Joints of the thoracic wall Flashcards
Intervertebral joint type
symphisis (secondary cartilaginous)
intervertebral joint articulation
adjacent vertebral bodies joined by intevertebral disc
intervertebral joint ligaments
anterior and posterior longitudinal
intervertebral joint movement
limited movement to small degrees of rotation
costovertebral joint type
- joints of head of rib
- costotransverse
synovial plane joint
costovertebral joint articulation
head of each rib with superior demi or costal facet of vertebral body of same # +
inferior demi or costal facet of vertebral body superior to it +
IV disc btwn
tubercle of rib with transverse with transverse process of vertebra of same #
costovertebral joint ligaments
radiate and intra-articular ligaments of head of rib
lateral and superior costotransverse
costovertebral joint articulation differences
heads of 1st, 11th + 12th ribs only articulate with vertebral body of same #
11th + 12th ribs dont articulate with transverse vertabrae of same #
costochondrial joint type
primary (hyaline) cartilaginous joint
costochondral articulation
lateral end of costal cartilage with sternal end of rib
costochondral ligaments
cartilage and bone bound by periostium
costochondral movements
no movement but costal cartilage provides flexibility
interchondral joint type
synovial plane joint
interchondral articulation
btwn cartilages of 7th and 8th, 8th and 7th and 8th and 9th
interchondral ligaments
interchondral ligaments
interchondral joint articulation differences
articulation btwn cartilages on 9th + 10th rib is fibrous
sternocostal joint type
1st: primary cartilaginous joint (synchondrosis)
2nd-7th: synovial plate joint
sternocostal joint articulation
articulation of 1st costal cartilage with manubrium
articulation of 2nd-7th with sternum
sternocostal joint ligaments
anterior and posterior radiate sternocostal + intra articular
sternocostal joint cavities
articular cavities absent, fibrocartilage covers articular surface
sternoclavicular joint type
saddle synovial joint
sternoclavicular joint articulation
sternal end of clavicle with manubrium and 1st costal cartilage
sternoclavicular joint ligament
anterior and posterior sternoclavicular, costoclavicular
sternoclavicular joint division
divided by articular disc
menubriosternal joint type
secondary cartilaginous joint (symphysis)
menubriosternal joint articulation
articulation btwn menubrium and body of sternum
menubriosternal + xiphisternal joint in age
fuse and become synostoses in age
xiphisternal joint type
primary cartilaginous joint (synchondroses)
xiphisternal joint articulation
articulation btwn xiphoid process + body of sternum
