Glenohumeral Rhythm
This is referred to as "scapulohumeral rhythm."
Scapulohumeral Rhythm.
Phase 1:
Humerus 30° abduction
Scapula minimal movement
Clavicle 0° - 15° elevation
Phase 2:
Humerus 40° abduction
Scapula 20° rotation
Clavicle 30° - 36° elevation
Phase 3:
Humerus 60° abduction 90° external rotation
Scapula 30° rotation
Clavicle 30° - 50° posterior rotation Up to 30° elevation
All of these phases have important input by the Rotator Cuff muscles.
What else can I help you with?
What bursa does not belong to the glenohumeral joint?
The subscapular bursa does not belong to the glenohumeral joint. It is located between the subscapularis tendon and the neck of the scapula, within the shoulder joint but not directly associated with the glenohumeral joint.
What ligaments that support the glenohumeral joint?
The 4 supporting ligaments of the glenohumeral joint are: -coracohumeral ligament (between the coracoid process and humerus) -3 glenohumeral ligaments (between the glenoid process and the humerus)
What is the plane of motion for the glenohumeral joint?
The glenohumeral joint moves in multiple planes of motion, including flexion/extension, abduction/adduction, and internal/external rotation. This allows for a wide range of movement in the shoulder joint.
What connects the arm to the body?
The glenohumeral joint which is also known as the "shoulder joint"
What joint does the scapula and the upper arm bone meet?
The scapula and the upper arm bone meet at the glenohumeral joint, also known as the shoulder joint. This joint allows for a wide range of motion, including flexion, extension, abduction, adduction, internal rotation, and external rotation of the arm.
What is the prefix of glenohumeral?

The subscapular bursa does not belong to the glenohumeral joint. It is located between the subscapularis tendon and the neck of the scapula, within the shoulder joint but not directly associated with the glenohumeral joint.

Which head of the triceps brachia will be stretched if the glenohumeral joint is flexed?
The only long head of the triceps is related to the moment of glenohumeral joint. This glenohumeral joint is more commonly called as shoulder joint. Whether this long head of the triceps is stretched or not, can not be commented.
What is the suffix of glenohumeral?
-al meaning pertaining to
An example of the ball and socket?
The glenohumeral joint (the shoulder joint)
What is scapulohumeral rhythm?
Scapulohumeral rhythm:(describes the timing of movement at these joints during shoulder elevation.)first 30 degrees of shoulder elevation involves a "setting phase": The movement is largely glenohumeral.Scapulothoracic movement is small and inconsistent.after the first 30 degrees of shoulder elevation: The glenohumeral and scapulothoracic joints move simultaneously.Overall 2:1 ratio of glenohumeral to scapulothoracic movement.You can observe scapulohumeral rhythm by palpating the scapula's position as a person elevates the shoulder. Helpful scapular landmarks for palpation are the base of the spine and the inferior angle.Scapulohumeral rhythm serves at least two purposes.It preserves the length-tension relationships of the glenohumeral muscles; the muscles do not shorten as much as they would without the scapula's upward rotation, and so can sustain their force production through a larger portion of the range of motion.It prevents impingement between the humerus and the acromion. Because of the difference in size between the glenoid fossa and the humeral head, subacromial impingement can occur unless relative movement between the humerus and scapula is limited. Simultaneous movement of the humerus and scapula during shoulder elevation limits relative (arthrokinematic) movement between the two bones.
Horizontal abduction of the glenohumeral joint. What muscles are involved?
Coracobrachialis Muscle
What is considered to be an extrinsic glenohumeral muscle?
latissimus dorsi & pectoralis major
What two joints does the biceps brachii cross?
glenohumeral and trochleoginglymoid joints
The correct name for the shoulder joint?
There are two joints in the shoulder - the 'main one' that joints the bone of the arm (humerus) to the shoulder blade (scapula) is called the glenohumeral joint. A smaller joint connects the shoulder blade with the collar bone (clavicle). This is called the acromioclavicular joint.
What is the plane of motion for the glenohumeral joint?
The glenohumeral joint moves in multiple planes of motion, including flexion/extension, abduction/adduction, and internal/external rotation. This allows for a wide range of movement in the shoulder joint.
