It is also called the metopic suture, [1] [2] although this term may also refer specifically to a persistent frontal suture. [ 3 ] If the suture is not present at birth because both frontal bones have fused ( craniosynostosis ), it will cause a keel-shaped deformity of the skull called trigonocephaly .
Metopism is the condition of having a persistent metopic suture, [2] or persistence of the frontal metopic suture in the adult human skull. [3] Metopism is the opposite of craniosynostosis. [4] The main factor of the metopic suture is to increase the volume of the anterior cranial fossa.
This foramen varies in size in different subjects, and is frequently impervious; when open, it transmits a vein from the nose to the superior sagittal sinus. On either side of the middle line the bone presents depressions for the convolutions of the brain, and numerous small furrows for the anterior branches of the middle meningeal vessels.

Metopic synostosis is a factor in 5% to 15% of cases, and lambdoid synostosis is seen in 0% to 5% of nonsyndromic cases. [ 3 ] Five to 15% of the time more than one suture is involved; this is referred to as "complex craniosynostosis" and is typically part of a syndrome.
In human anatomy, the superior mesenteric vein (SMV) is a blood vessel that drains blood from the small intestine (jejunum and ileum). Behind the neck of the pancreas , the superior mesenteric vein combines with the splenic vein to form the portal vein that carries blood to the liver .

The inferior mesenteric vein connects in the majority of people on the splenic vein, but in some people, it is known to connect on the portal vein or the superior mesenteric vein. Roughly, the portal venous system corresponds to areas supplied by the celiac trunk , the superior mesenteric artery , and the inferior mesenteric artery .
