Flexor

Flexors (from the Latin "flexion" - bending) are a group of muscles responsible for bending bones in joints. This is a key element of the human musculoskeletal system, necessary for the proper functioning of all parts of the body.

The flexors are responsible for maintaining the body in an upright position and provide the ability to perform complex motor tasks such as walking, running, jumping, squatting, playing on sports courts and much more. They are also involved in arm movements, such as flexion of the fingers and wrist, and in the movement of the legs, which provide movement of the pelvis and hips.

How do flexors work? The work begins with the activation of the nervous system, which sends signals to the muscles, providing the muscle fibers with the necessary force to bend the joints. When the signal reaches the muscle, a process of contraction and relaxation begins, which leads to the bending of the bone in the desired direction. Muscle tension can be stimulated both by the neuromuscular system and by the mechanical work of the skeleton or other muscle groups.

There are several types of flexors:

1. Abdominolumbar muscle group: These include the abdominal and lower back muscles, such as the rectus abdominis, external and internal obliques. These muscles provide flexion of the spine and allow the torso to maintain a standing posture. 2. Pectoral muscle group: Consists of the muscles of the chest and the anterior wall of the peritoneum, such as the rectus abdominis and serratus anterior. They help the torso compress and lengthen the hips and back. 3. Dorsal flexors: Divided into biceps and triceps muscles, which are located on the back of the back. They are involved in the flexion of the spine and contribute to the flexion of the shoulders and arms
