| Question | Answer |
|---|---|
| glen- | joint;socket |
| inter- | between |
| intra- | within |
| lamell- | thin plate |
| meat- | passage |
| odont- | tooth |
| poie- | make |
| acetabul- | vinegar;cup |
| ax | axis;skeleton` |
| -blast | bud |
| canal | channel |
| carp- | wrist |
| -clast | break |
| clav- | bar |
| condyl- | knob;kunckle |
| corac- | crow's beak |
| cribr- | sieve |
| crist- | crest |
| fov- | pit |
| bone deposition | action of osteoblast and calcitonin |
| bone resorbtion | action of osteoclast and parathyroid hormone |
| vitamin c (to bones) | nessary for collagen productionabnormal, intake of vitamin C results in slender and, fragile bones |
| vitamin a (to bones) | nessary for bone resorbtion/deposition during, development |
| 5 bone types | long, short, flat, irregular, sesamoid |
| physical stress (to bones) | stress produces more collagen deposition on, bone |
| sex hormone (to bones) | stimulates osteoblasts to produce bone tissue |
| thyroid hormone (to bones) | stimulates ossification of cartilage @, epiphyseal plate |
| growth hormone (to bones) | stimulates cartilage production @ epiphyseal, plate |
| vitamin d (to bones) | nessasary for Ca absorbtion w/o Ca bones are, softer. |
| Rickets | vitamin D deficiency in children, signs are, bowed legs, deformed head |
| hip pointer | injury to the anterior;superior iliac spine |
| lordosis | exaggerated Lumbar curvature |
| scoliosis | lateral curvature of spine |
| kyphosis | exaggerated thoracic curvature |
| cleft palate | prenatal incomplete closer of maxilla |
| sternal punture | removal of red marrow from within the, sternums spongy bone, very easy to reach, the iliac crest is also another place to, aquire red marrow from the body |
| club foot | a common condition developed prenatally, in, which the foot is moved out of it's normal, position. This is usually easy corrected, with special shoes or maybe some surgery. |
| 5 functions of the skeleton | support, protection, hemopoiesis, mineral, storage (Ca & P), attachment site for tendons. |
| articular cartilage | hyaline cartilage on the ends of bones that, serve to enhance the movement of joints and, perserve longevity of end of bone. |
| periosteum | covering of collagen around bone that, develops into bone during physical stresses.These stresses result in knobs that enhance muscular attachments. Vascular in nature. |
| medullary (marrow) cavity | inner hollow chamber of diaphysis, contains, larger vascular network, storage of fat,(yellow marrow), and site of hemopoiesis,(red, marrow) |
| sickle cell disease | condition where abnormal hemoglobin changed, shape of red blood cells, this obstructs, circulation. In red marrow where red blood, cells are production the blood vessels can, become blocked causing bone pain. |
| endosteum | contains bone forming cells and lines the, medullary cavity |
| epiphyseal plate | a plate of cartilage developed between the, epiphysis and diaphysis of bones. This, turns, to bone later in life and marks the, end of growth of the bones when it, dissapears, |
| 2 types of marrow and where they are found | red and yellow marrow, both are found in the, spongy bone of the skull, ribs, sternum, clavicles, vertebrae, and hip, bones. Yellow marrow replaces red during, aging but can revert back to red marrow if, the body needs greater hemopoiesis. |
| matrix and it's relationship to osseous tissue | extracelluar parts of bone histology that, contains collagen and inorgainc salts. |
| collagen and in matrix | collagen gives bones resilance and strength |
| inorganic salts in matrix | gives bones hardness and resistance to crushing |
| trabeculae | found in spongy bone is a irregular and very, porous matrix of bone to lessen weight of bone, |
