Long bones
Bones of the limbs and hands/feet (<b>NOT</b> wrists and ankles)
Short bones
Carpal and tarsal and patella.
Irregular bones
Vertebrae, middle-ear bones
Medullary Cavity
Also known as marrow cavity, contains bone marrow.
Diaphysis
Shaft of bone. (Leverage)
Epiphysis
Enlarged head of bone. (strength joint/provide muscle attachments) Proximal and Distal.
Articular Cartilage
Type of hyaline cartilage found at the articulation (joint) of bones.
In between Epiphysis and Diaphysis.
Metaphysis
Periosteum
Sheath of outer fibrous collagen and inner osteogenic layer of bone forming cells.
Sharpey's fibers
Anchors the periosteum to the bone matrix.
Thin layer of reticular CT lining internal marrow cavity. Also covers honeycomb surfaces of spongy bones and has many osteoclasts.
Endosteum
Epiphyseal plate
Hyaline cartilage separating the marrow spaces in children. Where the bones grow in length. Is just an /epiphyseal line/ in adults.
Bone Marrow
soft tissue that occupies marrow cavity of long bones, spaces amid trabeculae of spongy bone, and larger central canals.
Red Bone Marrow
Produces blood cells.
Yellow Bone Marrow
Red marrow of bones in limbs turns into this in adults.
Sesamoid
Any bone that is embedded in a muscle or tendon.
Hydroxyapatite
Mineral that makes up 2/3 of compact bone.
Canaliculi
Very small canals that connect the lacunae to the Haversian canals.
