Regarding pronator teres which of the following statements is correct?
It forms the lateral border of the cubital fossa
It arises from the coronoid process and lateral epicondyle.
The Median nerve passes deep to both heads
It is the most lateral of the superficial flexors of the forearm
Regarding the radial nerve which statement is incorrect?
It passes anterior to the lateral epicondyle of the humerus
Sensory loss from injury to the superficial radial nerve will usually result in loss of sensation over the entire thumb
It is the larger terminal branch of the posterior cord of the brachial plexus
Injury to the radial nerve from fracture of the shaft of the humerus will result in wrist drop
Regarding the blood supply of the forearm
The radial artery is the larger of the terminal branches of the brachial artery
The radial artery runs under brachialis as it leaves the cubital fossa
The radial artery has just one named branch proximal to the carpal braches
The radial artery has no involvement in the elbow anastomotic network
The median nerve
Supplies flexor carpi ulnaris and half of flexor digitorum profundis
Gives rise to most of its braches in the upper arm
May be compressed between the two heads of pronator teres
Enters cubital fossa lateral to the brachial artery
Supination of forearm with the elbow extended is brought about mainly by?
Biceps brachii
Supinator
Brachioradialis
Brachialis

Lesser tubercle
Which muscle does the ulnar nerve pierce in the forearm?
Flexor carpi radialis
Flexor carpi ulnaris
Flexor digitorum superficialis
Pronator teres
What is the action of anconeus?
Abducts the ulna in pronation
Extension of the wrist
Supination of the forearm
Flexion of the elbow
What is the common site of origin for posterior forearm muscles?
Olecranon
Deltoid tubercle
Damaged of the ulnar nerve at the Elbow causes all of the following EXCEPT :-
paralysis of Flexor carpi ulnaris
abduction and adduction of the fingers cannot occur.
