Depression (kinesiology)

From Wikipedia, the free encyclopedia

Depression, in kinesiology, is the anatomical term of motion for movement in an inferior direction.

It is the opposite of elevation.

This term is often applied to the shoulders (e.g. dropping them to a normal condition after shrugging them would be depression).
