Muscle
This anterior arm muscle flexes the elbow and supinates the forearm.
What is the biceps brachii?
The biceps brachii inserts at this tuberosity on the radius and into the bicipital aponeurosis.
What is the radial tuberosity?
This ligament holds the radius in place during pronation and supination.
What is the annular ligament?
This major artery runs beneath the clavicle and becomes the axillary artery at the lateral border of the first rib.
What is the subclavian artery?
This nerve innervates the anconeus and triceps brachii.
What is the radial nerve (C6, C7, C8)?
The long head of this muscle also assists with shoulder extension and adduction.
What is the triceps brachii?
This groove between the tubercles of the humerus houses the tendon of the long head of the biceps brachii.
What is the bicipital groove?
This ligament goes from the coracoid process to the greater tubercle of the humerus.
What is the coracohumeral ligament?
This continuation of the axillary artery runs down the arm and divides near the cubital fossa.
What is the brachial artery?
This nerve innervates all the muscles of the anterior compartment of the arm (no numbers needed for this one).
What is the musculocutaneous nerve?
The muscle that assists triceps in elbow extension
What is the anconeus?
The brachialis inserts at these ulnar landmarks.
What is the coronoid process and ulnar tuberosity?
This ligament forms an arch above the shoulder joint and prevents superior displacement of the humeral head.
What is the coracoacromial ligament?
These two arteries divide from the brachial artery near the cubital fossa.
What are the radial and ulnar arteries?
From an anterior view, in anatomical position, this cutaneous innervation of the upper extremities dermatomal pattern affects the lateral aspect of the "arm" (list the spinal nerve number).
What is C5?
This muscle does shoulder flexion, shoulder adduction, and stabilization of the glenohumeral joint.
What is the coracobrachialis?
The long head of the triceps and the anconeus both share this general insertion area.
What is the olecranon of the ulna?
This ligament resists varus stress (adduction) at the elbow and stabilizes the lateral side.
What is the radial (lateral) collateral ligament?
This deep vein accompanies the axillary artery and drains blood from the arm into the subclavian vein.
What is the axillary vein?
These two nerves of the brachial plexus split off at the upper trunk (don't forget the numbers!).
What is the suprascapular nerve (C5,C6) and subclavian nerve (C5,C6)?
This muscle is the primary flexor of the elbow joint.
What is the brachialis?
The rounded distal humeral structure articulates with the head of the radius.
What is the capitulum?
This ligament holds the long head of the biceps tendon in the groove.
What is the transverse humeral ligament?
This superficial vein runs along the lateral side of the arm, passes between the deltoid and pectoralis major, and drains into the axillary vein.
What is the cephalic vein?
This nerve passes through the coracobrachialis muscle before innervating the anterior compartment of the arm (don't forget the numbers of the nerve too!).
What is the Musculocutaneous Nerve (C5, C6, C7)?
