Forearm muscles (the main cause of forearm muscle pain)

The upper arm is the part of the forearm from the shoulder to the elbow. The part of the upper arm muscles between the elbow and the wrist are triceps brachii brachii muscle biceps brachii muscle deltoid muscle coracobrachii muscle. There are connective tissue, nerve tissue, muscle tissue, and the skin in the anterior area of the forearm is thin and has greater mobility. There are important veins and their branches in the middle and ulnar side of the superficial fascia, and there are cephalic veins and their branches in the radial side of the medial forearm cutaneous nerve, as well as the median nerve and ulnar nerve of the lateral forearm cutaneous nerve; From the radial to the ulnar, the forearm muscles are divided into two main communities: the front group superficial lt-brachioradialis muscle flexor carpi radialis muscle flexor palmaris longus muscle and the flexor carpi ulnaris muscle. They are like the bass part of the band, responsible for wrist flexion, like the wrist flexion during shooting. Imagine the moment when a basketball takes off lightly at the fingertips, the front group deep lt-flexor digitorum flexor digitorum probitum, these muscles are like fine.

There are many methods to exercise the muscles of the forearm. Wrist bending is one of the effective methods. It mainly exercises the flexor flexor muscles of the forearm, including the palmar and medial sides of the forearm. By bending the elbow, bending the wrist and turning the forearm internally, you can exercise these muscles of the forearm. The movements of wrist bending require accuracy. The movements of wrist bending are the movements involving the most muscles and concentrated stimulation, and therefore it is also the easiest movements to exercise. Reverse wrist bending; The forearm muscles are an important part of the human upper limb. They are responsible for the movement between the wrists and fingers. Specifically, the forearm muscles are composed of many muscles, including the extensor thumb muscle, the abductor thumb muscle, the flexor digitorum superficialis muscle and the flexor carpi ulnaris muscle. Through synergy, our hands can perform various complex movements, such as grabbing objects, mastering tools, and writing. The development of the forearm muscles directly affects the flexibility of the hand.

To exercise the forearm muscles, you can use the following methods to bend the body. Hold the dumbbell with both hands or one hand. Hold the dumbbell to the side of the body. Hold the bell and bend it up to the front of the shoulder. Then slowly lower it to restore the main exercise area. The forearm extensor muscles and the upper arm front muscles are holding the wrist bending action points. Hold the barbell with both hands, palm down, the grip distance is the same as the shoulder width. The upper arm is close to the body and bend the barbell upward to the limit. Then slowly lower it; The skeleton structure of the forearm In the human forearm, there are two bones parallel to the long axis of the forearm. They are the radius and the ulna. The two bones are the main attachment points of the forearm muscles. The muscles of the forearm are mainly divided into the anterior group and the posterior group. The vast majority of these muscles originate from the medial epicondyle or lateral epicondyle of the humerus. These positions are located above the elbow joint. The termination point of the distal muscles belonging to the humerus may be located on the bone surface of the radius and ulna, or may extend to the wrist.

If you want to exercise your forearm muscles,forearm musclesYou can try these methods. Bend your body and hold the dumbbell with your arms close to the side of your body. Then slowly bend the dumbbell to your shoulders, and then slowly lower this action will allow your forearm extensor muscles and upper arm front muscles to be exercised. Hold the wrist, bend your hands, hold the barbell with your arms also close to the side of your body, then bend the barbell vigorously, and then slowly lower this action mainly exercises the forearm extensor muscles and the outer side of the upper arm; The forearm muscles are mainly divided into two groups: front and rear, and each group is divided into two layers: deep and deep. The specific classification and function are as follows: The anterior group muscles: the brachioradialis muscle, which allows the forearm to flex at the elbow joint, and can also pronate or supinate the forearm, and adjust the extreme pronation or expronation of the forearm to the median position. The flexor carpi radialis muscle flexes the elbow and flexes the wrist and tightens the metacarpal aponeurosis. Prevent the blood vessels and nerves on the palm side from being compressed when grasping the instrument for a long time and forcing the flexor carpi ulnar muscle to flex the wrist and the flexor digitorum superficialis muscle to flex the elbow.

1 Barbell bending action: Hold the barbell with both hands and place it on the chest, with the center of the fist forward. The distance between the two hands is the same as the shoulder width or slightly wider. Keep the upper body in a posture with your chest chest, your abdomen and your waist tight. Looking forward and inhaling, hold the bell vertically Push up until the arms are completely straightened, pause for 23 seconds, then exhale, slowly put down to restore the exercise effect. This action is mainly aimed at exercising the flexor muscles of the forearm, which can effectively enhance the strength and endurance of the forearm muscles. 2 Reverse.

How to practice the forearm muscles

The forearm muscles are an important part of the human upper limb. They are responsible for the movement between the wrist and the fingers. The following is a detailed explanation of the forearm muscles. The forearm muscles are composed of many muscles, including the extensor thumb muscle, the abductor thumb flexor digitorum superficialis, and the flexor carpi ulnaris muscle. These muscles are distributed in different positions and levels of the forearm and work together to complete various hand movement functions. The cooperation and coordination of the forearm muscles enables the hand to complete various complex movements.

The forearm muscles are located around the radius and ulnar, and are mainly divided into flexor muscles and extensor muscles. The specific classification is as follows: The first layer of the forearm flexor muscles includes the pronator teres brachioralis muscle, the flexor carpi radialis muscle, the palmaris longus muscle, and the second layer of the flexor carpi ularis muscle has only one muscle, that is, the third layer of the flexor digitorum superficialis muscle, the third layer of the flexor digitorum superficialis muscle, and the fourth layer of the pronator muscles of the forearm extensor muscles mainly includes the extensor carpi radialis longus radialis extensor digitorum brevis extensor digitorum.

1. The flexor muscles of a forearm are divided into four layers in front. The first layer is the brachioradialis muscle pronator teres muscle, the flexor carpi radialis muscle, the palmaris longus muscle, and the flexor carpi ulnaris muscle. The second layer has only one muscle, that is, the flexor thumb longus muscle. The third layer is the flexor digitorum profundus muscle. The fourth layer is the pronator muscle. The posterior group of the forearm muscles, that is, the extensor muscles, is divided into two layers. The superficial layer is mainly the radial side of the extensor carpi longus.

2. The forearm muscles mainly include the following muscles: 1 The brachioradialis muscle is located on the lateral side of the forearm. It is a long fusiform muscle. Its main function is to make the forearm perform pronation movements and help the elbow flex in daily life and work. For example, movements such as using tools to lift weights require the participation of the brachioradialis muscle. 2 The pronator teres and supinator teres and supinator muscles are responsible for pronation and supination of the forearm respectively. The pronator teres are located on the superficial layer of the forearm.

3. The forearm muscle groups are mainly divided into the main muscle group on the front side of the forearm and the main muscle group on the back side of the forearm. The main muscle group on the front side of the forearm starts from the lateral epicondyle of the humerus and ends at the base of the styloid process of the radius. The main function is to flex the forearm and cause the forearm to rotate internally or externally, maintaining the median position of the forearm. The main function of the pronator teres starts at the medial epicondyle of the humerus, and the main function of the lateral side of the radius is to flex the forearm and cause the forearm to rotate internally.

4. Pain in the forearm muscles may occurforearm musclesMuscle strain, scapulohumeral periarthritis, rheumatoid arthritis and other reasons, and further improvement of relevant examinations and treatment is needed. 1 Muscle strain, excessive activity of forearm muscles and pain in muscle tissue engaged in heavy physical work may also cause stiffness and inconvenience to exercise. In severe cases, it may affect normal work and life. 2 Shoulder shoulder shoulder muscle pain may occur.forearm musclesPeriarthritis of shoulder.
