Question 2 of 5
A joint cavity filled with fluid gives synovial joints their freedom of movement.
Correct Answer: A
Rationale: Synovial joints (e.g., knee) have a cavity with synovial fluid, reducing friction and enabling free movement. This is accurate, making 'True' correct.
Question 3 of 5
Which one of the following statements is accurate for the Appendicular Skeleton?
Correct Answer: D
Rationale: The appendicular skeleton has 126 bones (upper/lower limbs, pectoral/pelvic girdles) at the body’s extremities. The axial skeleton has 80 bones centrally. '100' and '80 at extremities' are incorrect, making 'Consists of 126 bones which are located at the extremities of the body' accurate.

Which one of the following statements is the Shape function of the skeletal system?
Correct Answer: D
Rationale: The shape function defines the body’s form (e.g., height, width), varying with growth. A is support, B is blood production, and C is protection, making 'The skeleton gives the body shape, which changes with growth and makes you tall or short' the shape function.
