Study Notes
Structural Classifications and Actions of Joints
-
Sternoclavicular Joint
- Classified as synovial and saddle.
- Articulating bones include clavicular notch, sternal end of the clavicle, and first costal cartilage.
- Actions encompass elevation, depression, and circumduction.
- Functionally categorized as diarthrosis.
-
Acrominoclavicular Joint
- Structural classification is synovial and plane.
- Main action involves gliding of the scapula on the clavicle.
-
Humeroulnar Joint
- Classified as synovial and hinge.
- Primary actions are extension and flexion of the forearm.
-
Distal Radioulnar Joint
- Identified as synovial and pivot.
- Action involves the rotation of the radius with respect to the ulna.
-
Radiocarpal Joint
- Structural classification is synovial and condylar.
- Articulating bones are the distal end of the radius, lunate, scaphoid, and triquetrum.
-
Intercarpal Joint
- Classified as synovial and plane.
-
1st Carpometacarpal Joint (Thumb)
- Structure classified as synovial and saddle.
- Articulating bones comprise the 1st metacarpal and trapezium.
- Versatile actions include adduction, abduction, circumduction, extension, flexion, and opposition.
-
2nd-5th Carpometacarpal Joints
- Actions mainly involve gliding.
-
Metacarpophalangeal Joints
- 1st Joint (Thumb) classified as synovial and hinge.
- 2nd-5th Joints classified as synovial and condylar; actions encompass abduction, adduction, flexion, extension, and circumduction.
-
Interphalangeal Joints
- Both proximal and distal joints are classified as synovial and hinge.
Other Notable Joints
-
Epiphyseal Plate
- Classified as cartilaginous and synchondrosis; functionally, it is a synarthrosis.
-
Atlanto-Occipital Joint
- Classified as synovial and condylar; allows for extension/flexion of the head and slight lateral flexion.
-
Atlanto-Axial Joint
- Identified as synovial and pivot; facilitated head rotation.
-
Intervertebral Joints
- Joints between articular processes are synovial and plane.
- Joints between vertebral bodies are cartilaginous and symphysis, functionally classified as amphiarthrosis.
-
Vertebrocostal Joint
- Classified as synovial and plane, involved in slight gliding motions.
-
Lumbosacral Joint
- Joint between the body classified as cartilaginous and symphysis (amphiarthrosis).
- Facets classified as synovial and plane (diarthrosis).
-
Costochondral Joint
- Classified as cartilaginous and synchondrosis; consists of the sternal end of ribs and costal cartilage, functionally a synarthrosis.
Sternocostal Joints
- 1st Joint classified as cartilaginous and synchondrosis.
- 2nd-7th Joints categorized as synovial; serve as important articulations in the thoracic cage.
These classifications and joints play crucial roles in the mobility and stability of the axial skeleton and upper limb.
