Study Notes
Bone Markings Overview
- Bone markings are important anatomical features that indicate various projections, depressions, and openings on bones relevant for muscle attachment, joint formation, and passageways for nerves and blood vessels.
Key Terms in Bone Markings
- Process: Refers to any bone prominence that serves as an attachment point for muscles or ligaments.
- Tuberosity: A large rounded projection, often serving as an attachment site for muscles.
- Crest: A narrow, ridge-like bone feature that is usually prominent, providing stability and muscle attachment.
- Trochanter: A very large, blunt, irregularly shaped process; specifically exists on the femur, crucial for muscle leverage.
- Line: A narrow ridge that is less prominent compared to a crest, serving similar attachment functions.
- Tubercle: A small rounded projection or process, often associated with muscle attachment.
- Epicondyle: A raised area located on or above a condyle, important for muscle and ligament attachment.
- Spine: A sharp, slender projection that can provide leverage or attachment point for muscles.
- Head: A bony expansion at the end of a bone that is supported by a narrow neck, often fits into a joint.
- Facet: A smooth and nearly flat surface that serves as an articulation point between bones.
- Condyle: A rounded articulating projection that forms joints with other bones.
- Meatus: A canal-like passageway that can serve as a route for nerves or blood vessels.
- Sinus: A cavity within a bone that is filled with air and lined with mucous membrane, plays a role in reducing bone weight and resonating sound.
- Fossa: A shallow, basin-like depression on a bone, typically serving as an articular surface for joints.
- Groove: A furrow or indentation that provides a pathway for nerves and blood vessels.
- Fissure: A narrow, slit-like opening in a bone, allowing for the passage of structures.
- Foramen: A round or oval opening through a bone that permits the transit of nerves, blood vessels, or ligaments.
- Notch: An indentation at the edge of a bony structure that may serve as a passageway or articulating surface.
