Bone Markings Flashcards
What is a facet
Shallow convex or concave surface where two bones articulate
What is a fossa
Indentation in a bone into which another structure fits
What is fovea
A shallow pit
What is a groove (salcus)
Long indentation along which a narrow structure travels
What type of bone marking are fovea, groove (sulcus), fossa, and facet
Depressions: clefts of varying depth in a bone; located where a bone meets another structure such as another bone or blood vessel
What type of bone marking are canal (meatus), fissure, and foramen (plural, foramina)
Openings
What do openings do
They are holes that allow blood vessels and nerves to travel through a bone; permit access to the middle and inner ear; encase delicate structures and protect them from trauma
What is canal (meatus)
Tunnel through a bone
What is fissure
Narrow slit in a bone or between adjacent parts of bones
What is foramen (plural, foramina)
Hole in a bone
What type of bone markings are condyle, crest, head, tubercle and tuberosity, epicondyle, process, spine, protuberance, trochanter, and line
Projections
What do projections do
Bony extensions of varying shapes and sizes: some provide locations for attachment of muscles, tendons, and ligaments; some fit into depressions of other bones to stabilize joints
What is condyle
Rounded end of a bone that articulates with another bone
What is crest
Ridge or projection
What is head
Round projection from a bone’s epiphysis
What is tubercle and tuberosity
Small, rounded bony projection: a tuberosity is a large tubercle
What is epicondyle
Small projection usually proximal to condyle
What is process and spine
Process is a prominent bony projection
Spine is a sharp process
What is protuberance
Outgrowth from a bone
What is trochanter
Large projection found only on the femur
What is line
Long, narrow ridge
