Blue box cubital fossa Flashcards
biceps reflex tests what spinal segments
C5 and C6, musculocutaneous
what structure can become inflamed during repetitive activities such as tennis, and results in microtraumas.
bicipital tendinitis
a weightlifter is pushing beyond his ability and hears a loud “pop”! what probably tore?
the tendon of the biceps
where is the best place to stop a hemorrhage of the brachial artery?
medial to the middle of the humerus
Where would a brachial hemorrhage be clamped?
distal to the origin of the deep artery
mid-shaft humoral fracture
radial nerve damage, but will not paralyze the triceps because the innervation to them (from the radial nerve) occurs higher up)
a knife wound to the axilla region would injure the
musculocutaneous n
what would happen to a musculocutaneous n injury during a knife fight?
paralysis of the coracobrachialis, the biceps brachii, and the brachialis
what two kinds of motion at the elbow joint would indicate the musculocutaneous nerve has been injured?
weakened flexion and supination
why wouldn’t flexion and supination at the elbow be entirely prohibited if the musculocutaneous n. were injured?
because supination and flexion is done by the supinator and the brachioradialis, innervated by the radial nerve
injury to the radial nerve superior to the origin of its branches to the tricepts results in
paralysis of the posterior compartment muscles, brachioradialis, supinator, extensor muscles of the wrist and fingers
what vein is a good site for the introduction of a catheter?
the median cupital vein
