Anatomy of the long bone

proximal epiphysis

rounded end of long bone, located closest to the center of the body or torso

Diaphysis

long central shaft of the long bone, connects the two rounded ends.

distal epiphysis

rounded end of long bone located farthest away from the center of the body

articular cartilage

smooth white tissue that covers the ends of bones where they meet to form a joint

periosteum

dense fibrous membrane that covers outer surface of most bones.

endosteum

thin layer of connective tissue that lines the inner surfaces of bones including the marrow cavity, spongy bone and internal canals.

yellow bone marrow

type of soft fatty tissue found in the central cavities of long bones that primarily stores energy and contains specialized stem cells.

medullary cavity

hollow central space inside the diaphysis (shaft) of the long bones

epiphyseal line

solid bony remnant of the epiphyseal plate (growth plate) forms when a long bone stops growing in length

spongy bone

lightweight porous inner tissue found inside most bones
