hi guys! wanted to give you guys a bone review, so today I’m doing the carpals!! the carpals are the bones of your wrist; there are eight. the easiest way to remember their order is this jingle: 

So Long To Pinky, Here Comes The Thumb

Scaphoid, Lunate, Triquetral, Pisiform (bottom row, right to left in anatomical position)

Hamate, Capitate, Trapezoid, Trapezium (top row, left to right) 

here are some helpful tips for identifying and siding!

Scaphoid  

Articulations: capitate, radius, lunate, trapezium 

Looks like a snail  

When the concavity is facing toward you, the tubercle rises in the side that it is

Lunate "the moon"

Articulations: capitate, radius, scaphoid, triquetral, hamate  

With concavity toward you, articular facet is on the side it's from

Triquetral  

Articulations: pisiform, hamate, lunate 

Hold the "pinchable" common border.. The pisiform facet rises to the side it's from 

Pisiform "the pea"

Articulations: triquetral  *almost impossible to side

Trapezium  

Articulations: scaphoid, trapezoid, MC I, MC II 

Tubercle/crest facing you and distal "(aim the crossbow")

Groove aside the "eyepiece" is on side it's from 

Trapezoid "the boot"

Articulations: scaphoid, trapezium, MC II, capitate 

With "zipper" facing you.. The toe points to the side it's from 

Capitate "darth vader"

Articulations: scaphoid, hamate, MC II, MC III, lunate, trapezoid 

Face" is convex, concave "helmet" sets on the side the bone is from 

Hamate  

Articulations: triquetral, capitate, MC IV, MC V, lunate
