Nerves
This nerve provides the motor innervation to all the muscles in the anterior arm
What is the musculocutaneous nerve?
This is the major artery of the arm, found in the anterior compartment
What is the brachial artery?
This muscle is both a powerful flexor of the arm at the elbow joint, and the most powerful supinator of the forearm
What is the biceps brachii muscle?
Lies within the radial groove at the posterior aspect of the humerus
What is the radial n. and profunda brachii artery?
This nerve innervates the muscles in the posterior compartment of both the arm and forearm
What is the radial nerve?
This vein, located in the cubital fossa, connects the cephalic and basilic veins, and is a common site for venipuncture
What is the median cubital vein?
This is the only muscle of the posterior compartment of the arm
What is the triceps brachii muscle?
This is the distal attachment for the tendon of the biceps brachii
What is the radial tuberosity?
This nerve innervates most of the muscles of the posterior compartment of the forearm
The deep branch of the radial nerve? (which originates from the radial nerve in the lateral wall of the cubital fossa deep to the brachioradialis muscle and becomes the posterior interosseous nerve after emerging from between the superficial and deep layers of the supinator muscle in the posterior compartment of the forearm)
What are the ulnar artery and radial artery?
These are the muscles make up the superficial layer of muscles of the forearm and originate from the medial epicondyle of the humerus
What are the flexor carpi ulnaris, plamaris longus, flexor carpi radialis, and pronator teres?
This nerve is at risk for injury with fracture of the medial epicondyle
What is the ulnar nerve?
A patient presents with wrist drop, and sensory loss at the dorsum of the lateral hand following a mid-shaft humerus fracture, indicating damage to this nerve
What is the radial nerve?
The predominant blood supply of the posterior compartment of the forearm come from these arteries
What are branches of the radial, posterior interosseous, and anterior interosseous arteries?
The "Popeye" sign is characteristic of the rupture of this tendon
What is the tendon of the long head of the biceps brachii muscle (at the supraglenoid tubercle of the scapula, which is the most common tendon rupture of the upper limb)
These nerve and artery are at risk with a fracture of the surgical neck of the humerus
What are the axillary nerve and posterior circumflex humeral artery?
A 14 year old male patient presents with difficulty flexing the IP joint of the thumb and distal IP joint of the index finger. Upon exam, patient is unable to make the "OK" sign. History reveals, patient had a forearm cast removed the day prior. Sign, symptoms, and history point to injury of this nerve
What is the anterior interosseous nerve (the largest branch of the median nerve located in the anterior compartment of the forearm)
A patient presents following punching their hand through a glass window. These arteries are most at risk due to their superficial position.
What are the radial and ulnar arteries? (dual supply to hand means that one can typically be tied off by surgeon without consquence)
This forearm muscle has two heads, the humero-ulnar head and the radial head, and functions to flex the IP joints of the index, middle, ring, and little fingers
What is the flexor digitorum superficialis?
This nerve and artery at risk of injury with a fracture of the shaft of the humerus
What are the radial nerve and profunda brachii artery?
