arm, cubital fossa, forearm (TF) Flashcards
(50 cards)
The humerus is the longest bone in the upper limb and articulates with the scapula at the glenohumeral joint.
true
The biceps brachii muscle inserts on the radial tuberosity.
False** (The biceps brachii inserts on the radial tuberosity, but it also has attachments to the forearm fascia.)
The triceps brachii muscle is the primary flexor of the elbow joint.
False** (The triceps brachii is the primary extensor of the elbow joint.)
The brachial artery is the main blood supply to the upper limb and continues as the radial and ulnar arteries in the forearm.
true
The median nerve innervates the biceps brachii muscle.
False** (The biceps brachii is innervated by the musculocutaneous nerve.)
The ulnar nerve passes through the cubital tunnel and innervates the intrinsic muscles of the hand.
true
The radial nerve innervates the extensor muscles of the forearm.
true
The brachioradialis muscle is innervated by the median nerve.
False** (The brachioradialis is innervated by the radial nerve.)
. The radius and ulna are the two bones of the forearm, with the radius being medial and the ulna being lateral
*False** (The radius is lateral, and the ulna is medial.)
The axillary nerve supplies the deltoid muscle.
False** (The axillary nerve supplies the deltoid muscle; the radial nerve supplies the deltoid as well.)
The radial artery runs along the lateral side of the forearm and gives off the profunda brachii artery.
False (The profunda brachii artery is a branch of the brachial artery, not the radial artery.)
The ulnar artery is the larger of the two terminal branches of the brachial artery.
False (The radial artery is usually larger than the ulnar artery.)
The musculocutaneous nerve innervates the coracobrachialis and brachialis muscles.
true
The median nerve passes through the carpal tunnel and innervates the thenar muscles.
true
The radial nerve is responsible for the sensation on the dorsal aspect of the hand.
true
The cubital fossa is located on the posterior aspect of the elbow joint.
*False** (It is located on the anterior aspect of the elbow joint.)
The lateral border of the cubital fossa is formed by the brachioradialis muscle.
true
The brachial artery bifurcates into the radial and ulnar arteries at the apex of the cubital fossa.
true
The median nerve exits the cubital fossa by passing between the two heads of the pronator teres
true
The radial nerve is considered a major content of the cubital fossa.
False (The radial nerve is in the vicinity but not a major content of the cubital fossa.)
The bicipital aponeurosis forms part of the roof of the cubital fossa and protects the median nerve and brachial artery.
true
The floor of the cubital fossa is formed by the brachialis muscle proximally and the supinator muscle distally.
true
The median cubital vein is a common site for venipuncture and is located within the roof of the cubital fossa.
true
The ulnar nerve passes through the cubital fossa and is palpable in this region.
*False** (The ulnar nerve does not pass through the cubital fossa.)
