appendicular skeleton
Concentric circles or rings of lacunae found in bone tissue
lamellae
Complex consisting of a Haversian canal and the lamellae surrounding it
osteon

lacunae
Refers to the hip region
pelvic
Shaft of a long bone; composed of compact bone
diaphysis
Canals in bone tissue that carry blood vessels and nerves

Covers the epiphyses for smooth movement
articular cartilage
End of a long bone; composed mostly of spongy bone
epiphysis

axis
