Abduction is an example of movement in a coronal plane about an anteroposterior axis.

true

Distally, the patella serves as a major bony landmark to which all four quadriceps muscles attach and ultimately insert on the tibial tuberosity via the patella tendon.

true

The distal malleoli of the tibia and fibula serve as pulleys for the posterior tendons to increase the mechanical advantage of the respective muscles in performing inversion and eversion actions.

true

heel strike normally occurs by landing on the heel with the foot in supination and leg in external rotation?

true

the patella serves as a pulley by improving the angle of pull with the result being a greater mechanical advantage for the quadriceps during knee extension?

true

the spine accommodates compression forces much better than tensile forces?

true
