Bones Pt2

Origin is

the end of the muscle that is attached to a stationary part of bone.

insertion is the

The end of the muscle that is attached to a mobile section of bone

tendons..

attach muscles to bone

Ligaments..

attach bone to bone

epiphysis is the

two ends of long bone

diaphysis is the

shaft of long bone

epiphyseal plate is

a growth region of cartilage between epiphysis and diaphysis

epiphyseal line is

formed in the bone when growth has ended.

endosteum is the

membrane lining the medullary cavity

periosteum is the

membrane covering outer surface of the bone composed of connective tissue. Bone does not have nerves, but periosteum is full of nerves causing pain when bone breaks

medullary cavity is the

hollow area in the center of the bone where bone marrow is located, produces blood cells

Diploe is

spongy bone knowns as cancellous bone

Compact bone is

dense, hard layer of the bone

Long bone is

dumb bell shaped, wide expanded ends, narrow, cylindrical mid section. Long bones aid in movement carry weight of the body

flat bone is

flat in 2 dimensions, thing and curved, surrounded diploe by thin layer of compact bone, function is to protect vital organs (EX sternum)

short bone is

round or cubicle shape, bones reduce friction and concussion (EX carpels)

sesamoid bones ..

that form in tendons and aid in movement (EX patella)

what is irregular bone

bones of vertebral column

Pneumatic bone is

bones that contain spaces filled with air, which serve numerous functions

Joints are

point which two or more bone meet. Line with cartilage provides cushion//smooth movement

fibrous/immoveable are

bones in this joint do not move. May not overlap or interlock and held together by fibers

cartilaginous/slightly moveable allows

for some movement. Bones held together by ligaments and padded with cartilage

synovial/freely moving are the

largest group of joints in the body. Have wide range of motion
