Skeleton and Joints

Osteons are the structural units of compact bone, and each one surrounds a channel, called a Haversion canal, which contains blood vessels.

New red and white blood cells are made in the bone marrow (haemopoiesis). Haemostasis refers to stopping bleeding.

A facet is a shallow dish-like depression in a bone that receives a projection such as a condyle, from another bone. Foramina are holes in bone through which blood vessels or nerve pass. A phalange is a finger or toe bone.

Hyoid is in the neck. Choice A and B are in the skull. Femoid is not a bone.

Hyaline cartilage is very smooth which (along with synovial fluid) makes the movement of the articulating bones almost friction-free.

The manubrium and xiphoid process (and the body) are all parts of the sternum.

Hyaline cartilage is very smooth and, by covering the articulating surfaces of bones, ensures that the joint moves without noticeable friction.

Compact bone does contain osteons, but not trabeculae (which occur in cancellous bone).

The fluid is synovial fluid. Ball and socket joints are synovial, but are only one type of synovial joint.

The manubrium, coccyx and sacrum are within the axial skeleton.
