A synchondrosis (or primary cartilaginous joint) is a type of cartilaginous joint where hyaline cartilage completely joins together two bones. [1] Synchondroses are different from symphyses (secondary cartilaginous joints), which are formed of fibrocartilage , and from synostosis (ossified junctions), which is the fusion of two or more bones.
Secondary cartilaginous joints are known as "symphysis".These include fibrocartilaginous and hyaline joints, which usually occur at the midline. Some examples of secondary cartilaginous joints in human anatomy would be the manubriosternal joint (between the manubrium and the body of the sternum), intervertebral discs, and the pubic symphysis.
Various bones of the human skeletal system. The axial skeleton, comprising the spine, chest and head, contains 80 bones. The appendicular skeleton, comprising the arms and legs, including the shoulder and pelvic girdles, contains 126 bones, bringing the total for the entire skeleton to 206 bones.
Synchondrosis of these two bones forms the clivus. On axial planes, it sits just posterior to the sphenoid sinuses. It is medial to the foramen lacerum and proximal to the anastomosis of the internal carotid artery with the Circle of Willis. (The artery reaches the middle cranial fossa above the foramen lacerum).
Side view of the skull Human skull side sutures right. A suture is a type of fibrous joint that is only found in the skull (cranial suture). The bones are bound together by Sharpey's fibres. A tiny amount of movement is permitted at sutures, which contributes to the compliance and elasticity of the skull. These joints are synarthroses. [1]
The body of the hyoid bone is the central part of the hyoid bone. [clarification needed]At the front, the body is convex and directed forward and upward. It is crossed in its upper half by a well-marked transverse ridge with a slight downward convexity, and in many cases a vertical median ridge divides it into two lateral halves.
