1.
appositional growth: increase in bone thickness/diameter balancing act between osteo clast and osteo blast
2.
bone blood cell formation function: hematopoiesis - occur within marrow cavities of certain bones
3.
bone characteristics: only connective tissue with solid matrix - bone cells like cat eyes suspended in yellow solid matrix
4.
bone development: osteogenesis
5.
bone function: support, protection, movement, storage, blood cell formation
6.
bone parts: epiphysis, daphysis, epiphysial plate, periosteum, endosteum, metaphysis
7.
bone support function: provides a hard framework that supports and anchors all soft orgns of the body
8.
chemical component of bones: organic and inorganic
9.
diaphysis: shaft
10.
endochondral ossification: bone forms from hyaline cartilage resulting to cartilage bones - long bones
11.
endosteum: inner layer
12.
epephysial plate/line: separates end and shaft
13.
epiphysis: ends
14.
example of sesamiod bones: patella, sides of metatarsals, in flexor tendons that pass posteriorly into the foot on either side of the ankle, flexor tendon of thumb near the MCP, IP, near MCP joint of index and little fingers
15.
examples of flat bones: scapula, ilium, cranial, ribs, sternum, clavical
16.
examples of irregular bones: vertebrae, auditory ossicles, mandible, hyoid, facial bones (sphenoid ethnoid), sacrum and coccyx
17.
examples of short bones: carpals and tarsals
18.
female fusion of bone age: bones fuse by age 18
19.
flat bone function: thick for attachment curved rather than flat
20.
flat bones: broad surface
21.
iliac crest is last bone to fuse: which is last bone to fuse
22.
inorganic components of bones: hydroxyapatities, calcium, phosphorous, potassium, magnesium, sodium, sulfur, copper
23.
intramembraneous ossification: bone forms from a fibrous tissue or membrane resulting in a membrane of bone, most of these are flat bones
24.
irregular bones: variety or mixed shapes
25.
logitudinal growth: increase in length of bone achieved by continuous cell division of underlying cartilage cells stacked one on top of the other this ends with the fusion of the epiphysis and diaphysis
26.
long bone function: strength and support (bones that make up extremities)
27.
long bones: length greater than width. largest bones,
28.
male fusion of bone age: bones fuse by age 21
29.
metaphysis: separates epipysial plate from diaphysis
30.
movement bone function: lever systems by virtue of being attached by muscle
31.
organic components of bones: osteo cyte, osteo blasts, osteoclasts, osteoids(osteons)
32.
osteoblasts: young bone cells
33.
osteoclasts: destroy excess bone
34.
osteocyte: old bone cells
35.
osteoids/osteons: organic part of matrix
36.
osteology: study of bones
37.
periosteum: outer layer
38.
protection bone function: skull protects brain, ribs/organs, vertebrae/spinal column, pelvis/organs
39.
sesamoid bone function: serve as an additional surface for muscle attachment for increase in leverage of particular joint
40.
sesamoid bones: extra bones that develop in connective tissue at points of stress
41.
short bone function: lots of articular surfaces and support
42.
short bones: equal dimenisons (square)
43.
storage bone function: fat, minerals (released as ions)- calcium, phosphorous, potassium, sodium, magnesium, sulfur, copper
44.
types of bones: long, short, flat, irregular, sesamoid, wormian
45.
wolff's law: structure of a bone depends on function of that particular bone - principle of complementary function
46.
wormian bone: found along suture lines in the skull
