    What are the muscles called?

    Muscles play an important role in the physical activity of a person. They usually make up 42% of body weight. By function, they are distinguished by:

    • short (for example, located between the vertebrae)
    • long (limb muscles)
    • wide (mainly on the chest, abdomen)

    In the human body, you can count about 400 different muscles. What are the muscles called? Consider the muscle groups that perform the most important functions in the human body.

    Back muscles

    Trapezius muscle

    Extensor backIts main function is to make the shoulder blades closer to the spine and lift them up.

    The broadest muscle of the back

    It allows hands to rotate inward, and shoulders - to be brought to the body.

    Extensor back

    This is a muscle that extends back.

    Muscles of the gluteal region

    The gluteal muscles (large, medium and small) play an important role in straightening the bent torso, as well as for making movements in the hip joint of the lower limbs.

    Muscles of the front of the body

    Sternocleidomastoid muscle

    Its main function is to rotate and flex towards the head. The front gear muscle helps to remove the scapula from the spine and its rotation.Muscles of the front of the body

    External oblique abdominal muscle

    With the bilateral work of these muscles, the rib cage descends, and also the body bends forward. With unilateral tension of the external oblique abdominal muscles, the body bends and rotates.

    Rectus abdominis muscle

    The rectus muscle is also needed for flexing the body forward, it helps maintain pressure inside the abdominal cavity.

    Pectoralis major muscle

    • The shoulder-radial muscle is important for flexion in the elbow joint of the arm, as well as in the rotation of the arm inward and outward.
    • Muscles of the pelvic region and lower limbs
    • The iliopsoas muscle flexes the hip and turns it outwards.
    • Pear-shaped muscle is needed to rotate the hips outwards.
    • The tailor muscle flexes both the shin and the thigh.This is one of the longest muscles in our body.
    • The calf muscle is important for extending the foot.
    • The quadriceps muscle of the femur performs a complete extension of the calf in the knee, and also participates in flexion in the hip joint of the femur.
    • Internal locking muscle provides a turn of the hip outwards.
