BONES Flashcards
Osteoblasts
produce bony tissue
Osteoclasts
large cells that reabsorb or digest bony tissue
diaphysis
the shaft of a long bone
Epiphysis
each end of a long bone
Epiphyseal Line
An area of cartilage tissue that is constantly being replaced by new bone tissue (long bone)
Metaphysis
Flared portion of the long bone
Periosteum
strong, fibrous, vascular membrane that covers the surface of long bones
(except at the end of epiphyses)
articular cartilage
the ends of long bones and the surface of any bone that meets another bone to form a joint
Compact Bone
a layer of hard, dense bone that lies under the periosteum in all bones
Haversian Canals
a system of small canals containing blood vessels that bring oxygen and nutrients to the bone and remove waste products
Medullary Cavity
Cancellous Bone
a spongy, porous bone tissue that contains red bone marrow within its spaces
red bone marrow
immature and mature bloods in various stages if development
Hematopoieses
the production of all types of blood cells in the bone marrow
bone processes
enlarged areas that extend out from bones and serve as attachment for muscles, tendons, and ligaments
bone depressions
openings or hollow regions serving as connections between bones or passageways for blood vessels and nerves
Bone Head
rounded end of a bone
Condyle
rounded knuckle-like process, at the end of the bone
Epicondyle
small rounded process above the condyle
trochanters
large and small processes for tendon attachments on the femur
Tuberocity
round elevation where tendons and muscles attach on the humerus, calcareous, and pelvis
Fissure
Narrow groove or slit like opening
Foramen
Opening for blood vessels and nerves
Fossa
Shallow cavity in or on a bone
Sinus
Hollow cavity within bone
Sutures
The joints that join the cranial bones together
fontanelles
the soft spots or ‘gaps’ of unossified tissue in the skull at birth
Mental Foramen
Opening in the mandible that allows blood vessels and nerves to enter and leave
Coronal Suture
Connection across the skull between the two parietal bones and the frontal bone
Ethmoid Bone
Supports nasal cavity and eye sockets
Frontal bone
Forehead; part of eye sockets
Occipital bone
Back and base of skull
Parietal bones
Top and sides of skull
