Long Bone
A type of bone that is longer than it is wide. Examples include the femur, humerus, and phalanges.
Short Bone
a bone that is roughly cube shaped (eg wrist and ankle bones)
Irregular Bone
Bones with complicated shapes (e.x., vertebrae and hip bones)
Flat Bone
A type of bone with a thin flattened shape. Examples include the scapula, ribs, and pelvic bones.
Compact Bone
Hard, dense bone tissue that is beneath the outer membrane of a bone
Spongy Bone
Layer of Bone tissue having many small spaces and found just inside the layer of compact bone
Axial Skeleton
the part of the skeleton that includes the skull and spinal column and sternum and ribs
Appendicular Skeleton
the part of the skeleton that includes the pectoral girdle and the pelvic girdle and the upper and lower limbs
Diaphysis
shaft of a long bone
Epiphyseal Plate
The cartilaginous region between the epiphysis and the diaphysis of a growing bone.
Epiphysis
the end of a long bone
Periosteum
a dense fibrous membrane covering the surface of bones (except at their extremities) and serving as an attachment for tendons and muscles
Articular Cartilage
The cartilage pad that covers the surface of a bone inside a joint cavity
Red Marrow
a mixture of mature and immature red blood cells, white blood cells, and the stem cells that produce them. Found in "spongy bone"
Yellow Marrow
made up of fat cells for long term storage. Found in the "Medullary Cavity"

Osteocytes
Mature bone cells.
Osteoblasts
Bone-forming cells. Responsible for osteogenesis.
Osteoclasts
Bone-destroying cells.
Lacunae
A small spaces between the lamellae. Each contains an osteocyte.
Lamellae
A layer of bone tissue/matrix
Haversian Canal
or Central Canal, contains one or more blood vessels. Runs parallel to the bone surface.
Volkmann Canals
Canals perpendicular to the surface of the bone. They carry blood to the deeper osteons and marrow cavity
Tuberosity
large rounded projection; may be roughened.
Crest
narrow ridge of bone; usually prominent
Trochanter
Very large, blunt, irregularly shaped process. (Only on the Femur)
Line
Narrow ridge of bone; less prominent then a crest
Tubercle
Small, rounded projection or process
Epicondyle
Raised area on or above a condyle
Spine
Sharp, slender, often pointed projection.
Process
Any bony prominence
Head
Bony expansion carried on a narrow neck
Facet
smooth, nearly flat articular surface
Condyle
rounded articular projection
Ramus
Armlike bar of bone
Meatus
Canal-like passageway
Sinus
Cavity in bone, filled with air and lined with mucus membrane
Fossa
shallow, basinlike depression in a bone, often serving as an articular surface.
Groove
furrow
Fissure
Narrow, slitlike opening
Foramen
Round or oval opening through bone.
