Skeletal structures and their functions
Question | Answer |
---|---|
ossification | process of bone formation |
osteoclasts | Cells that break down old or damaged bone |
osteoblasts | Bone building cells |
periosteum | tough, fibrous tissue that forms the outermost covering of bone |
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. -Lighter and weaker than compact bone -Red bone marrow often located here |
medullary cavity | -central cavity located in the shaft of long bones -yellow bone marrow stored here |
endosteum | tissue that lines the medullary cavity |
red bone marrow | Hemopoietic tissue that manufactures red blood cells, hemoglobin, white blood cells, and thrombocytes. Located within the spongy bone. |
hemopoietic | pertaining to the formation of blood cells |
yellow bone marrow | fatty tissue found in the medullary cavity of most adult long bones |
cartilage | the smooth, rubbery, blue-white connective tissue that acts as a shock absorber BETWEEN BONES |
meniscus | the curved fibrous cartilage found in some joints, such as the knee and the temporomandibular joint of the jaw |
diaphysis | shaft of a long bone |
epiphyses | ends of long bone |
foramen | Round or oval opening through a bone |
process | a normal projection on the surface of a bone that most commonly serves as an attachment for a muscle or tendon |
chondr/o | cartilage |
arthr/o | articulation, joint |
flat bones | These bones are thin, flat, and curved. They form the ribs, breastbone, and skull. |
irregular bones | bones of the vertebrae and pelvis |
long bones | longer than they are wide, bones of the arms and legs, Humerous, Radius, Ulna, Femur, Fibula and Tibia |
short bones | Similar in length and width and appear somewhat cubicle in shape Ex. Carpals of hand, tarsals of feet |
