amphiarthroosit

Amphiarthroosis refers to a type of cartilaginous joint in anatomy. These joints are characterized by a limited amount of movement, often described as slightly movable or amphiarthrotic. The bones in an amphiarthrosis are united by fibrocartilage or a combination of hyaline cartilage and fibrocartilage. This type of articulation allows for a degree of flexion, extension, or rotation, but not free movement as seen in diarthroses (synovial joints).

Examples of amphiarthrooses include the symphysis pubis, which connects the two pubic bones of the pelvis, and the intervertebral discs, which are found between the vertebrae of the spine. The flexibility provided by these joints is crucial for functions such as childbirth in the case of the symphysis pubis and the absorption of shock and maintenance of spinal posture for the intervertebral discs. While movement is restricted, it is sufficient for their intended biological roles. The degree of movement can vary depending on the specific amphiarthroosis.
