The Skeletal Sytem
| Question | Answer |
|---|---|
| Functions of the skeleton | -provides a framework -protects -contains red bone marrow -stores calcium |
| Bone tissues | -compact bone -spongy bone -osteon |
| Bone tissue that has haversian systems | Compact bone |
| Bone tissue that has NO haversian systems | Spongy bone |
| haversian system is | Osteon |
| Structural unit of compact bone | Haversion system |
| bone cells are called | osteocytes |
| what of the bone is made up of calcium salts and collagen | Matrix |
| what makes a long bone | a diaphysis and two epiphyses |
| what bones were first made of fibrous connective tissue | Cranial and facial bones |
| replacement by bone matric radiates from a center of ossification in each bone | fibrous connective tissue |
| Bone matrix is produced by cells called | osteoblasts |
| this process is not completed at birth; a baby has areas of fibrous connective tissue remaining between the bones of the skull | Fontanels |
| large cells that secretes acid and enzymes to dissolve and digest a microscopic bit of bone matrix, then absorbs the minerals and amino acids | Osteoclasts ( "destroying" cell) |
| what bones first center of ossification is in the diaphysis? | The Long Bones |
| All other bones are first made of? | Cartilage |
| what deposits matrix material and collagen? | Clusters of osteoblasts (called centers for ossification) |
| genetic potential | Heredity |
| What absorbs calcium in the small intestine | Vitamin D |
| what is needed for bone matrix production? | Vitamins A and C |
| what becomes part of bone matrix? | Calcium, Phosphorus, and protein |
| Bone growth and maintenance | Growth hormone, thyroxine, insulin parathyroid hormone, and calcitonin |
| Cessation of bone growth | Estrogen or testosterone (epiphyseal discs) |
| the skeleton contains how many bones? | 206 connected by ligaments |
| what is the Axial Skeleton? | the skull, vertebrae, and rib cage |
| what is the Appendicular skeleton? | the bones of the arms and legs and the shoulder and pelvic girdles |
| what are the joints called in the skull? | sutures, they are immovable |
| where are Paranasal sinuses? | in the frontal, maxillary, sphenoid, and ethmoid bones |
| what are the 3 auditory bones? | Malleus, incus, and stapes |
| where are the Cervical vertebrae located and how many are there? | Located in the neck, there are 7 |
| what are Thoracic vertebrae and how many are there? | Forms joints with the ribs on the posterior side of the trunk, there are 12 |
| where are the lumbar vertebrae located and how many are there? | they are the largest and strongest bones of the spine, are found in the small of the back. There are 5 |
| what are the Sacral Vertebrae, how many are there? | permits the articulation of the two hip bones, 5 sacral fused into 1 sacrum |
| what is the coccygeal vertebrae, how many are there? | remnant of the tail vertebrae, there are 4 to 5 small coccygeal vertebrae fused into 1 coccyx |
