Dorsiflexion is associated with which of the following joints?

Ankle joint

The pelvic girdle allows for a greater range of motion. The pectoral girdle offers more strength.

Both statements are false.

Which of the following are TRUE statements?

Structurally, joints are classified based on the type of material that binds the bones together. Structurally, joints are classified based on whether or not they have a synovial cavity.
