sagittal suture

In forensic anthropology, the sagittal suture is one method used to date human remains.

The sagittal suture joins together the two parietal bones of skull.

Bregma- Mid line point where the coronal and sagittal sutures intersect.

All members have chloroplasts and a theca, which is composed of two large plates joined by a sagittal suture.

The vertex is the highest point on the skull and is often near the midpoint of the sagittal suture.

An increased A-P diameter indicates a malformed fusion of the sagittal suture.

Two anatomical landmarks are found on the sagittal suture: the bregma, and the vertex of the skull.

If the sagittal suture closes early the skull becomes long, narrow, and wedge-shaped, a condition called "scaphocephaly."

Premature sagittal suture closure restricts growth in a perpendicular plane, thus the head will not grow sideways and remain narrow.

The term obelion is applied to that point of the sagittal suture which is on a level with the parietal foramina.

The flexion point is located on the sagittal suture, 3 cm (about 1 inch) forward of the posterior fontanelle.

The sagittal suture is a dense, fibrous connective tissue joint between the two parietal bones of the skull.

It is a type of cephalic disorder which occurs when there is a premature fusion of the sagittal suture.

The sagittal suture is also known as the "interparietal suture" and the "sutura interparietalis."

Compensatory growth will occur sideways, due to the sagittal suture, and upwards, due to the lambdoid sutures.

"Sagittal suture."

Premature closure of the sagittal suture (the suture running the length of the skull) produces a long, narrow head.

In scaphocephaly the sagittal suture is prematurely fused, preventing the skull from growing perpendicular to the suture.

The point where the coronal suture intersects with the sagittal suture forms a T-shape and is called the bregma.

The five sutures are the two squamous, one coronal, one lambdoid, and one sagittal sutures.

Use the middle finger to identify the posterior fontanelle, then move the finger forward along the sagittal suture approximately 3 cm / 1 inch.

That point where the sagittal suture intersects the lambdoid suture is called the lambda, because of its resemblance to the Greek letter.

Another explanation would be the notching of the sagittal suture posteriorly by the lambdoidal suture -similar to feathers on an arrow.

The bregma is the anatomical point on the skull at which the coronal suture is intersected perpendicularly by the sagittal suture.

The bregma is located at the intersection of the coronal suture and the sagittal suture on the superior middle portion of the calvarium.
