Study Notes

Bony Landmark Terms and Definitions

Meatus: Represents a body opening or passage, notably the external opening of a canal.
Fissure: Defined as any cleft or groove, particularly a deep fold within the cerebral cortex that encompasses its full thickness.
Foramen: Identified as a natural opening or passage, especially significant ones that go into or through a bone.
Fossa: A term for a trench or channel; in anatomical context, refers to a hollow or depressed area.
Sinus: Refers to a recess, cavity, or channel within a bone, including dilated channels for venous blood.
Sulcus: A term for a groove, trench, or furrow; particularly describes depressions on the brain's surface that separate gyri.
Condyle: A rounded bony projection usually intended for articulation with another bone, commonly associated with knuckle formations.
Facet: Denotes a small smooth area on a bone or other firm structure, important for joint articulation.
Head: Refers to the rounded proximal end of a long bone, also describes the end of a muscle connected to the less movable part of the skeleton.
Trochlea: An anatomical feature resembling a pulley, specifically the distal end of the humerus that articulates with the ulna.
Epicondyle: Represents a projection at the end of a bone located above a condyle, primarily serving as an attachment site for ligaments and tendons.
Linea: Denotes a narrow ridge or streak on the surface of a structure in anatomical terms.
Process: Refers to a prominence or projection that extends from a bone.
Spinous process: Part of the vertebra that projects backward from the arches, providing attachment points for back muscles.
Trochanter: Bony processes located in the upper part of the femur, serving as attachment points for various muscles.
Tubercle: A small nodular eminence, especially on a bone for tendon attachment.
Tuberosity: A prominent projection at the end of a bone, mainly for the attachment of muscles or tendons.
Crest: Refers to a projecting structure or ridge surrounding a bone, such as the iliac crest, which is the thickened upper border of the ilium.
Protuberance: Defined as a bulge, knob, or swelling that sticks out from the surface.
Prominence: Represents any protrusion or projection from a structure.
