joints structure and function
| Question | Answer |
|---|---|
| examples of symphysis (stucture is cartilage) | intervertebral disc and symphysis pubis |
| function of hyaline cartilage | cartilage designed for compression |
| define synchondrosis | bones that are joined by hyaline cartilage only |
| example of synchondrosis | epiphyseal plates |
| funtions of articular cartliage | reduce friction |
| hyaline cartilage contains no | nerves or blood vessels |
| bursae | prevents bones from bumping |
| examples of a pivot joint are | prox radius/ulna |
| Diarthroses function | freely movable (synovial joints) |
| Amphiarthroses function | slight movement (intervertebral discs) |
| Synarththoses function | no movement (sutures, teeth) |
| Fibrous joints (name 3 ssg) | sutures,syndesmoses,gomphsis |
| Plane joints allow | short gliding movement |
| Ball and socket joints allow | multiaxial movement |
| Example of saddle joint | the carpometacarpal (meat) joint of the thumb. |
| Saddle joints allow | side to side and back & forth |
| Example of condyloid joints | knuckles |
| Condyloid joints allow | side to side, back & forth |
| Example of pivot joint | axis/atlis C1-C2 |
| Pivot joints allow | lateral rotation |
| Examples of plane joints include | intertarsal |
| Examples of hinge joints are the: | elbow knee |
| Hinge joints allow | angular movement |
| the cartilagenous structure of the Symphysis joint is | intervertebral dics |
| the cartilagenous structure of the Synchondroses joint is | epiphyseal plates |
| the fibrous structure of the sydesmoses joint is | distal tibia/fibia |
| name 6 shapes of synovial joints | pivot,ball-n-socket,hindge, condyloid,saddle,plane |
| 3 factors of tendon sheaths | muscle tone, ligaments, fit of articular surface |
| What is Arthrology | study of joints |
| joints are classified by | structure and function |
| articulation means | where parts of skeleton meet |
| Define metabolism | the rate at which oxygen converts nutrients to energy |
| fibrous joints | sutures, gomphosis, and syndesmosis |
| sutures, syndesmoses, gomphosis | |
| sutures | bone edges interlock or overlap each other and are connected by a ligament or membrane |
| gomphosis | bones fit together like peg in a hole is the tooth |
| syndesmoses | bones are connected by a ligament or membrane that allows some movement. examples are radius and ulna, tibia and fibula |
| Synarthroses has two categoies | fibrous and cartilaginous joints |
| 2 types of cartilagious joints | symphysis and syndhondrosis |
| examples of symphysis (stucture is cartilage) | intervertebral disc and symphysis pubis |
| function of hyaline cartilage | cartilage designed for compression |
| synchondrosis | bones that are joined by hyaline cartilage only |
| components of synovial joints are | articular catilage, joint capsule, synovial fluid, ligaments and burae sacs |
| articular cartilage is | smooth layer on the surface of the bone |
| examples of synchondrosis | between the sternam and the 1st rib. |
| 3 function classification of joints are | synarthroses,amphiarthroses,diarthroses |
| name structure connected by ligaments (varies)ex: distal fibia/tibia | sydesmoses |
| all these joints are diarthroses | synovial joints |
| components of synovial joints are | articular catilage, joint capsule, synovial fluid, ligaments and burae sacs |
| funtions of articular cartliage | thin smooth layer on the surface of the bones |
| hyaline cartilage contains no | nerves or blood vessels |
| bursae | sac of synovial fluid used to reduce friction between moving tissues |
| Diarthroses function | freely movable (synovial joints) |
| Amphiarthroses function | slightly movable (ribs) |
| Synarththoses function | immovable joints ( skull) |
| Fibrous joints (name 3 ssg) | Sutures, sydesmoses,gomphoses |
| Plane joints allow | gliding or sliding |
| Ball and socket joints allow | flexion, extension, abduction, adduction,circumduction and rotation |
| Example of saddle joint | the carpometacarpal (meat) joint of the thumb. |
| Saddle joints allow | flexion, extension, abduction, adduction and circumduction. |
| Example of condyloid joints | The wrist & joints of the fingers and toes. |
| Condyloid joints allow | flexion, extension, abduction, adduction and circumduction |
| Example of pivot joint | Atlas/axis c1 & c2 |
| Pivot joints allow | rotation on long axis (prox radious) round end fit into ring |
| Examples of plane joints include | intertarsal (short gliding movement) |
| Examples of hinge joints are the: | elbow knee |
| Hinge joints allow | flexion and extension (cylindical end fits into trough shape of other) |
| the structure of the Symphysis joint is | intervertebral dics |
| the structure of the Synchondroses joint is | epiphyseal plates |
| the structure of the sydesmoses joint is | distal tibia/fibia |
| name 6 shapes of synovial joints | pivot,ball-n-socket,hindge, condyloid,saddle,plane |
| 2 factores of tendon sheaths | muscle tone, ligaments, fit of articular surface |
| What is Arthrology | study of joints |
| joints are classified by | structure and function |
| articulation means | where parts of skeleton meet |
| Define metabolism | the rate at which oxygen converts nutrients to energy |
