A&P Elevations and Depressions Flashcards

Study Notes

Elevations

Condyle: Rounded, knuckle-like process found at articulating joints, allows movement between bones (e.g., mandibular condyle).
Crest: Prominent ridge along the bone's surface, serves as a site for muscle attachment (e.g., iliac crest).
Head: Enlarged, rounded portion at one end of a bone, important for forming joints (e.g., head of the femur).
Process: A bony prominence that often serves as a point of muscle attachment (e.g., mastoid process).
Spine: Sharp, slender projection from the bone, typically where ligaments or tendons attach (e.g., spine of the scapula).
Tubercle: Small, rounded projection that serves various functions, including muscle attachment (e.g., articulate tubercle).
Tuberosity: Larger, rounded projection that provides support for muscles and tendons (e.g., calcaneal tuberosity).

Depressions

Fissure: Narrow cleft or deep groove within a bone, often where nerves or blood vessels pass.
Foramen: A round or oval opening in a bone allowing for the passage of nerves and blood vessels (e.g., foramen magnum connects spinal cord to brain).
Fossa: A pit or hollow area in a bone, often serving as a space for muscles or articulating joints (e.g., mandibular fossa).
Meatus: A tube-like passageway, usually found in the skull; plays a role in auditory functions (e.g., external auditory meatus).
Sinus: A cavity within a bone, typically filled with air, that can impact weight and resonance (e.g., frontal sinus).
Sulcus: A groove or furrow, larger than a fissure; facilitates movement or accommodates structures (e.g., precentral sulcus).
