The _____ of the scapula is the point where the medial and lateral borders meet. Teres Minor Lateral border of scapula Greater tubercle of humerus Lateral rotation at shoulder Axillary Long Head of Biceps Supraglenoid tubercle of scapula Tuberosity of radius and to ulna by the bicipital aponeurosis Flex elbow supinate forearm and flex shoulder.
Top bumpridge of glenoid fossa.
Supraglenoid tubercle of the scapula. The supraglenoid tubercle scapular tuberosity has a separate center of ossification and is the origin of the biceps brachii muscle. It is subject to avulsion from the tension generated by the biceps brachii muscle particularly in skeletally. Supraglenoid tubercle of scapula a rough surface above the glenoid cavity of the scapula giving attachment to the tendon of the long head of the biceps within the articular cavity of the shoulder joint.
Want to thank TFD for its existence. The supraglenoid tubercle represents a separate center of ossification in foals that unites with the neck of the scapula at approximately 2 years of age. This represents a locus of decreased resistance relative to external forces.
The biceps tendon which transforms to the very strong biceps muscle originates at the supraglenoid tubercle. The supreglenoid tubercle is an area on the scapula where the biceps brachii originates. This area is located above the glenoid cavity and by the base.
See full answer below. Supraglenoid tubercle It is a small rough projection located immediately above the glenoid fossa near the base of the coracoid process. Infraglenoid tubercle It is a rough impression located on the lateral part of the scapula immediately below the glenoid fossa.
This surface of the scapula faces outwards. Longitudinal myotomy of the supraspinatus muscle. A new approach to the supraglenoid tubercle of the scapula.

Find details on Scapula. Fracture - supraglenoid tubercle in horses including diagnosis and symptoms pathogenesis prevention treatment prognosis and more. The extrinsic muscles include the biceps triceps and deltoid muscles and attach to the coracoid process and supraglenoid tubercle of the scapula infraglenoid tubercle of the scapula and spine of the scapula.
These muscles are responsible for several actions of the glenohumeral joint. Watch out a lot more about it. The biceps brachii muscle has two heads one originating from the coracoid process short head and the other from the supraglenoid tubercle of the scapula and superior labrum long head.
The distal biceps tendon attaches to the bicipital tuberosity of the radius. The biceps tendon is a strong supi. Supraglenoid tubercle one on the scapula for attachment of the long head of the biceps muscle.
Fractures of the scapula are uncommon and the majority of these involve the supraglenoid tubercle in young horses 2 years of age or less. Scapula fractures of the neck or body are rare. Preoperative image of a supraglenoid tubercle fracture.
The addition of a figure-of-eight tension band as described for the lag screw fixation complements the plate fixation. Fixation with human distal femur plate. Supraglenoid tubercle of the scapula Insertion.
Medial tuberosity of proximal radius and adjacent ulna Runs through the intertubercular groove of the humerus. From the brachial plexus Origin. Spirals to insert just proximal to biceps.
A discrete radiolucent line separating the supraglenoid tubercle is observed. Both parts are well mineralized and a sclerotic rim is evident adjacent to the radiolucent line separating the tubercle from the scapula. This line continues to the articular surface of the glenoid cavity of the scapula.
A lateral approach to the shoulder joint via a longitudinal myotomy of the supraspinatus muscle was used in the surgical treatment of four cases involving avulsion fractures of the supraglenoid tubercle of the scapula. This approach was developed using cadaver specimens and was compared to previously reported approaches to the supraglenoid tubercle. The _____ of the scapula is the point where the medial and lateral borders meet.

Teres Minor Lateral border of scapula Greater tubercle of humerus Lateral rotation at shoulder Axillary Long Head of Biceps Supraglenoid tubercle of scapula Tuberosity of radius and to ulna by the bicipital aponeurosis Flex elbow supinate forearm and flex shoulder. The answer is b the supraglenoid tubercle of the scapula bone. This tendon runs down through the intertubercular groove of the humerus but does not attach to the humerus bone.
The greater tubercle is not seperated into two parts like in other species A single greater tubercle. Hear articulate with the supraglenoid cavity of scapula to form shoulder. At the distal end thre is a supratrochlear foramen nothing passes though in the cat this is the supracondyloid foramen where the brachial medial Arterie goes though.
