A fused joint in the human skull, also known as a suture, refers to the immovable joints where the bones of the skull are tightly joined together. These sutures are made of fibrous tissue and allow for the growth of the skull during childhood, accommodating brain development. As a person ages, these joints gradually fuse completely, resulting in a solid structure for the adult skull. Examples of major sutures include the coronal, sagittal, and lambdoid sutures.
Suture joint ie skull sections are fused with suture joints
it is a joint that has little or no movement
So many joints have little or no movement. The joints between skull bones are there, probably to allow the increase in the size of the head. No movement is needed there. Movement may be harmful there. Once the growth is complete, the bones frequently get fused there, in case of skull bones.
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.
An example of a condyloid joint that is not in the human body is the atlanto-occipital joint found at the base of the skull in giraffes. This joint allows for a variety of movements like flexion, extension, lateral flexion, and rotation.

Suture joint ie skull sections are fused with suture joints
it is a joint that has little or no movement
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.
Your skull.
A fixed joint is a joint between two bones that doesn't move. A good example of this is in the skull - the skull plates don't move together or against each other, but they are connected or fused. Fixed joints are also called fused joints for this reason.

Fixed joints are called fixed joints because they are fixed and fused together. The are immovable. Two examples are the ilium (end of pelvic girdle) and the skull.
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.
Suture is a type of fibrous joint which only occurs in the skull (cranium). Only a tiny amount of movement is permitted at sutures, which contributes to the compliance and elasticity of the skull. On the other hand, joints are usually very flexible and can therefore move.
Yes, the lambdoidal suture is an immovable fibrous joint in the human skull. It connects the parietal bones to the occipital bone and provides stability and protection to the brain.
