|
The deltoid tuberosity serves as an attachment site for what muscle?
|
Deltoid
|
|
|
The edge of the glenoid fossa is surrounded by a fibrous ring called the __.
|
Glenoid Labrum
|
|
|
The three ___ are thickenings of the fibrous capsule that surrounds the shoulder joint, and contribute to the formation of the glenoid labrum.
|
Glenohumeral ligaments. (Superior, Middle, Inferior).
|
|
|
Also aiding in strengthening the fibrous capsule of the shoulder is the ___ that passes from the lateral side of the coracoid process of the scapula to the anatomic neck of the humerus.
|
Coracohumeral ligament.
|
|
|
The ____ ligament attaches the coracoid process to the acromion, forming the ____.
|
Coracoacromial ligament. Forms the coracoacromial arch.
|
|
|
The ____ protects the glenohumeral joint from blunt trauma, and prevents superior displacement of the humeral head.
|
Coracoacromial Arch.
|
|
|
The ____ ligaments help maintain the position of the clavicle.
|
Coracoclavicular ligaments.
|
|
|
The ___ ligament provides support for the superior surface of the shoulder.
|
Acromioclavicular ligament.
|
|
|
The ___ is a broad band of connective tissue passing from the greater tubercle to the lesser tubercle of the humerus, forming a bridge over the intertubercular groove for protection of the long head of the biceps tendon.
|
Transverse humeral ligament.
|
|
|
The ___ completely encloses the shoulder joint and is thin and loose to allow for free movement.
|
Articular joint capsule.
|
|
|
There are ___ openings of the articular capsule in the shoulder. What are they for?
|
Two. The first allows for the transition of the biceps brachii. The second establishes a communication between the joint and the subscapularis bursa.
|
|
|
What are the two prominent bursae in the shoulder?
|
1. Subacromial-subdeltoid bursa - the main bursa of the shoulder, and largest in the body. It cushions the rotator cuff muscles and coracoacromial arch.
2. The subscapular bursa. This bursa protects the subscapularis tendon where it passes inferior to the coracoid process and over the neck of the scapula. |
|
|
What bursa is the largest in the body?
|
The subacromial-subdeltoid bursa.
|
|
|
Which bursa cushions the rotator cuff muscles and coracoacromial arch?
|
The subacromial-subdeltoid bursa.
|
|
|
Which bursa protects the subscapularis tendon where it passes inferior to the coracoid process and over the neck of the scapula?
|
The subscapular bursa.
|
|
|
What are the 4 muscle groups that provide stability for the shoulder joint and movement of the upper arm?
|
1. Muscles that connect the upper limb to the vertebral column.
2. Muscles of the scapula. 3. Muscles that connect the upper limb to the anterior thoracic wall. 4. Muscles of the upper arm. |
|
|
What are the 5 muscles connecting the vertebral column to the upper limb?
|
1. Trapezius
2. Levator Scapulae 3. Latissimus Dorsi 4. Rhomboid Major 5. Rhomboid Minor |
|
|
The large ___ muscle covers the posterior aspect of the neck and superior half of the trunk (C7-T12)
|
Trapezius.
|
|
|
The ___ muscle functions to stabilize the scapula as well as elevate, retract, and depress the scapula.
|
Trapezius.
|
|
|
The ___ muscle functions to elevate and rotate the scapula, and lies deep in the neck.
|
Levator scapulae muscle.
|
|
|
The ___ muscle covers the inferior portion of the back as it extends from the spinous processes of the inferior 6 thoracic vertebrae, iliac crest, and inferior three or four ribs to the distal end of the intertubercular groove of the humerus.
|
Latissimus Dors muscle.
|
|
|
The ___ muscle medially rotates, extends, and adducts the humerus.
|
Latissimus Dorsi muscle.
|
|
|
The ___ muscles function to retract the scapula and fix the scapula to the thoracic wall.
|
Rhomboid muscles.
|
|
|
Name the muscles of the scapula (6)
|
1. Deltoid
2. Teres (2): major and minor 3. Supraspinatus 4. Infraspinatus 5. Subscapularis |
