Flexor pollicis shortus

The flexor pollicis muscle is a muscle that is located in the wrist and is responsible for flexing the thumb. It is one of the most important muscles in the hand as it allows a person to perform many different activities such as writing, drawing, using tools, etc.

The name of the muscle comes from the Latin word “brevis”, which means “short”. This is due to the fact that the muscle is short and located on the wrist.

Flexion of the thumb with the help of the flexor occurs due to muscle contraction. When the muscle contracts, the thumb bends, and when the muscle relaxes, the thumb returns to its original position.

In humans, the flexor pollicis muscle is located in the area between the wrist and elbow. It consists of several muscle fibers that are located parallel to each other and form a bundle.

This muscle is very important for performing many different activities. For example, it is used when writing, drawing, using tools, and other activities that require flexion of the thumb. In addition, the flexor pollicis muscle is also involved in maintaining the correct position of the hand during work.

However, if the muscle is damaged or does not work properly, it can lead to various problems. For example, a person may have difficulty performing certain activities, such as writing or using tools.

To prevent damage to the muscle, it is recommended to perform stretching and strengthening exercises for the flexor pollicis. It is also important to ensure the correct position of the hand when working and not to overload it.

The flexor pollicis brevis (lat. Musculus pollicis brevis) is a muscle in the hand that is located on the back of the hand. It is responsible for flexing the thumb. This muscle is essential for performing various tasks such as writing, using tools, etc.

The flexor pollicis brevis is one of three muscles that form the “flexor apparatus” of the hand. It works together with other muscles such as the flexor digitorum, extensor digitorum, and extensor carpi to provide proper movement and support to the hand.

Although this muscle is important for everyday life, it can be susceptible to injury and disease. For example, a strain or tear in this muscle can lead to pain and limited movement of the thumb. There are also various diseases associated with this muscle, such as muscular dystrophy and polio.

To prevent injuries and diseases of the short flexor pollicis, it is necessary to properly train this muscle. This can be achieved through exercises aimed at strengthening and stretching this muscle. In addition, proper technique must be observed in performing tasks involving the use of the arm to avoid overuse and injury.

In conclusion, the flexor pollicis brevis plays an important role in a person's daily life. However, he may be susceptible to various diseases and injuries. Therefore, to prevent these problems, it is necessary to train properly and monitor the technique of performing tasks.
