The swivelling of the foot to the medial and lateral directions. C. The twisting of the wrist while the elbow is held motionless. D. The rotation at the shoulder that causes the arm to describe a cone shape. C: Pronation occurs when the radius is moved from a position parallel to the ulna to one where it crosses over the ulna, and supination is the return motion (may be thought of as the action we perform when turning off a wall-mounted tap). 19 / 20 19. One of the functions of bones is to make red blood cells. What is this process known as? A. Haemolysis B. Haemopoiesis C. Haematuria D. Haemostasis B: Haemopoiesis (or haematopoiesis) refers to making all of cellular components of blood. The other (wrong) choices are, respectively, the rupturing (lysis) of RBC, blood in the urine and the process by which the body causes bleeding to stop. 20 / 20 20. Which of the following is a function of the skeletal system? A. Haemopoiesis B. Haemostasis C. Peristalsis D. Glycogenolysis A: New blood cells are made in the bone marrow (haemopoiesis). Haemostasis refers to stopping bleeding.
