Exam 2 Review:  Chapter 6:  Bone Markings

tuberosity - A projection or protuberance, especially one at the end of a bone for the attachment of a ligament, a muscle or a tendon.

crest - a ridge or elongated prominence on a bone, for the attachment of a ligament, a muscle or a tendon.

trochanter - One of two bony processes near the head of the femur, the outer being called the greater trochanter, and the inner being called the lesser trochanter; they are anchors for the attachment of ligaments and muscle tendons for muscles which move the femur.

line - A narrow ridge of bone; less prominent than a crest, for the attachment of a ligament, a muscle or a tendon.

tubercle - A small rough rounded projection or process of bone, for the attachment of a ligament, a muscle or a tendon.

condyle - A smooth rounded prominence at the end of a bone, most often lined by hyaline cartilage and for articulation with another bone; sometimes also applied to the concave articular surface of the opposing bone.

epicondyle - A rough rounded projection at the end of a bone, located on or above a condyle (a type of synovial joint surface) and usually serving as a place of attachment for ligaments and tendons.

spine - a sharp, slender, often pointed projection of bone for the attachment of a ligament, a muscle or a tendon.

head - A bony expansion carried on a narrow neck at the end of a bone, most often lined by hyaline cartilage and for articulation with another bone.

facet - A small, smooth, flat surface on a bone, most often lined by hyaline cartilage and for articulation with another bone; or a small, smooth, flat surface on a tooth.

ramus -- A bony process extending like a branch or arm from a larger bone, especially the ascending part of the lower jaw that makes a joint at the temple.

meatus - A body opening or tubular passage, such as the opening of the ear or the urethral canal.

sinus -

1. A dilated channel or receptacle within the circulator system containing chiefly venous blood.
2. Any of various air-filled cavities in the bones of the skull, especially one communicating with the nostrils; e.g., the sinuses in the ethmoid, frontal, maxillary, sphenoid and temporal bones.

fossa - A small basin-like cavity or depression, as in a bone; some are articular surfaces lined with hyaline cartilage, others are the anchors for the rounded body of a muscle.

groove - A long narrow furrow or channel on the surface of a bone through which a blood vessel or nerve passes.

fissure - A normal groove or furrow, as in the liver or brain, that divides an organ into lobes or parts; a narrow slit-like opening through a bone through which a blood vessel or nerve passes.

foramen - An round or oval opening or orifice in a bone through which a blood vessel or nerve or rarely some other structure(s) passes .
