memorize

Section 3

Question Answer
Scaphoidlargest in proximal and most frequently fx
Scaphoid articulates w/Radius
Lunate articulates w/Radius
Triquetrum articulates with what three?Pisiform, hamate, and lunate bones
PisiformSmallest carpal bone best seen in carpal sulcus view
Pisiform articulates w/Triquetrum
Distal articulate w/Metacarpals
TrapeziumBetween scaphoid and 1st MC
TrapezoidSmallest bone in distal row
CapitateLargest carpal bone
HamateHook like process called hamulus
memorize

Section 4

Question Answer

What is best demonstrated with the Carpal sulcus view?Pisiform and Hamate
What passes through this tunnel or canal?Major nerves and tendons
Radial deviationTurn hand toward thumbs
Ulnar deviation Turn hand toward pinky
What can you not see well on a lateral view?Carpals; they are superimposed
memorize

Section 5

Question Answer
RadiusThumb side/ lateral
UlnaPinky side/ Medial

Radial styloidExtends more distally
memorize

Section 6

Question Answer
Ulnar notchwhere ulna fits on radius
Head of radiusProximal end of radius
Head of radius articulates w/Humerus
Body of radiusLong mid bone
Radial tuberosityDistal to head and neck, oval process
memorize

Section 7

Question Answer
Ulnalonger than radius primarily involves elbow
Olecranon processmost proximal, posterior of elbow, beak like
Coronoid processmost anterior and more distal
Coronoid tubercleOn medial margin of coronoid process
Trochlear notchHumerus sits inside (big depression)
Radial notchSm. depression on lateral side of ulna
Radial notch articulates w/head of radius
What does the radial notch allow?Pronation of forearm; radius and ulna cross over in pronation
