Bone Structure Flashcards
canaliculi
Hairlike channels connecting lacunae
cancellous bone
Mesh-like, spongy bone
circumferential lamellae
Lamellae arranged parallel to surface of bone or along marrow cavity
diaphysis
Shaft of long bone
distal epiphysis
End of long bone farthest away from center of the body
endosteum
Membrane lining of inner marrow cavity
epiphyseal lines
Lines marking areas of longitudinal growth
epiphysis
End of long bone that unites to main bone later through ossification
femur
Thigh bone
fovea capitis
Ligament attachment site
greater trochanter
Projection on the upper, outer end of the thigh bone
head of femur
Highest part of the thigh bone
inner layer
Interior later of periosteum
interstitial lamellae
Bony plates filling space between haversian systems
lacunae
Small spaces occupied by osteocytes
lateral condyle of femur
Projection on lower, outer part of thigh bone
lateral epicondyle of femur
Projection above lateral condyle of femur
medullary cavity
Marrow-filled space within bone
neck of femur
Narrow process connecting parts of the thigh bone
nutrient a.
Vessel supplying medullary cavity of bone
nutrient foramen
Opening for passage of blood vessels
osteon (haversian system)
Structural unit of compact bone
outer layer
Exterior layer of periosteum
patellar groove
Smooth depression on lower end of thigh bone
