#1
Front (Question)

Anterior muscles of the arm

Back (Answer)

Biceps Brachii Coracobrachialis Brachialis

#2
Front (Question)

Nerve Supply of Anterior Muscles of Arm

Back (Answer)

Musculocutaneous nerve supplies all muscles in this group

#3
Front (Question)

Biceps Brachii

Back (Answer)

PA- Short head: coracoid process of scapula. Long head: supraglenoid tubercle of scapula DA- Radial tuberosity of radius & fascia of the forearm via the bicipital aponeurosis N/S- Musculocutaneous nerve A- supinates forearm, flexes forearm (when forearm is supinated), short head resists downwards dislocation of humerus

#4
Front (Question)

Coracobrachialis

Back (Answer)

PA- coracoid process of scapula DA- middle 1/3 of medial humerus N/S- Musculocutaneous nerve A- assists in flexion and adduction of the arm, resists shoulder dislocation

#5
Front (Question)

Brachialis

Back (Answer)

PA- distal half of anterior surface of humerus DA- coronoid process and tuberosity of ulna N/S- Musculocutaneous nerve A- Flexes forearm in all positions

#6
Front (Question)

Posterior muscles of the arm

Back (Answer)

Triceps Brachii Anconeus

#7
Front (Question)

Nerve Supply of Posterior muscles of the arm

Back (Answer)

Radial nerve supplies all muscles in this group

#8
Front (Question)

Triceps Brachii

Back (Answer)

PA- Long head: infraglenoid tubercle of the scapula. Lateral head: posterior surface of humerus, superior to radial groove. Medial head: post surface of humerus, inferior to radial groove. DA- Olecranon process of ulna N/S- Radial nerve A- Extension of forearm, long head prevents downward dislocation of humerus

#9
Front (Question)

Anconeus

Back (Answer)

PA- lateral epicondyle of the humerus DA- olecranon of ulna N/S- Radial nerve A- assists triceps in extension of forearm
