This is not considered as a true joint
Sternoclavicular joint
Subacromial joint
Glenohumeral joint -
Acromioclavicular joint -
Subacromial joint
The spine of the scapula is the landmark used to locate what spinal level?
T3
This is the only truth regarding the intertubercular groove:
It is also known as radial
The medial boundary is the Teres minor
The roof is the transversus ligamentus
The floor is the latissimus dorsi
The floor is the latissimus dorsi
Which of the following cannot produce abduction?
Supraspinatus
Latissimus dorsi
Middle deltoids
Trapezius
Latissimus dorsi
The axillary nerve passes through what intermuscular space?
Quadrangular space
At what branch of the brachial plexus does the radial nerve emerge?
Posterior
What is the orientation of the acromion
Orientation is posterior, lateral, and superior
This statement does not describe the subacromial joint:
It is also known as the subhumeral joint
It is the supraspinatus outlet
It is within the acromiohumeral interval
Its bursa decreases the friction between the acromion and the infraspinatus
Its bursa decreases the friction between the acromion and the infraspinatus
This is not a part of the glenohumeral ligament:
Superior glenohumeral ligament
Middle glenohumeral ligament
Inferior glenohumeral ligament
Posterior glenohumeral ligament
Posterior glenohumeral ligament
The ligament keeps the tendon of the long head of the biceps in place within the bicipital groove?
Transverse humeral ligament
This muscle does not extend the shoulder:
Posterior deltoid
Latissimus dorsi
Subscapularis
Teres major
Subscapularis
What action is not produced by the serratus anterior muscle?
Protraction of the scapula
Rotates the scapula upwards
Raises the ribs during inspiration
Flex the shoulder
Raises the ribs during inspiration
This part of the pectoralis major can horizontally adduct the shoulder:
Clavicular part
This nerve comes from the nerve roots of C5, C6, and C7.
Long Thoracic nerve
This is the strongest and stiffest among the ulnar collateral ligament
Anterior band
The oblique posterior band and the posterior band of the UCL supports the elbow against valgus force at this degree:
Beyond 90
This head of the triceps originates in the posterior surface of the humerus (inferior to the radial groove)
Medial head
The radial nerve does not innervate this muscle:
Triceps
Anconeus
Brachialis
Pronator Teres
Brachialis
Which among these muscles has a different innervation:
Brachialis
Coracobrachialis
Biceps brachii
Brachioradialis
Brachioradialis
This statement is not true regarding the triceps being able to extend the shoulder:
The elbow should be extended so that the proximal fibers can flex the shoulder
The distal fibers should be in its active insufficiency so that the proximal fibers can be recruited to extend the shoulder
It can be done whether the forearm is supinated or pronated
NOTA
The elbow should be extended so that the proximal fibers can flex the shoulder
Carrying angle of male and female in degrees
Males 11-14 deg
Females 13 - 16 deg
This statement is incorrect regarding the biceps brachii:
A simultaneous flexion of the shoulder and elbow and supination of the forearm will result from an isolated unopposed contraction of the biceps
When the forearm is supinated, it acts in flexion of the elbow with or without a load, in slow or in fast movements in either concentric or eccentric contraction
Its effectiveness as a supinator is almost four times as effective as the supinator at an angle of 90 degrees
It is most effective as a supinator when the elbow is flexed at about a 145 degree angle
It is most effective as a supinator when the elbow is flexed at about a 145 degree angle
Its nerve divides include C5, C6, C7, C8, and T1
Radial Nerve
It is the largest nerve of the upper limb
Radial nerve
A little farther down the arm, it passes obliquely toward lateral to run behind the humerus in its spiral groove, deep to the triceps
Radial Nerve
This ligament, accompanied by the supraspinatus muscle, prevents the downward dislocation of the humeral head:
Coracohumeral ligament
This muscle has an extensive origin from the whole lower half of the shaft of the humerus and inserted by a tendon into the tuberosity of the ulna below the coronoid process, its sole concern is flexion of the elbow joint.
Brachialis
These muscles retract the protracted scapula and turn the glenoid fossa downwards, thus forcibly lowering the raised arm. With other muscles, they keep the scapula applied to the chest wall.
Trapezius
This nerve supplies the Serratus Anterior muscle and arises from the C5, C6, C7 roots of the brachial plexus
Long thoracic nerve
This elbow flexor is innervated by the radial nerve and attaches proximally to a ridge on the humerus above the lateral epicondyle
Supinator
