Joints, Ligaments, and Bone Anatomy: A Comprehensive Review
Joint Types
Joint Types:
- Synarthrosis: Exhibits minimal mobility due to dense fibrous tissue. Example: skull sutures.
- Amphiarthrosis: Allows limited movement and elasticity due to a higher fiber content. Movement depends on the fiber arrangement. Example: intervertebral discs.
- Diarthro-Amphiarthrosis: Permits slight mobility and fixation. Example: sacroiliac joint (sacrum and innominate).
- Diarthrosis: Highly mobile joints with liquefied tissue and a fibrous joint capsule. Example: knee joint, containing

R. jurásico
This landform can form in young mountain ranges. It consists of folds alternating between anticlines and synclines. Anticlines in the water create erosion valleys perpendicular to the summit (cluses) and parallel valleys (combos). Once erosion occurs, it empties fast, and former synclinal valleys are lifted (syncline hook). The erosion of the anticline valley exposes the anticline, and the cycle begins again.
R. apalachense
This landform forms covering a mountainous area that has been
