The cranial bones are fused together at immovable joints known as sutures. The skull contains 22 bones of which 21 are fused together at these joints. The only skull bone that is capable of movement is the jaw bone.
The cranial bones e.g. parietal, frontal, temporal and occipital. They are fused together by sutures which do not allow movement and are known as fixed or immovable joints
Fibrous Joints are also known as immovable joints. An example of these are Cranial Joints found in the skull.
A fibrous joint, also known as a synarthrosis, is essentially immovable. These joints are held together by fibrous connective tissue, such as sutures in the skull, and allow for very limited to no movement.
Immovable joints, also known as fixed or fibrous joints, are located in the skull where the bones are tightly joined together by fibrous connective tissue. These joints provide stability and protection for the brain.
Immovable joints, also known as synarthroses, cannot move. These joints are characterized by a lack of joint cavity and dense connective tissue binding the bones together. The most common examples of immovable joints are the sutures in the skull, which allow for the growth of the skull during childhood but fuse and become immobile in adulthood.
In babies the skull joint is the fontanel (fontanelle) which helps in birth due to its flexibility but in the adult the skull joint is a fixed joint or a synarthrotic joint (immovable) called a suture.
The ziz-zag lines are known as sutures and form fixed, immoveable joints over the skull.
Immovable joints, also known as fibrous joints, are held together by connective tissue like cartilage or dense fibrous tissue. These joints allow for very little to no movement and provide stability and strength to the skeleton. Examples include the skull sutures and teeth sockets.
Muscles that attach to immovable joints are commonly known as fixed muscles. These muscles provide stability and support to the joint without producing significant movement. Examples include the muscles around the skull and sternum.
The joints which allow the least amount of movement are Fibrous Joints - also known as immovable joints. These joints are held firmly together by strong connective tissue and allow no or very little movement. Examples are the joints between the bones in the skull and the teeth.
The cranial sutures are fibrous joints, also known as synarthroses.
