bone markings

notch

a V-like depression in the margin or edge of a flat area

angle

a corner

process

a raised area or projection

epiphysis

both ends of a long bone, made of cancellous bone filled with marrow

epicondyle

bump near a condyle; often gives the appearance of "bump on a bump"; for muscle attachment

sinus

cavity of a bone

ramus

curved portion of a bone, like a ram's horn

periosteum

dense, white fibrous membrane that covers bone and attaches tendons firmly to bones

fossa

depression; often receives an articulating bone

head

distinct epiphysis on a long bone, separated from the shaft by a narrowed portion (or neck)

margin

edge of a flat bone or flat portion of edge of a flat area

facet

flat surface that forms a joint with another facet or flat bone

sulcus

groove or elongated depression

trochanter

large bump for muscle attachment (larger than tubercle or tuberosity)

articular cartilage

layer of hyaline cartilage that covers the articular surface of epiphysis

fissure

long, cracklike hole for blood vessels and nerves

diaphysis

main shaft of long bone

crest

moderately raised ridge; generally a site for muscle attachment

tuberosity

oblong, raised bump, usually for muscle attachment; small tuberositys is called Tubercle

foramen

round hole for vessels and nerves (foramina)

condyle

rounded bump; usually fits into a fossa on another bone, forming a joint

line

similar to a crest but not raised as much ( is often rather faint)

spine

similar to a crest but raised more; a sharp, pointed process; for muscle attachment

body

the main portion of bone

endosteum

thin epithelial membrane that lines medullary cavity

meatus

tubelike opening or channel

medullary cavity

tubelike, hollow space in diaphysis; filled with yellow marrow in adult
