The sutures of the skull have several important roles. In development they are straight edged and lie on top of a network of soft cartilage and connective tissue to allow the head of the newborn to deform in order to fit through the narrow birth canal.
In adult life the main function of sutures is to distribute impact force evenly around the skull. The collagen present in the interfacial layer coupled with the jagged interlocking distribute impact force evenly across the entire length of the sutures and connecting bone. They are around 5 times stronger under impact than pure bone and as the collagen content goes up with increased interdigitation they can be stronger.
Under slow compression only extremely interdigitated suture can match the strength of pure cranial bone.

What else can I help you with?
What is the following describes the joints in the skull?
The joints in the skull are called sutures, which are fibrous joints that connect the bones of the skull. These joints allow for some flexibility during childbirth and skull growth in infancy, but become more rigid as we age to help protect the brain.
What are the types of fixed joint?
The types of fixed joints are suture joints, gomphosis joints, and synostosis joints. Suture joints are found in the skull, gomphosis joints are where teeth articulate with the jawbone, and synostosis joints are where bones have fused together, such as in the skull bones of infants.
Are skull joints called cartilaginous joints?
No, skull joints are not called cartilaginous joints. Skull joints are typically classified as fibrous joints, specifically sutures, because they are connected by dense fibrous connective tissue. Cartilaginous joints are joints where the bones are held together by cartilage, like the joints between vertebrae in the spine or the pubic symphysis.
What type of joints hold together the bones of the skull and sternum?
The joints that hold together the bones of the skull are called sutures, while the joints that hold together the bones of the sternum are called cartilaginous joints.
What type of joint is found at the shoulder and between the skull plates?
The shoulder joint is a ball and socket joint, allowing a wide range of motion. The joints between the skull plates are fibrous joints known as sutures, which are immovable joints that provide strength and support to the skull.
What are the kind of joints of skull bone?
Fixed joints are formed by the skull bones.
What sort of joint does the skull have?
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.

Can you have gout in joints in skull?
No
Is the skull movable?
No i do not think so but there are joints in the skull called suture joints just like little cracks
What joint does not bend?
Suture joints are practically immovable joints. You can find them in case of skull. They are there in case of skull, probably to allow the growth of individual bone, in order to increase the size of skull. With out joints, it would be very difficult to increase the size of the skull.
What part of the skeleton with immovable joints?
The part of the skeleton with immovable joints is the skull. The joints between the bones in the skull (sutures) are fibrous joints that do not allow for movement, providing protection and support for the brain.
What type of joints hold together the bones of the skull and sternum?
The joints that hold together the bones of the skull are called sutures, while the joints that hold together the bones of the sternum are called cartilaginous joints.
What type of joint is found at the shoulder and between the skull plates?
The shoulder joint is a ball and socket joint, allowing a wide range of motion. The joints between the skull plates are fibrous joints known as sutures, which are immovable joints that provide strength and support to the skull.
What joints are in the head?
The head contains joints such as the temporomandibular joint (TMJ), which connects the jawbone to the skull, allowing for movements like chewing and speaking. Additionally, the joints between the skull bones, called sutures, are immovable joints that help to protect the brain and maintain the structure of the skull.
