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.
The xiphisternal joint (or xiphisternal symphysis) is a location near the bottom of the sternum, where the body of the sternum and the xiphoid process meet. It is structurally classified as a synchondrosis, and functionally classified as a synarthrosis. [citation needed] The joint usually ossifies by the fourth decade of life, [1] forming a ...
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).
Abduction is an anatomical term of motion referring to a movement which draws a limb out to the side, away from the median sagittal plane of the body. It is thus opposed to adduction . Upper limb
Joints are classified both structurally and functionally. [4] Joints play a vital role in the human body, contributing to movement, stability, and overall function. They are essential for mobility and flexibility, connecting bones and facilitating a wide range of motions, from simple bending and stretching to complex actions like running and ...
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.
In anatomy, a joint capsule or articular capsule is an envelope surrounding a synovial joint. [1] Each joint capsule has two parts: an outer fibrous layer or membrane ...
