The actions and quantities of the dorsal and palmar interossei muscles. (200)
Bonus (if you get the question above correct): The reason for a discrepancy between these muscles and not cause a movement deficit.
What is: abduction for the dorsal interossei, of which there are 4?
What is: adduction for the palmar interossei, and there are three of these?
Bonus: What is: the body can afford to have few palmar bc the dorsal interossei can move the middle finger in either direction.

-Carpometacarpal Joints
-Intercarpal Joints
-Distal IP Joints
Bonus (100pts): These movements are allowed at the metacarpophalangeal joints
What are: gliding, gliding and sliding, and flexion and extension.
Bonus: What are circumduction, adduction, abduction, flexion and extension.
The connection between the basilic and cephalic veins on the posterior surface of the hand.
What is the dorsal venous arch?
These muscles attach to the tendons of Flexor Digitorum Profundis (in the hand). (250)
The reason why these muscles can be both flexors and extensors at the same time. (50)
What are the lumbricals?
What are: they act on different joints at once; they are anterior to the MCP joints and flex here but they are posterior to the IP joint and perform extension?
Name how the innervation of the lumbricals is divided.
What is: the lateral 2 lumbricals are innervated by the median nerve and the medial two lumbricals are innervated by the ulnar nerve?
The muscles in the thenar and hypothenar compartments.
What are the: abductor pollicis brevis, flexor pollicis brevis, and opponens pollicis?
What are the: abductor digiti minimi, flexor digiti minimi, and the opponens digiti minimi?
These structures form the anatomical snuff box.
What are the: tendons of the abductor pollicis longus, extensor pollicis brevis and extensor pollicis longus?
The radiocarpal joint is supported by these ligatments. (200)
The radiocarpal joint is a synovial joint capable of which movements? (200)
What are the radial collateral and ulnar collateral ligaments?
What are: circumduction, adduction, abduction, extension, flexion?

What are the Trapezius (middle fibers) and the Rhomboids?
What are the iliocostalis, the longissimus, and the spinalis muscles?
FLASHBACK
(200) (30seconds to answer) If you were stabbed just above the C3 vertebra, this spinal cord segment would be injured.
(200) (30 seconds to answer) The structure that fits this description: "synovial lined sac with two parts that reduces friction during abduction at the shoulder joint"
What is the C3 spinal cord segment?
What is the subdeltoid, subacromial bursa?
The common flexor synovial sheath is in this compartment of the hand. (200)
The total number of lumbricals in the BODY. (ask contestants if they are sure about their answer since I said "body" and not "hand")
What is the central compartment of the hand?
What is: 8 lumbricals total?
Name all of the carpal bones. (250) Name which ones are on the proximal row. (150) Name the ones that are on the distal row. (50)
What are the: Scaphoid, Lunate, Triquetrum, Pisiform, Hamate, Capitate, Trapezoid, Trapezium.
What are: Scaphoid, Lunate, Triquetrum, Pisiform
What are: Hamate, Capitate, Trapezoid, Trapezium
These are the boundaries of the anatomical snuff box
What are the: extensor retinaculum, Abductor pollicis longus tendon, extensor pollicis longus tendon, extensor pollicis brevis tendon?
FLASHBACK: Name the muscles of the rotator cuff (and lesser tubercle) and their innervations
What are the supraspinatus, infraspinatus (both suprascapular nerve), teres minor (axillary nerve) and the subscapularis muscle (upper and lower subscapular nerves)?
