Joints:
Structural classification: 1. 2. 3. |
Fibrous- immovalbe or slightly movable
cartilagenous- " " synovial- freely movable |
1.F
2.C 3.S |
|
|
Fibrous Joints:
|
connected by fibrous connective tissue with no joint cavity
|
|
|
|
Sutures of fibrous joints:
I.Found where? II.Connects what? III.long or short? IV.what is synostoses? |
I.in joints of skull only till middle age
II. zig zag bones edges by connective tissue fibers that are continuous w/ periosteum. III. Short IV. completely immovable bony junctions-not joints anymore. |
|
|
|
Syndesmoses
A. connected by... B. what does length indicate? C. examples: |
A. bands of connective tissue (ligaments)
B. dictates if any movement allowed. C. Tibiofibular (short, barely moveable), Interosseous membrane between radius and ulna(broad ligament with long fibers, allows pronation) |
|
|
|
Gomphoses
what are they? (this is easy!) |
Teeth!!! nail in soket with short fiberous connections (periodontal ligament)
|
|
|
|
gliding
|
one flat surface slips over another.
ex: intercarpal and intertarsal joints, intervertebral joints. |
|
|
|
Angular movements
|
changing angle of one bone relative to another in one plane
|
|
|
|
Flexion/Extension
Hyper means? |
decrease/increase angle in sagittal plane
hyper means beyond natural position |
|
|
|
dorsiflexion/ plantar flexion
|
for feet only
|
|
|
|
abduction/ adduction
|
away from/ toward the midline in frontal plane
|
|
|
|
inversion/eversion
|
for feet only- sole turns medially/laterally at ankle
|
|
|
|
circumduction
|
hips and shoulders primarily
makes cone w/ a limb (distal end draws circle. ) |
|
|
|
Rotation
|
turning a bone on its long axis.
ex: atlas on axis, hips, shoulders |
|
|
|
supination/pronation
|
uncrossing/crossing radius from over ulna/
|
|
|
|
protraction/ retraction
|
mandible only- anterior & posterior movement in horizontal plane
|
|
|
|
elevation/ depression
|
superior and inferior movements in sagittal plane
ex: shrugging shoulders and chewing |
|
|
|
opposition
|
only carpometacarpal joint of thumb (due to saddle joint) allows thumb to contact each finger tip
|
|
|
|
Plane joints
|
flat articular surfaces that glide on one another only
ex: intervertebrals, intercarpals, intertarsals |
|
|
|
hinge joints
|
a cylinder-shaped process fits in a wrench-shaped holder; allows flexion/extension only
ex: elbow, interphalangeal joints |
|
|
|
pivot joints
|
rounded head of a bone fits in a sleeve of bone and/or ligaments that allows it to rotate only
ex: atlas on dens, proximal radioulnar joint. |
