Flexor Accessory: Meaning and Functions

Flexor accessory, also known as m. f. The accessorius or pna (from the Latin "accessorius" - additional), is one of the important muscles involved in the movement and functioning of the human body. In this article, we will look at the meaning and function of the flexor accessory muscle and its impact on our daily lives.

The flexor accessory muscle is an additional muscle that is found in the upper body. It has its origins in the upper part of the cervical vertebra and runs along the posterior surface of the neck of the scapula. It then crosses the back of the shoulder joint and joins the outer facet of the humerus. The flexor accessory muscle works in conjunction with other muscles, such as the deltoid and pectoralis major, to provide proper range of motion of the shoulder and upper extremity.

One of the main functions of the flexor accessory muscle is to support the elevation and depression of the shoulder. It plays an important role in lifting and stabilizing the shoulder girdle, which allows us to perform various arm movements. In addition, the flexor accessory muscle helps in externally and internally rotating the shoulder, which is necessary to perform many everyday tasks, such as unpacking and placing objects on a shelf or swinging your arms while walking or running.

In addition to its main functions, the flexor accessory muscle can also be involved in various movements of the neck and head. For example, it can help with forward or sideways head tilt and neck rotation. These flexor accessory functions are especially important when performing tasks that require precision and coordination of head and neck movements, such as driving a car or playing a musical instrument.

Like any other muscle, the flexor accessory muscle can be subject to overexertion and injury. Damage or weakness of this muscle can lead to limited shoulder movement and pain or discomfort in the neck and shoulder area. In such cases, it is recommended to consult a medical specialist for diagnosis and appropriate treatment or rehabilitation.

In conclusion, the flexor accessory muscle is an important muscle supporting movement and function of the shoulder and upper extremity. Its cooperation with other muscles provides us with the ability to perform a variety of tasks in everyday life. Understanding the meaning and functions of the flexor accessory muscle can help us better manage its condition and care for its health. If you are experiencing problems with your shoulder, neck, or head, contact a specialist to receive professional help and recommendations for the treatment and rehabilitation of the flexor accessory and related muscles.
