joints - ✔✔✔any point where 2 points meet, whether or not the bone are moveable at the interface
anthrology - ✔✔✔study of joints
kinesiology - ✔✔✔study of musculoskeletal movement
joint name classification - ✔✔✔typically derived form the names of the bones involved
ex: glenohumeral joint
or by freedom of they movement
also clarified by the way adjacent bones joined
diarthrosis, ampiarthorsis, and synarthorsis - ✔✔✔diarthrosis: freely moveable (shoulder, knee, hip,
elbow)
amphiarthorsis: slightly moveable
synarthrosis: little or no movement
4 types of joints - ✔✔✔bony, fibrous, cartilaginous, synovial joint
bony joint (synostosis) - ✔✔✔2 bones, one separate, fused by osseous tissue
*synarthrosis or syarthrotic
ossification occurs with age, frontal and mandibular bones in infants
can occur in either fibrous or cartilaginous joints
3 kinds of fibrous joints - ✔✔✔sutures: synarthroses
gomphoses: synarthroses
syndemoses:synarthroses
, 3 types of suture - ✔✔✔serrate: interlocking wavy lines-coronal, saggital, interlocking wavy lines
lap(squamous)-overlapping beloved edges- temporal and parietal bones
plane(butt)-straight, non overlapping edges, maxilla
interosseous membrane - ✔✔✔2 bones are bound by longer collagenous fibers than in suture or
gomphosis
gompho - ✔✔✔nail or bolt
cartilaginous joints - ✔✔✔2 bones are linked by cartilage
2 types of cartilagenous joints - ✔✔✔synchondroses- amphiarthroses
symphyses-amphiarthroses
synchondroses - ✔✔✔bones are bound by hyaline cartilage
temporary joint in the epiphyseal plate in children, binds epiphysis and diaphysis
first rib attachment to sternum, other costal cartilages are joined to sternum by synovial joints
symphysis - ✔✔✔"growing together"
2 bones joined by fibrocartilage
pubic symphysis- right and left pubic joined by interpubic
bodies of vertebrae and intervertebral disc
synovial joint - ✔✔✔joint in which 2 bones are separated by a space called a joint cavity
diarthrosis- freely moveable
most familiar type of joint, freely moveable, most structurally complex type of joint, most likely to
develop painful dysfunction
