joints

Open Ended

Why are joints important for the human body, and what roles do they play beyond enabling movement?

Multiple Choice

Which of the following best describes fibrous joints?

• They are freely movable and have a complex structure.

• They are held together by cartilage and allow slight movement.

• They are found between bones in close contact and are mostly immovable.

• They permit shape changes during childbirth.
