|
|
bones are...
|
organs made of living tissue, fairly rigid structures
|
|
|
bone tissue cotains....
|
bone cells, blood vessels, and other minerals besides calcium, connective tissues and marrow.
|
|
|
Marrow
|
the source of red blood cell production
|
|
|
5 functions of bones
|
support, movement, protection, mineral storage, formation of blood cells
|
|
|
hemopoiesis
|
formation of blood cells
|
|
|
articular or hyaline cartilage
|
covers the broad ends of liong bones and provides a protective cushion against impact
|
|
|
Diaphysis
|
the long hollow portion of the long bone.
|
|
|
Endosteum
|
The membrane lining the hollow cavity of a long bone and containing bone cells called osteoblasts that are responsible for depositing calcium in the bones.
|
|
|
Epiphysis
|
The wide part at each end of a long bone. made of tissue softer than the diaphysis, and provide places for muscles to attach. In immature bones epiphysial cartilage lies between the diaphysis and the epiphysis
|
|
|
Medullary cavity
|
The hollow shaft inside the long bone. It contains the marrow.
|
|
|
Periosteum
|
A tissue covering the outside of the long bone, except at the ends. This tissue contains nerves and blood vessels, and also osteoblasts.

Crest
|
A large ridge on a bone where muscles can attach.
|

Epicondyle

A further prominent area on a condyle for muscle attachment.
|
|
|
Facet
|
A flat, smooth area that forms part of a joint with another bone.
|
|
|
Fissure
|
A thin opening like a crack, but naturally occurring as part of the bone's anatomy making a place for blood vessels or nerves.
|
|
|
Foramen
|
A hole in the bone where blood vessels, nerves or connective tissues pass though.
|
|
|
Fossa

The wine-colored portion on the ends of bones, usually serving as part of a joint.
|
|
|
Line
|
A small ridge on the bone where muscles attach.
|
|
|
Malleolus
|
A projection sticking out to either side of the end of a bone, on the end that is furthest from the body where muscles attach.
|
|
|
Meatus
|
A hollow tube-like opening passing through the bone where blood vessels or nerves can pass through.
|
|
|
Process
|
A section of the bone that sticks out prominently so that muscles can attach.

Part of an irregular bone that extends like an arm.
|
|
|
Sinus
|
A hollow cavity inside a bone.
|
|

|
Long bones
|
The tubular bones consisting of a shaft-like portion and broader ends. These are found in the upper and lower arms, the thigh and lower leg and also in the fingers and toes.
