What muscles cause shoulder horizontal abduction?

What muscles cause shoulder horizontal abduction?

• Posterior Deltoid.
• Middle Trapezius.
• Lower Trapezius.
• Infraspinatus.
• Middle Deltoid.
• Supraspinatus.
• Teres Minor.
• Rhomboid Major.

Which muscles cause horizontal adduction in the shoulder?

Muscles that Horizontally Adduct the Shoulder

• Anterior Deltoid.
• Pectoralis Major.

What is horizontal adduction of shoulder?

This is called horizontal shoulder adduction. It is when your arms move in toward the body along the horizontal or transverse plane. The main muscles involved in horizontal shoulder adduction are the upper fibers of the pectoralis major and the anterior fibers of the deltoids.

What is shoulder horizontal adduction?

Like its antagonistic motion, horizontal abduction, horizontal ADDuction is a motion that occurs in the gravity-eliminated plane if performed in the anatomical position.

What muscles are used in abduction of the shoulder?

The primary muscles involved in the action of arm abduction include the supraspinatus, deltoid, trapezius, and serratus anterior.

What is shoulder adduction and abduction?

Shoulder abduction involves lifting the arms out to the side (as with a lateral dumbbell raise), while shoulder adduction means lowering the arms back to the side (as with a banded lateral pull-down exercise).

Where does horizontal adduction occur?

Horizontal adduction: Moving the upper arm towards the midline of the body when it is elevated to 90 degrees.

What muscles do horizontal adduction?

The pectoralis major muscle helps flexion, internal rotation, and adduction on a horizontal plane.

In what plane of movement do shoulder horizontal adduction and abduction occur?

The clearest examples of frontal plane movements are straight-arm lateral raises and lateral leg raises, which are comprised of adduction and abduction of the shoulder and hip, respectively.

What plane of motion is shoulder abduction?

Abduction and adduction of the shoulder occur in the coronal plane, and about the sagittal axis.

What plane is horizontal abduction in?

Supination: Forearm supination involves turning your forearm upwards, so your hands and wrists are facing up. Horizontal abduction: Like frontal plane abduction, horizontal abduction (occurring on the transverse plane) involves moving a limb towards the midline or center of the body.

What plane is shoulder horizontal adduction?

Horizontal adduction (A) and horizontal abduction are used to describe the position of the arm in the sagittal plane of motion with reference to the center of the torso (horizontal neutral; B).
