The sustentaculum tali is a ___________ projecting shelf.
MEDIALLY
What attaches at the calcaneus?

How would you palpate the calcaneus?
*** 3 steps
FOLLOW MEDIAL MALLEOLI DOWN TO HEEL \+ EXPLORE SHAPE AND GIRTH \+ IDENTIFY TUBEROSITY AT BASE OF HEEL
What is the general location of the cuboid?
LATERAL BONE OF THE FOOT

TUBEROSITY OF 5TH METATARSAL
What is the general location of the cuneiforms?
BETWEEN NAVICULAR AND METATARSALS
How would you describe the cuneiforms?
PART OF WHY WE ARE PLANTIGRADES (unlike dogs)
+
ROW OF 3 BONES IN FOOT, FIRST IS MEDIAL
