tendon. It passes through the carpal tunnel and inserts on a part of the thumb. Muscle innervation is a nerve known as an anterior interosseous and blood is made of front interosseous artery. Although muscle is present in almost all people, there are certain variations in its presentation. For example, the muscle can join the tendon increment in some cases. There may also be slides associated with other muscles such as pronator teres.
The muscle action is to bend thumbs on two different joints. These are known as the primary and weak joints of the muscle. The primary is the interphalangal joint and here is the strongest muscle. It also helps to bend the thumb on the metacarpophalngeal joint, albeit without the same force as the primary joint.
The most common daily use of Flexor Pollicis Longus is to grasp the object of hands such as a glass or can. However, any movement that includes thumb bending will include the use of muscle. For this reason, Flexor Pollicis Longus injuries can be extremely frustrating and to adversely change the quality of life of a person until they heal.
Flexor Pollicis Longus, using a wrist bending section, is important to increase muscle flexibility and reduce the chance of injury. To perform the wrist bend section, the stretcher should become in front of the wall with the arm directly at the front and palm up. The stretcher should slowly bend the wrist down so that the palm is directed to the wall. This should cause a section in the wrist flexor muscles. SameAs with all sections, this should be held for about 30 seconds before it repeats several times.
