Skeleton and Joints

Foramen refers to a hole in a bone, while magnum means large. This large opening in the occipital bone contains the superior part of the spinal cord.

Choice A omits the axial skeleton. Choice C omits the facial bones and lumbar vertebrae. Choice D omits the ribs.

The similar terms “epiphyseal plate” refers to the region between the diaphysis and the epiphysis where growth of a long bone takes place. The “epiphyseal line” replaces the plate in adults, when the long bone has ceased to grow.

Epiphysis refers to the end of a long bone. The ends articulate with adjacent bones.

Only the femur has a structure named “trochanter”.

The pubic symphysis joins the two pelvic bones anteriorly. It is an immovable joint.

The bones of the forearm (radius and ulna) are able to pronate. That is, crossover when the forearm twists.

The metaphysis is the bony remnant of the growth plate. The cartilaginous component of the growth plate is the epiphyseal plate.

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.

Articulation means joint between bones.
