Abstract
Hypophyseal triangles are of considerable interest not only in the field of human anatomy but also in the comparative anatomy.
Stated in the following are the findings of craniometric studies made on the dog.
The mean of∠NPBr in ΔPNBr of the dog was the largest being 68.2°±0.51 and∠PNBr was the smallest being 49.0°±0.43.
∠PBrL of ΔPBrL was the largest being 88.6°±0.52 and∠BrPL was the smallest being 29.1°±0.43.
Above findings were quite different from the human cases.
In the dog, ΔNPL forms an isosceles triangle with∠NPL as its vertical angle, while in the human being, Δ NBrL forms an isosceles triangle with∠NBrL as its vertical angle.
