Exam 2 AP
| Question | Answer |
|---|---|
| osteocytes | mature bone cell |
| osteoblasts | builders |
| osteoplasts | made in bone marrow, old and damaged |
| red bone marrow | stationary, no matrix |
| yellow bone marrow | fat, doesn't make blood cells, lubricates our bones |
| bone marrow aspiration | used to diagnose blood disorders |
| intramembranous ossification | makes bone in the membrane, flat bones, direct method |
| endochondral ossification | makes model of cartilage first then hardens it, indirect method, limb bones |
| bones growing in length | ossify cartilage grows upward and downwards in size |
| bones grow in width | lay down more bone on the outside, bone layers |
| deposition | bone remodeling |
| resorption | destroying bone |
| calcitrol | activated vitamin d |
| calcitonin | thyroid hormone, stimulates osteoblasts |
| parathyroid hormone | destroys osteoclasts, maintains calcium levels |
| simple | no open wound |
| oblique | break runs are an angle or slant |
| comminuted | bone splinted into fragments |
| spiral | break coils around bone |
| pathologic | break is at site of bone disease |
| displaced | bony ends do not line up |
| transverse | break runs across bone |
| compound | wound in skin communicates with fracture |
| process | something that sticks out |
| meatus | canal or tunnel |
| condyle | round smooth joint surface |
| epicondyle | wide ends of long bones |
| sinus | cavity/space |
| foramen | hole that is open |
| alveolus | sac or socket |
| fossa | depression, cave in bone |
| tubercle | bump on bone, so we can attach other bones |
| trochanter | on femur only, bump on bone |
| fovea | pit on head of femur |
| head | top of bone |
| tuberosity | roughened bump on bone |
| sutures | cracks |
| coronal | crown, divides skull into front and back sides |
| squamousal | flat, near temple |
| lambdoidal | in back of skull, looks like an upside-down y |
| pterion | wing, looks like an H, near temples |
| anterior cranial fossa | front of brain, protects, has CN2 |
| middle cranial fossa | bottom of skull near chin, holds temporal lobe |
| posterior cranial fossa | back of head, holds cerebellum, spinal cord, and brain stem |
| temporal bone | where your temples are |
| sphemoid | bat shaped thing, in between temporal and frontal, protection |
| ethmoid | nose |
| fetal skull | bones haven't fused together |
| adult skull | bones have fused together |
| ear infections | more common in kids, they have an opening in their ear canal that lets in bacteria, adults have it fused together |
| OFC | chart of head size |
| sunken | dehydration |
| bulging | bubble in soft spot, increase pressure on skull |
| trabecula | in between flat compact bones, web like |
| Flat bones | sandwich- compact bones on the outside, trabecula and red bone marrow on the inside |
| long bones | yellow bone marrow, metaphysis, diaphysis, epiphysis, hyaline cartilage, compact bone, periosteum |
| metaphysis | growing part of a long bone, on the body prt of the epiphysis |
| diaphysis | center part of a long bone |
| epiphysis | ends of a long bone |
| hyaline cartilage | top/bottom of bone, how the bone connects to another bone |
| periosteum | membrane that covers the bone |
| compact bone | hard shell of the bone |
| craniostenosis | bones fuse prematurely in baby |
