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

True

Both the size and the shape of bones can limit or allow movements.

True

Collagen in bone provides flexibility and strength to resist tension.

True

Diarthroidal joints are also known as synovial joints.

True
