4.4 - The Skeletal System : Joints Lecture

Multiple Choice

Which of the following statements best explains how the structure of a joint affects its range and direction of motion?

• The structure of the bony articulation determines the directions of motion permitted.

• The tightness of soft tissues crossing the joint is the only factor affecting motion.

• All joints in the human body allow the same range of motion.
