Nasal process

The nasal process (processus nasalis) of the incisive bone, formerly called 'the rising branch'  is more developed than the palatine process. Flattened from one side to the other, it rises on the side of the rostral opening of the nasal cavity, towards the nasal bone.

Its lateral surface is smooth, more or less convex; it is continued without demarcation with the labial surface of the body of the incisive bone.

The medial surface, more or less concave, takes part to delimit the nasal cavity.

The rostral border is smooth and rounded, sometimes sharp.

The caudal border is rough and beveled to unite to the maxilla.

The top is variable; in most species is forms a more or less long bevel that responds to the lateral border of the nasal bone, with which it takes part in determining the naso-incisive notch (incisura nasoincisiva).

In Ruminants, it hardly reaches the neighborhood of the nasal bone and forms a more or less rounded spike.
