The scapula is known as the ″funny bone.″ In terms of form, it is very irregular, and it does not move nearly as much as the other bones in our body. Physiologic joints are formed when the rib cage is moved along by the rib cage as it moves. The scapula articulates with the clavicle and the humerus, resulting in the formation of the shoulder complex.
Which muscles are more effective in rotating the scapula? Trapezius, anterior serratus brevis. Complementing hip joint movement with the muscles responsible for that movement is essential. – Gluteus medius, gluteus minimus, and tensor fascia latae are involved in abduction. The adductors brevis, longus, magnus, gracilis, and pectineus are the adductors used in adduction.
Why is the scapula important to the body?
A significant bone in the body, the scapula is crucial because each one of them serves as a point of attachment for a number of muscles that make up the arm and shoulder. Also articulates with the humerus and clavicle to produce the glenohumeral (shoulder) joint and the acromioclavicular joint, which are located on each side of the clavicle.
How should the scapula move?
- Movement that is beneficial: ″The scapulae should rotate and raise as the arms reach upward,″ adds Price.
- Cueing in the Correct Way: Rubenstein instructs clients to shift their shoulder blades ″back and down,″ like he does with low rows, and avoids instructing them to move the bar.
How much does the scapula move?
The scapula has five degrees of freedom of movement on the thorax: it can move in two’straight-line’ directions and two ‘translations.’ It can also move in one of two ‘translations.’ It has the ability to move in three separate planes and around three different axes.
What moves the scapula forward?
If you engage the whole serratus anterior muscle, it will draw the scapula forward and around the rib cage, which is known as protrusion. By contracting in a distinct manner, its upper and lower fibers assist in producing downward and upward rotation, respectively, of the scapula.
Does the scapula abduct?
Protraction of the scapula is sometimes referred to as abduction of the scapula in some circles. This movement of the scapula along the chest wall is done laterally and anteriorly. It is the serratus anterior that is the primary mover. The pectoralis minor and major, the latter of which acts through the humerus, may be able to help (act as synergists).
What muscles do scapular retraction?
The activities of the trapezius, rhomboids, and latissimus dorsi muscles are responsible for the retraction of the neck. The trapezius, levator scapulae, and rhomboid muscles work together to lift the scapulae off the ground.
What is scapular rhythm?
Terminology. Scapulohumeral rhythm is defined as the coordinated motion of the scapula and humerus experienced during shoulder movement and motion, which has traditionally been viewed as occurring at a ratio of 2:1 (2 degrees of humeral flexion/abduction to 1 degree of scapular upward rotation) during shoulder movement and motion.
How does the scapula move during shoulder flexion?
During shoulder flexion, the scapula should rotate in the following directions: upwardly, posteriorly, and externally at the conclusion of the range of motion. Keep an eye out for excessive adduction or abduction when performing these maneuvers.
Is scapula a bone or muscle?
The scapula, also known as the shoulder blade, is a big triangular-shaped bone that is located in the upper back region of the body. The bone is surrounded and supported by a complex system of muscles that all work together to assist you in moving your arm in different directions.
How do the glenohumeral muscles move?
The shoulder joint, which works in combination with the pectoral girdle, provides for a wide range of motion in the upper limb, including flexion, extension, abduction, adduction, external/lateral rotation, internal/medial rotation, and circumduction, among other movements. In fact, it is the joint with the greatest range of motion in the human body.
How does the scapula attach to the body?
The scapula is a triangle-shaped bone that is flat on one side and triangular on the other (also known as the’shoulder blade’). It is positioned on the dorsal surface of the rib cage in the upper thoracic portion of the rib cage. When the scapula meets the humerus at the glenohumeral joint and the clavicle at the acromioclavicular joint, they come together to create the shoulder joint.
What plane does the scapula move in?
The Scapula is always moving. In the frontal plane, the scapula makes four movements, which are as follows: The act of reaching is connected with elevation when the range of motion of the glenohumeral joint is restricted. Walking with crutches and using a walker are all connected with sadness because they are a closed-chain movement.
What does scapular winging indicate?
It is known as ″winged scapula″ (also known as ″winged shoulder″) when the muscles of the shoulder are either too weak or paralyzed, resulting in a restricted ability to support the shoulder joint. Consequently, the medial or lateral edges of the scapula protrude from the back, giving the appearance of wings.
What bone is the scapula?
In vertebrates, the scapula, often known as the shoulder blade, is one of two major bones that make up the shoulder girdle. When it comes to humans, they are triangular in shape and located on the upper back between the second and eighth rib levels.
What are the 17 muscles of the scapula?

What drives upward rotation of the scapula?
- • Function: stabilizes the scapula against the thoracic wall and assists in the rotation and abduction of the arm.
- • Structure: (90 to 180 degrees) This muscle originates from the surface of the top eight ribs on the side of the chest and inserts along the full anterior length of the medial border of the scapula (shoulder blade).
- – Innervation is provided via the long thoracic nerve (C5, C6, C7)
What causes pain in the scapula?
- Scapular discomfort can be caused by a variety of factors.
- The discomfort in the scapula can also be caused by a bad sleeping posture or by degenerative disorders like arthritis.
- Physical trauma or injury can also cause shoulder blade pain, therefore it is crucial to consult a medical expert for a correct diagnosis and treatment of your shoulder blade discomfort.
- The following are the most common causes of shoulder blade discomfort that occurs in the area between the shoulders:
