Side ASide B
Periosteum
fibrous membrane which covers the bone
Articular cartilage
a thin layer of cartilage that covers the epiphyseal surface
Endosteum
membrane lining the marrow cavity
Epiphyseal plate
a layer of white hyaline cartilage at the junction of the epiphysis and diaphysis. Place where cartilage is replaced by bone cells (ossification) and is replaced by epiphyseal line....
Haversian canal
longitudinal canal in the center of haversian systems; contains blood vessels, nerves, and lymphatics
Lamellae
concentric rings of calcified matrix around the Haversian canal
Lacunae
cavities between lamellae that contain bone cells
Osteocytes
mature blood cells located within a lacunae
Canaliculi
small canals that radiate from the Haversian canal and interconnect lacunae with each other
why is bone classified as connective tissue?
because it is highly vascular, it supports, and it has a strong matrix containing osteocytes.
Route taken by blood through a bone to an osteocyte in a lacunae

hydroxyapatites
the inorganic compunds of the matirix of hyaline cartilage
collagen fibers
the organic compounds of the matrix of hyaline cartilage
Coronal
sutures that join the frontal and parietal bones
Sagittal
sutures in the midline which join the 2 parietal bones
Squamosal
sutures that join the temporal bone to the parietal and sphenoid bones
Lambdoidal
sutures that joins the occipital bones
Wormian bones
small bones which lie in the sutures in between cranial bones
Fontanels
soft spots on babys skulls
kyphosis
hunchback. exaggerated concave curve of the thoracic region
lordosis
swayback. exaggerated convex curve of the lumbar region
