Neck of pancreas
Encyclopedia
The neck of pancreas springs from the right upper portion of the front of the head.
It is about 2.5 cm. long, and is directed at first upward and forward, and then upward and to the left to join the body; it is somewhat flattened from above downward and backward.
Its antero-superior surface supports the pylorus
; its postero-inferior surface is in relation with the commencement of the portal vein; on the right it is grooved by the gastroduodenal artery
. It is at the same level as the transpyloric plane

Transpyloric plane
An upper transverse line also known as Addison's Plane, is located halfway between the jugular notch and the upper border of the pubic symphysis; this indicates the margin of the transpyloric plane, which in most cases cuts through the pylorus, the tips of the ninth costal cartilages and the lower...
