At what branch of the brachial plexus does the radial nerve emerge?

Answer 6

Posterior

Question 7

What is the orientation of the acromion

Answer 7

Orientation is posterior, lateral, and superior

Question 8

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

Answer 8

Its bursa decreases the friction between the acromion and the infraspinatus

Question 9

This is not a part of the glenohumeral ligament:
Superior glenohumeral ligament
Middle glenohumeral ligament
Inferior glenohumeral ligament
Posterior glenohumeral ligament

Answer 9

Posterior glenohumeral ligament

Question 10

The ligament keeps the tendon of the long head of the biceps in place within the bicipital groove?

Answer 10

Transverse humeral ligament

Question 11

This muscle does not extend the shoulder:
Posterior deltoid
Latissimus dorsi
Subscapularis
Teres major

Answer 11

Subscapularis

Question 12

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

Answer 12

Raises the ribs during inspiration

Question 12

This part of the pectoralis major can horizontally adduct the shoulder:

Answer 12

Clavicular part

Question 13

This nerve comes from the nerve roots of C5, C6, and C7.

Answer 13

Long Thoracic nerve

Question 14

This is the strongest and stiffest among the ulnar collateral ligament

Answer 14

Anterior band

Question 15

The oblique posterior band and the posterior band of the UCL supports the elbow against valgus force at this degree:

Answer 15

Beyond 90

Question 16

This head of the triceps originates in the posterior surface of the humerus (inferior to the radial groove)

Answer 16

Medial head

Question 17

The radial nerve does not innervate this muscle:
Triceps
Anconeus
Brachialis
Pronator Teres

Answer 17

Brachialis

Question 18

Which among these muscles has a different innervation:
Brachialis
Coracobrachialis
Biceps brachii
Brachioradialis

Answer 18

Brachioradialis

Question 19

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

Answer 19

The elbow should be extended so that the proximal fibers can flex the shoulder

Question 20

Carrying angle of male and female in degrees

Answer 20

Males 11-14 deg
Females 13 - 16 deg

Question 21

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

Answer 21

It is most effective as a supinator when the elbow is flexed at about a 145 degree angle

Question 22

Its nerve divides include C5, C6, C7, C8, and T1

Answer 22

Radial Nerve

Question 23

It is the largest nerve of the upper limb

Answer 23

Radial nerve

Question 24

A little farther down the arm, it passes obliquely toward lateral to run behind the humerus in its spiral groove, deep to the triceps

Answer 24

Radial Nerve

Question 25

This ligament, accompanied by the supraspinatus muscle, prevents the downward dislocation of the humeral head:

Answer 25

Coracohumeral ligament

Question 26

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.

Answer 26

Brachialis

Question 27

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.

Answer 27

Trapezius

Question 28

This nerve supplies the Serratus Anterior muscle and arises from the C5, C6, C7 roots of the brachial plexus

Answer 28

Long thoracic nerve

Question 29

This elbow flexor is innervated by the radial nerve and attaches proximally to a ridge on the humerus above the lateral epicondyle

Answer 29

Supinator
