Bone Function

Bone Function Besides function main bone as compiler frame body, Still There is function- function bone Which other, between other as following. a) Giver form body. b) Protector organ body which vital. c) Restrainer/enforcer body. d) Place formation cell blood. e) Place keep mineral especially calcium and Phosphor. f) Place keep reserve fat in marrow yellow. g) Place attached to it muscle. Joint Cartilage (Joint) The bones in the body interlock with each other connection One The same other so that mem-form frame body. Connection between bones called also articulation . For can ber- motion, on connection between bones there is structure Which special. Structure special here it is Which called joints. Process formation The joint begins with swelling cartilage. So second end cartilage That covered network tie. Furthermore, second end cartilage That form cells bone And both of them shrouded by membrane joints Which called synovial . Membrane synovial Thisthe situation clay And can produce oil lubricant bone Which called oilsynovial. Picture 1. Joints And the parts. In the human body skeleton there are three patterns of connection between bones or joint, that is synarthrosis , amphiarthrosis , And diarthrosis . Following will explainedOne per One. a. Synarthrosis (Joints Dead) Synarthrosis, that is pattern connection between bones Which The same very No own gap joints. Connection between bones on pattern This, connected with tightly by network fiber, Because That No Can moved (joint dead). Pattern connection bone Which called synarthrosis shared become two type main, namely suture and synchondrosis . Suture is a synarthrosis relationship pattern connected with network tie fiber congested, for example on bone skull. Synchondrosis is synarthrosis Which connected by cartilage hyaline, for example connection between bone epiphysis And diaphysis on bone mature, connection bone Whichlike This No can moved. b. Amfiartrosis On pattern connection bone amphiarthrosis, joints connected by cartilage so that possible For A little happen movement. Pattern connection This shared become two, that is symphysis And syndesmosis . On symphysis, joints connected by cartilage fibers that are flat in shape. This relationship pattern can be found in joints intervertebral And symphysis pubis, whereas on syndesmosis, joints connected by network tie fiber And ligament. Syndesmosis for example on joints betweenbone calf And bone dry. Picture 2. Connection interbones, that is (a) synarthrosis, diarthrosis c. (b) amphiarthrosis, And (c) Diarthrosis (Joints Motion) Picture 3. A number of type joints on body man between other joints bullet, joints hinge,joints turn, And joints slide. 1) Joints Bullet On pattern connection This, second end bone No connected by network so that possible happen movement. Name other For pattern connection diarthrosis, that is connection synovial. Diarthrosis is connection between bones Which characterized by his freedom on moment moved And nature flexible. A number of characteristic special from pattern connection diarthrosis, that is: 1) surface the joints shrouded by membrane or capsule Which made of from network tie fibrous; 2) in part in capsule there is barrier. Barrier This is membrane network tie Which called also membrane synovial. Membrane This produce fluid lubricant Which called fluid synovial Which its function For reduce friction; 3) capsules its fibrosis there is which reinforced by ligaments and there is anyway which no, and at in capsule usually be found bearings fiber bone vulnerable Ball joints, namely joints that allow this to occur movement mechanism in all directions. Joints like this occur in joint Which formed by connection between bones bracelet shoulder And bone arm part on, Also there is on joint Which formed by connection between bone bracelet pelvis And bone thigh. Connection bone Which including to in pattern connection diarthrosis, that is joints bullet, joints hinge, joints turn, joints saddle, joints ovoid, And joints slide. Following will explained How mechanism every joint do movement. Joints turn is joint in where end bone Which One can around end bone Which other. Circumstances connection Which thereby possible movement rotation with One axis, like joint between bone cubit And lever or between bone atlas with bone skull. 2) Joints Hinge Joints hinge is joint Which formed by connection between bones Which only possible happen movement to One direction. Joint like This can found on joint Which formedby sections bone finger foot nor hand or joint Which formed by bones Which form elbow And kneel. 3) Joints Saddle or Interrupt Joints saddle is joint Which formed by connection between bones Which possible happen movement second direction. Joint like This there is on connection between bone palm hand And baseMother finger. 4) Joints Spin 5) Joints Ovoid On joint This his movements pivot two, that is motion to left And to right, proceed backwards, And to advance to behind. On joint ThisWrong One end his bones shaped oval, whereas bone other Which is his partner own curve ellipse For place entry bone Which shaped oval earlier. 6) Joints Glide Second end bone on joints slide rather flat so that possible movement shift And No own axis. Joints slide for example there is on joints between bone wrist hand, between the wrist bones foot, bone rare, And bone shoulder blades.
