sinciput
The front part of the head or skull (as contradistinct from occiput).
Such lesions have been considered to be inoperable when they involved the sinciput.
The cranial anomalies occurred either in the occiput or the sinciput, approximately twice as often in the occiput as in the sinciput.
Where it comes from
Borrowed from Latin sinciput (“half a head”; “smoked hog’s cheek or half-jowl”; (transferred senses): “brain”, “head”), whence also the French sinciput.
