D: The central canal (or Haversian canal) of an osteon houses blood vessels.

A: A tuberosity is a rough area on the surface of a bone to which a muscle’s tendon attaches.

D: Synovial fluid is the lubricant that allows friction-free joint movement. A synarthrosis is an immovable joint

B: The occipital bone forms the base of the skull and so is above (superior) to all the others when the body is in the anatomical position.

C: Red (and/or yellow) marrow fills the medullary canal (or cavity).

B: Lacuna refers to a hole, pit, “lake” or cavity within a bone.

C: The ramus of the mandible (the only movable bone of the skull) articulates with the temporal bone at the mandibular fossa. The joint (temporomandibular join) is freely moveable, allowing us to chew and speak.

D: Sesamoid refers to like a sesame seed. Many are normal parts of anatomy that ossify within tendons (patella, fabella, hallux sesamoid).

A: It is the radius and ulna bones whose movement relative to each other produce pronation and supination.

A: C1 to C7. There are eight carpals in each wrist. There are eight cranial bones. There are five lumbar vertebrae.

C: A “long bone” has a length that is significantly longer than its width. A carpal (a bone of the wrist) is a short bone.

B: The coccyx, occipital, sternum and mandible are parts of the axial skeleton.

B: Fossa is a depression reminiscent of a (small) dinner table plate. A tuberosity is a roughening on a bone surface. The other two choices are projections above a bone surface.

D: Phalanges (singular phalanx) are the bones of the fingers or toes. Metacarpals are the bones of the hand.

A: the “greater” trochanter is a bone marking (a bump) that lies on the lateral surface of the proximal femur, while the “lesser” trochanter lies on the medial surface of the proximal femur.

C: Lacunae are the spaces within the lamellae of an osteon which enclose a bone cell (osteocyte). These cells extend their processes into the canaliculi.

B: The lateral condyle of the femur articulates with the lateral facet of the superior articular surface of the tibia, in the knee joint.

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).

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.

A: New blood cells are made in the bone marrow (haemopoiesis). Haemostasis refers to stopping bleeding.
