meatus | tubelike passageway within a bone (e.g. auditory meatus of the temporal bone) |
sinus | cavity within a bone (e.g. frontal sinus) |
fossa | simple depression or hollowing in or one a bone (e.g. mandibular fossa of the temporal bone) |
sulcus | groove that may contain a blood vessel, nerve, or tendon (e.g. malleolar sulcus of the tibia) |

epicondyle | second protrusion above a condyle (e.g. lateral epicondyles of the femur) |
line | less prominent ridge on a bone (e.g. linea aspera of the femur) |
tubercle | small, round protrusion (e.g. greater tubercle of the humerus) |
tuberosity | large, round, and usually roughened protrusion (e.g. ichial tuberosity of the coxal bone) |
