Extensor Index Finger Proper

The extensor index finger (musculus extensor indicis) is a muscle that helps us extend the index finger. This muscle is part of the extensor complex of the hand (musculus complexus extensorius manus), which also includes the extensors of other fingers and wrist muscles.

The extensor of the index finger has two heads: palmar and dorsal. The palmar head originates from the medial epicondyle of the humerus, and the dorsal head originates from the lateral epicondyle and interosseous membrane of the forearm.

The functions of the extensor index finger are as follows:

– Extension of the index finger and flexion of the little finger
– Participation in abduction and adduction of the index finger to the palm
– Helps keep the hand in the correct position when writing or working with small objects

The extensors of the index finger can be damaged as a result of injury or disease such as tendinitis or arthritis. In this case, surgery may be required to restore extensor function.

In addition, the index finger extensors can also be used during various exercises and workouts, such as machine curls or push-ups.

The extensors of the index finger are the muscles of our body that provide the ability to extend and abduct the index finger on the hand. However, in some cases, namely, when these muscles are damaged or lost, there may be a need to use a special device - the extensor of the own finger (or more popularly, the pointer).

The article will deal with this device and talk about its types and uses in various areas of life.

The first mention of the pointer can be found in ancient times, when people used various mechanical devices to restore damaged fingers. For example, in China, two-wheeled devices were used for this purpose, which were designed for the rehabilitation of hand and finger joints. In India, a brush served the same purpose and worked like a hand bicycle. Whole sets of devices were also created, for example, used by boxers for training on the floor - they helped boxers restore and improve the motor function of their hands.

Modern devices for the rehabilitation of fingers and wrists began to develop in the early 20th century. With the help of these devices, people could improve their motor function and restore damaged body parts. These devices became widespread throughout the 20th century and are still used in practice today, helping people regain their strength and abilities after injuries and operations on their hands and fingers.
