Bone Markings

Bone Markings

3 types: depressions, openings and projections

Depressions

Bone marking category; clefts where one bone meets another sturcutre (blood/blood vessel)

Openings

Holes taht allow blood vessel and nerves to travel through bone; allow access of inner ear

Projections

Bony extensions of different shpaes and sizes to provide locations for attachemnt (muscls,tendons, and ligaments)

, fit into depressions or other bones for stabilization

Facet

Type of depression that is a shallow convex or concave surface for two bones to articulate

Fossa/fossae

type of depression, indentation in a bone to fit another strucutre

fovea

type of depression, shallow pit

groove

type of depression, long indentation along whihc a narrow structure travels

canal

type of opening; tunnel through abone

fissure

type of opening; narrow slit in a bone or between adjacent parts of bones

foramen/foramina

type of opening; hole in a bone

crest

type of projection; narrow ridge or raised edge

head

type of projection; round projection from a bone’s epiphysis to form a joint

tubercle and tuberosity

type of projection; small, rounded bony projection; tuberosity is a large tubercle

epicondyle

type of projection; small projection usually proximal to a condyle

process

type of projection; prominent bony bump (in scapula, coracoid process)

spine

type of projection; sharp process(in scapula, spine)

protuberance

type of projection; outgrowth from a bone (in occipital bone, external occipital protuberance)

trochanter

type of projection; large proejction only on femur to attach hip and thigh muscles

Line

type of projection; long, narrow ridge (on femor, linea aspera)

Notch

Type of depression; v-like shaped and usually on edges of bone

Condyle

Type of projection; rounded, smooth and knuckle-shaped to articulate with another bone
