In the classification of joints, which of the following is true?

All synovial joints are freely movable.

Which of the following is one difference between bursae and tendon sheaths?

Bursae are flattened fibrous sacs wedged between adjacent structures, while tendon sheaths are elongated fibrous sacs that wrap around tendons.

Which of the following is a hinge joint?

Which of the following is true regarding the structure indicated by the arrow in the joint depicted in A?

It becomes ossified late in adult development.

Synovial fluid is present in joint cavities of freely movable joints. Which of the following statements is true about this fluid?

Maggie is a 28-year-old Caucasian woman who has newly diagnosed rheumatoid arthritis (RA). She complains of painful, stiff hands and feet, feeling tired all the time, and reports an intermittent low-grade fever. She asks the nurse if she is going to be "crippled." How should the nurse respond?

RA is a chronic, systemic, inflammatory disorder. Inflammation occurs in the joint, and the fluid that accumulates causes swelling, stiffness, impairment of joint movement, and extreme pain.
