Vertical angle
Strong adductor of the shoulder
Deltoid
Innervation of the serratus anterior
long thoracic nerve
one of the muscles that connects the shoulder girdle to the humerus
supraspinatus
one of the muscles that connects the trunk to the humerus

subscapularis
subscapularis
what portion of this (DELTOID) muscle acts on shoulder flexion
anterior
TRUE or FALSE: The cubital angle of males are greater than of females
false
On average, women had a greater valgus angulation than men by about 2 degrees. Two studies using a large sample of healthy subjects have shown that, regardless of gender, valgus angle is greater on the dominant arm (Neumann)
The ligament that is part of the MCL that does not provide significant articular stability.
Transverse fibers
TRUE or FALSE: The Interosseous Membrane of the forearm is taut during distraction forces
false (distraction forces: relaxed)
The ligament that wraps around the head of the radius
Annular Ligament
This is a common injury among toddlers & preschoolers that occurs when the ligament holding the radius in place at the elbow joint slips, causing the end of the radius to shift out of position
Nursemaid’s elbow
Pulled elbow
TRUE or FALSE: Valgus force will stress the ulnar collateral ligament
TRUE
Closed-packed position of the humeroulnar joint
full extension of the elbow (congruent ung articulating structure)
It acts as a supinator in extreme pronation
Brachioradialis (elbow flex, from full pronation to supinate, from full supination to pronate)
True about olecranon bursitis:
Miner’s elbow
Student’s elbow
Draftsman’s elbow
All of these
None of these
All of these
Passive Insufficiency of the triceps brachii will limit what motion?
Elbow flexion
How much stronger of a supinator is the biceps brachii when positioned at 90 degrees?
4x more than the supinator
The “workhorse” of the elbow
Brachialis
TRUE or FALSE: The proximal radioulnar joint is classified as a trochoid (pivot) joint
FALSE
It is a muscle that can also provide stability to the distal Radioulnar joint
Pronator Quadratus (Pronates forearm)
TRUE or FALSE: The humeroulnar joint is a uniaxial pivot joint
TRUE
Position where the palmar radiocarpal ligament is most taut
full ulnar deviation
It is the most commonly dislocated carpal bone
lunate
Bad force distribution
???
Which is not part of the distal carpal bones
Triquetrum
Without the articular disc, how much force will the ulna bear?
????
It is the last carpal bone to ossify
Pisiform
FOOSH stands for:
Fall on an outstretched hand
How many structures pass through the carpal tunnel?
10
It is the most commonly fractured carpal bone from FOOSH injury
Scaphoid
More likely to have impingement that can lead to pain
??
Average angular inclination of the radius in the frontal plane
??
How many phalanges do we have in a single hand?
14
These are TRUE regarding the Triangular Fibrocartilaginous Complex, except:
It binds the radius & ulna
It is located on the radial side of the wrist
It serves as a major stabilizer of the distal radioulnar joint
None of the above
It is located on the radial side of the wrist
????
TRUE or FALSE: The articular surfaces of the distal carpal row favors wrist extension & radial deviation which is opposite for the radioulnar joint.
TRUE
The Goniometer is an instrument used commonly by Physical Therapists and Prosthetists to assess a joint’s range of motion (ROM). In order to assess the wrist’s ulnar & radial deviation, the goniometer’s vertex (axis/fulcrum) must be placed on the center-most carpal bone. All of the statements regarding this carpal bone is true, except:
It is the largest carpal bone
It is the 1st carpal bone to ossify
It is lateral to the hamate
It is palpated by asking the patient to extend the wrist
It is palpated by asking the patient to extend the wrist???
All structures pass through the carpal tunnel, except:
FPL, Median Nerve, FCU, FDS
FCU
The muscle responsible for flexing the digits at the PIP joint
FDS
It is responsible for 50% of the hand’s function (Brunnstrom)
Thumb
TRUE or FALSE: Ape hand deformity is due to the wasting of the thenar muscles
TRUE
TRUE or FALSE: The hand’s grip is weakened when the wrist is flexed during finger flexion
TRUE
The roof of the carpal tunnel
flexor retinaculum
It is the muscle with a tendon that becomes very prominent during hand opposition
PL
(Palmaris longus)
TRUE or FALSE: The palmar interossei of the hand is responsible for abduction of the digits
FALSE
What muscle is being tested in Maudsley’s test?
EDC
Trigger Finger commonly affects what digits?
3rd & 4th
TRUE or FALSE: Wrist drop occurs in radial nerve palsy
TRUE
TRUE or FALSE: The FDP is a thicker muscle, & shorter tendon than the FDS
FALSE
It is known to be the most commonly affected muscle in lateral epicondylitis
ECRB
This muscle can flex the DIP joints of the digits
FDP
What extensor tunnel does the ECRL & ECRB pass through?
Tunnel 2
