toward the feet

cephalad (cranial)

toward the head

contralateral

a structure on the opposite side of the body

deep

away from the surface or the skin

distal

farther away from the heart; farther away from the origin; farther away from the point of attachment

dorsal

related to the back of the body; toward the back of the body

inferior

toward the feet; a structure lower than another structure

ipsilateral
