front 1 The skeleton provides what functions? | back 1 produces blood cells, provides protection for organs, helps us breathe, acts a warehouse for mineral storage, and allows for movement |
front 2 Bone Types Long Bones | back 2 longer than they are wide and are found in your ARMS & LEGS |
front 3 Bones Types Short Bones | back 3 fairly equal in width and length, similar to a cube, mostly found in your WRISTS and ANKLES |
front 4 Bone Types Flat Bones | back 4 thinner bones that can be either flat or curved and are platelike in nature in the skulls, ribs, and breastbone(sternum) |
front 5 Bone Types Irregular Bones | back 5 like the parts of a jigsaw puzzle, odd, shaped bones needed to CONNECT to other bones Example: hip bones, and the vertebrae that make up your spine |
front 6 Bone is covered with what? And what is its main function | back 6 periosteum and its a tough fibrous connective tissue containing blood vessels that transport blood and nutrients into the bone to nurture the bone cells...It also contains lymph vessels, nerves, and cells that tear down and rebuild bone |
front 7 The periosteum acts as an | back 7 anchors point for ligaments and tendons |
front 8 Each Bone end is called a ? | back 8 epiphysis |
front 9 The region running between or running through the bone is called? | back 9 diaphysis, and it is hollow |
front 10 The hollow region is the diaphysis is called? | back 10 the medullary cavity, and it acts as a storage area for bone marrow |
front 11 There are two kinds of bone marrow, what are they | back 11 Yellow and red |
front 12 What does red bone marrow do? | back 12 makes a variety of blood cell types that include erythrocytes, white blood cells, and platelets |
front 13 What does yellow marrow do? | back 13 high fat content, when you need more red blood cells, some of this can revert to red bone marrow to help in red blood cell production |
front 14 Bone Tissue Compact | back 14 a dense, hard tissue normally found in the shafts of long bones and the outer layer of other bones, tightly packed which makes for dense and strong structure |
front 15 osteons | back 15 also known as haversian systems, the primary structural and functional units of compact bone cylindrical structures |
front 16 The area around the osteocytes is filled with | back 16 protein, fibers, calcium, and other minerals |
front 17 To ensure there is sufficient oxygen and nutrients for the bone cells osteons are connected with | back 17 perforating cells |
front 18 spongy bone | back 18 arranged in bars and plates called trabeculae |
front 19 Spongy bone is lined with | back 19 endosteum |
front 20 What are the purposes of spongy bone? | back 20 it helps makes the bones lighter in weight and it provides a space for red bone marrow |
front 21 Osteoclasts job is to | back 21 tear down bone material and help move calcium and phosphate into the blood extremely important for bone growth and repair |
front 22 Osteoblasts | back 22 builders, laying down brick to make new exterior walls |
