Depression (kinesiology)
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).
Kinesiology
Kinesiology, also known as human kinetics is the scientific study of human movement. Kinesiology addresses physiological, mechanical, and psychological mechanisms. Applications of kinesiology to human health include: biomechanics and orthopedics, rehabilitation, such as physical and occupational...

Anatomical terms of motion
The movement of body structures is accomplished by the contraction of muscles. Muscles may move parts of the skeleton relatively to each other, or may move parts of internal organs relatively to each other. All such movements are classified by the directions in which the affected structures are moved...
