Skeletal System 19 Bone Structure Bones contain cavities, processes, depressions, and other surface variations that serve different purposes, but are useful in identification. Terms that pertain to the different types of markings are as follows: An opening in a bone, urually round or oval. A shallow depression in a bone, oflen a socket-like feature into which another bone articulates. Sulcus A groove or furrow. A camal or long, tube-like passageway. Fissure A narrow slit. A cavity in the bone. Any prominence on a bone can be called a process. Processes exist in various shapes and sizes. Different types of processes are as follows: A rounded, knuckle-like feature that serves as an attachment point for muscles, typically just above the condyle. A large, roughened process. Tubercle A small, rounded process. A very large irregular process associated with femur. Head A process supported by a constricted section or neck. Crest A narrow ridge of bone. Spinc A sharp, slender projection. .
