Surface Contours Of The Bone Flashcards
Head
Round & smooth
Strongly convex articulate (relating to joints) projecting process
Situated on the end of long bones
e.g. head of humerus and femur
Condyle
Smooth & convex
Knuckle-like (protruding mass) articular projection
Situated at the extremities of long bones
E.g. condoles of humerus and femur
Facet
Small, smooth articular surface
May be flat, concave or convex
E.g. articular facet of radius, cranial and caudal articular facets of the vertabrae
Epicondyle
Non-articulating
Smaller, roughened and enlarged projection above condyle
Attachment sites for muscles and ligaments
Proces
Non-articulating
Vague term generally applied to a projection
E.g. acromian process, spinous process
Trochanter
Non-articulating
Blunt projection
Specialised term form a few tuberosities on the femur
E.g. trochanter major or lesser trochanter of the femur
Tubercle
Non-articulating
Small knob-like, rounded process
Tuberosity
Large, often rounded, usually roughened process
Point of attachment of ligaments and/or tendons
Generally a tubercle is larger and more prominent than a tuberosity
Crest
Prominent linear sharp border or ridge
Line
Less prominent, very faint ridge
Spine
Sharp, slender process or elongated thin shelf like projection
Neck
Constricted attachment between articulating head and shaft of the bone is called neck
E.g. neck of humerus and neck of femur
Non- articulating depression
Mainly provide an area for the passage of blood vessels and other soft tissue
Fovea: small, pit-like landmark or depression
Fossa: larger, basin-like depression
Notch: non-articular depression which is usually a “C” or “U” shaped
Groove: a furrow-like opening or sulcus that accommodates soft tissue structures such as blood vessels, nerves or tendons
E.g. intertubercular groove of the humerus through which the tendon or origin of the bicep brachii passes
Acetabulum
Smooth and deep articular depression
Trochlea
Large, pulley-like structure
Articular in structure
