  2. Glenohumeral ligaments - Wikipedia

    en.wikipedia.org/wiki/Glenohumeral_ligaments

    The most important ligament involved in shoulder joint stability is the Inferior Glenohumeral Ligament. During abduction of the arm, the middle and inferior ligaments become taut while the superior ligament relaxes. The radius of curvature of the head of the humerus is greater superiorly than inferiorly, which further stretches these ligaments ...

  3. Shoulder joint - Wikipedia

    en.wikipedia.org/wiki/Shoulder_joint

    The rotator cuff muscles of the shoulder produce a high tensile force, and help to pull the head of the humerus into the glenoid cavity. The glenoid cavity is shallow and contains the glenoid labrum which deepens it and aids stability. With 120 degrees of unassisted flexion, the shoulder joint is the most mobile joint in the body.

    The body has to be rotated about 30 to 45 degrees towards the shoulder to be imaged, and the standing or sitting patient lets the arm hang. This method reveals the joint gap and the vertical alignment towards the socket. [26] Transaxillary projection. The arm should be abducted 80 to 100 degrees. This method reveals: [26]

    Holding one end in both hands, palms facing the floor, pull straight back with your elbows at a 90-degree angle. From that position, raise your forearms to create another 90-degree angle. Then ...

    Those in the lateral compartment only have weak participation in plantar flexion though. The range of motion for plantar flexion is usually indicated in the literature as 30° to 40°, but sometimes also 50°. The nerves are primarily from the sacral spinal cord roots S1 and S2. Compression of S1 roots may result in weakness in plantarflexion ...

  7. List of flexors of the human body - Wikipedia

    en.wikipedia.org/wiki/List_of_flexors_of_the...

    In anatomy, flexor is a muscle that contracts to perform flexion (from the Latin verb flectere, to bend), [1] a movement that decreases the angle between the bones converging at a joint. For example, one's elbow joint flexes when one brings their hand closer to the shoulder , thus decreasing the angle between the upper arm and the forearm .

  8. Anatomical terms of motion - Wikipedia

    en.wikipedia.org/wiki/Anatomical_terms_of_motion

    Flexion and extension are movements that affect the angle between two parts of the body. These terms come from the Latin words with the same meaning. [a] Flexion is a bending movement that decreases the angle between a segment and its proximal segment. [9] For example, bending the elbow, or clenching a hand into a fist, are examples of flexion ...

  9. Glenoid fossa - Wikipedia

    en.wikipedia.org/wiki/Glenoid_fossa

    By being so shallow the glenoid cavity allows the shoulder joint to have the greatest mobility of all joints in the body, allowing 120 degrees of unassisted flexion. Additional range of motion in shoulder flexion (typically up to 180 degrees in humans) is also accomplished by the great mobility of the scapula (shoulder blade) through a process ...
