Sutural

Sutural is a term used in anatomy to describe a type of joint found in the human body. These joints, also known as sutures, are found primarily in the skull, where they connect the various bony plates that make up the cranium.

Anatomy

Sutural joints are fibrous joints that are only found in the skull. They are characterized by their short connective tissue fibers, which allow for very little movement. This is important in the skull, as it helps to protect the brain from injury.

The sutures of the skull are named for the bones they connect. For example, the sagittal suture connects the two parietal bones, while the coronal suture connects the frontal bone to the parietal bones.

Function

The primary function of sutural joints is to provide a strong, protective casing for the brain. The limited movement allowed by these joints helps to absorb shock and prevent injury.

In addition to their protective function, sutures also play a role in the growth of the skull. During infancy and childhood, the sutures are not fully fused, allowing for the skull to expand as the brain grows.

Clinical significance

In some cases, the sutures of the skull can fuse prematurely, a condition known as craniosynostosis. This can lead to abnormal skull shape and potential developmental issues. Treatment typically involves surgery to separate the fused sutures.
