General Anatomy of the Locomotor System

The skeleton, the supporting framework of the body, is formed by bony

and cartilaginous elements, connected by connective tissue structures.

Its parts are moved or held in defined positions or postures by the

skeletal musculature. The overarching term locomotor system includes

the skeleton and the musculature. The passive locomotor system consists

of the skeleton and its joints (articulations), while the active motor

system includes the striated muscles, the tendons, and their auxiliary

structures (muscle fasciae, bursae, tendon sheaths, and sesamoid

bones). Beside their supporting function, the skeletal elements and

their joints serve to provide levers for the muscles during locomotion.
