Sphenoethmoidal suture

Sphenoethmoidal suture is a cranial suture that separates the sphenoid bone and the ethmoid bone. It is a fibrous joint that connects the sphenoid and ethmoid bones of the human skull.

Etymology

The term "sphenoethmoidal suture" is derived from the Greek words "sphen", meaning wedge, and "ethmoid", meaning sieve-like. The term "suture" comes from the Latin "sutura", meaning seam.

Anatomy

The sphenoethmoidal suture is located at the junction of the sphenoid and ethmoid bones, in the anterior cranial fossa. It is a small, almost vertical suture that is often difficult to see due to its location deep within the skull. The suture is important in the formation and growth of the skull, as it allows for the expansion of the brain and the skull during development.

Clinical Significance

The sphenoethmoidal suture, like other cranial sutures, can be used as a landmark in neurosurgery and radiology. It can also be involved in certain medical conditions. For example, premature closure of the sphenoethmoidal suture (a condition known as craniosynostosis) can lead to abnormal skull shape and potentially cause increased intracranial pressure and developmental delays.
