Synchondrosis vs. Symphysis

Synchondrosisnoun

(skeleton) A form of only slightly-moveable articulation between bones joined by hyaline cartilage, as in the spinal vertebrae.

Synchondrosisnoun

An immovable articulation in which the union is formed by cartilage.

Synchondrosis

A synchondrosis (or primary cartilaginous joint) is a type of cartilaginous joint where hyaline cartilage completely joins together two bones. Synchondroses are different than symphyses (secondary cartilaginous joints) which are formed of fibrocartilage.

Symphysisnoun

(skeleton) The process of two originally separate bones growing together as the subject matures, as with the pubic bones or lower jawbones in humans.

Symphysisnoun

(skeleton) A place where two bones are closely joined in the median plane of the body, either forming an immovable joint (as between the pubic bones in the center of the pelvis) or completely fused (as at the midline of the lower jaw).

Symphysisnoun

(medicine) A line, discernable on an X-ray, showing such fusion.

Symphysisnoun

(skeleton) The cartilaginous material that adjoins and facilitates the junction of such bones, without a synovial membrane.

Symphysisnoun

An articulation formed by intervening cartilage; as, the pubic symphysis.

Symphysisnoun

an abnormal adhesion of two or more structures

Symphysisnoun

a growing together of parts or structures

Symphysis

A symphysis is a fibrocartilaginous fusion between two bones. It is a type of cartilaginous joint, specifically a secondary cartilaginous joint.
