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 |
