Skeletal System Review
| Question | Answer |
|---|---|
| Compact Bone | Osteocytes and layers of matrix are clustered around a central canal |
| Spongy Bone | Osteocytes and layers of the matrix are NOT clustered around a canal |
| Periosteum | Fibrous connective tissue surrounding the bone |
| Epiphysis | End of bone |
| Osteocytes | Transport nutrients and wastes to and from nearby cells. |
| Endochondral bones | Long bones |
| Intramembranous bones | Flat bones |
| Epiphyseal Plate | A band of cartilage at the ends of bones |
| Osteoblast | Deposit bony matrix |
| Osteoclast | Break down calcified matrix |
| Vitamin A | Necessary for osteoblast and osteoclast development |
| Vitamin C | Required for collagen synthesis required for bone matrix |
| Vitamin D | Aids in the proper absorption of calcium |
| Calcium | Stored in bones and provides matrix but mainly used in muscle contraction |
| Phosphate | Combines with calcium to form a salt which is stored in the bone called hydroxyapatie |
| GH (growth hormones) | Secreted by the pituitary gland to stimulate division of cartilage cells in the epiphyseal plate |
| Sex hormones | Turn on during puberty and cause long bones to grow and ossification of the growth plates. |
| Examples of flat bones | Cranium, rib cage |
| Examples of long bones | Phalanges |
| Examples of short bones | Carpals, tarsals |
| Examples of irregular bones | Vertebrae, facial bones |
| Example of sesamoid bone | Patella |
| List four functions of skeletal system | Protection, support, storing nutrients, creating red blood cells |
| All bones originate from this cartilage: | Hyaline cartilage |
| Frontal bones | Forehead and eyes |
| Parietal | Most of the top and side of skull |
| Occipital | Back and most of the base of the skull |
| Temporal | Lower sides of skull |
| Sphenoid | Mid skull |
| Ethnois | Forms part of nose |
| Mandible | Lower jaw |
| Maxilla | Upper jaw, parts of hard palate of mouth, orbits and nasal cavity |
| Zygomatic | Cheeks |
| Nasal | Bridge of nose |
| Lacrimal | Inner part of eye |
| Palatine | Hard palate of mouth |
| Vomer | Part of nasal septum |
