The Pits
The axilla is the upper limb homolog to this structure in the lower limb.
What is the femoral triangle?
This covers the neurovasculature of the cubital fossa.
What is the bicipital aponeurosis?
These fibers of trapezius contribute to upward rotation of the scapula.
What are the upper and lower fibers?
This joint is the only articulation between the upper limb and the axial skeleton. (Bonus 100 points if you can also give the type of joint)
What is the sternoclavicular joint? (Bonus: synovial, saddle)
These ventral rami are dermatome only.
What is C4 and T2?
These muscles make up the posterior wall of the axilla.
What are teres major, latissimus dorsi, triceps long head, and subscapularis?
The biceps brachii muscle crosses over these three joints.
What are the glenohumeral, elbow, and proximal radioulnar joints?
Brachioradialis DTR primarily tests this nerve root.
What is C6?
The AC joint is primarily supported by this structure. (Bonus 100 points if you can name the injury/condition caused when this structure is torn.)
What is the coracoclavicular ligament? (Bonus: shoulder separation)
The radial artery gives off this artery before making its way to supply the palm.
What is the dorsal carpal artery?
This makes up the apex of the axilla and allows for communication between the neck and the axilla.
What is the cervicoaxillary canal?
These run in between the two heads of flexor digitorum superficialis.
What are median nerve and ulnar a/v?
This bursa is a common site for bursitis, often resulting from a fall on to the elbow. (Bonus 100 points for the the name of the other bursa)
What is the subcutaneous olecranon bursa? (Bonus: subtendinous olecranon bursa)
This injury can compromise the axillary nerve, resulting in a flattened deltoid due to paralysis. (Bonus 100 points for the most common direction)
What is shoulder dislocation? (Bonus: anteroinferior)
The ulnar nerve passes through this structure between the two heads of this muscle.
What is the cubital tunnel in between the heads of flexor carpi ulnaris?
This is a continuation of the prevertebral layer of deep cervical fascia. It contains the proximal parts of the axillary vessels and the brachial plexus.
What is the axillary sheath?
Only these two digits have synovial sheaths that are continuous with the synovial sheath in the carpal tunnel.
What are the first and fifth digits?
This structure acts as a pulley for the tendon of extensor pollicis longus.
What is Lister's tubercle (or the dorsal radial tubercle)?
All the CMC joints are synovial plane joints except for this CMC joint. (Bonus 100 points for the type of joint it is)
What is the 1st CMC joint? (Bonus: synovial, saddle)
I burned the tips of my first three digits when grabbing a dumpling off a hot frying pan. This/These nerves made the pain known.
What is median nerve?
The axillary nerve and posterior circumflex humeral a/v travel through this space.
What is the quadrangular space?
These two pulleys in the fibrous digital sheath are important in preventing bowstringing of the flexor tendons during digit flexion.
What are A2 and A4 annular pulleys?
This condition is a result of inflammation of the synovial sheaths in the 1st extensor compartment at the wrist. It causes pain near the base of the thumb, especially when trying to make a fist. (Bonus 100 points for the tendon(s) found in the 1st compartment)
What is De Quervain's tenosynovitis? (Bonus: tendons of abductor pollicis longus and extensor pollicis brevis)
The distal radiocarpal joint is a modified pivot joint that allows for pronation and supination. This ligament makes sure the hand follows the forearm when supinating.
What is the palmar radiocarpal ligament?
I also burned the back of my hand across the MCP joints of digits 2-5 somehow... This/These nerves were responsible for making the pain known.
What are the superficial radial nerve and dorsal cutaneous branch of ulnar nerve?
