=== Walls === The following terms are used to describe the walls of a cavity: A labyrinth refers to the bony labyrinth and membranous labyrinth, components of the inner ear, due to their fine and complex structure. A sinus refers to a bony cavity, usually within the skull.
== Joints ==
A joint, or articulation is the region where adjacent bones contact each other, for example the elbow, shoulder, or costovertebral joint. Terms that refer to joints include:
articular process, referring to a projection that contacts an adjacent bone. suture, referring to an articulation between cranial bones.
== Features of long bones ==
=== Gross features === Bones are commonly described with the terms head, neck, shaft, body and base. The head of a bone usually refers to the proximal end of a long bone, but also refers to the distal end of metacarpals, metatarsals, and the ulna. The shaft refers to the elongated sections of long bone, and the neck the segment between the head and shaft (or body). The end of the long bone opposite to the head is known as the base.
=== Internal regions ===
=== Internal and external ===
The cortex of a bone is used to refer to its outer layers, and medulla used to refer to the inner surface of the bone. Red marrow, in which blood is formed is present in spongy bone as well as in the medullary cavity, while the fatty yellow marrow is present primarily in the medullary cavity.
