Shoulder Muscles Flashcards

1
Q

Glenohumeral Ligaments (GHL)

A

Formed by a group of ligaments that connect the humerus to the glenoid.

These ligaments are the main source of stability for the shoulder

They are the superior middle and inferior glenohumeral ligaments.

They help hold the shoulder in place and keep it from dislocating

Q

Coraco-acromial Ligament (CAL)

A

Links the coracoid to the acromion . This ligament can thicken and cause Impingement Syndrome

Q

Coraco-clavicular Ligaments (CCL)

A

two ligaments (trapezoid and conoid ligaments) attach the clavicle coracoid process of the scapula.

keeping the scapula attached to the clavicle and thus keeping your shoulder ‘square’.

Transverse Humeral Ligament (THL)

A

Holds the tendon of the long head of biceps brachii muscle in the groove between the greater and lesser tubercle on the humerus (intertubercular sulcus).
