Each human normally has the two nasal bones which are located between the upper jaw (maxillary) bones’ frontal processes, in upper-middle of the face area which gives the nose bone anatomy. These sit in the midline to one other to form a bridge of a nose. The nasal bones are oblong and small but can vary in shape and size in different people. Every nasal bone’ function is to fix together the cartilage which forms the individual nose shapes and contours.
Every nasal bone normally has four bones that form joints, this includes two facial bones and two crania. The cranium bones can also be called the frontal and ethmoid. The facial bones can be called the opposite and maxilla nasal. Every nasal bone has the borders which include the superior, inferior, medial and lateral. Every nasal bone normally has two surfaces which are the outer and inner surface.
An outer surface of a nasal bone is covered by procerus muscles and compressor naris, which is convex from one side to side and also concavo-convex from the bottom to top. It has the hole at the center, through here the small vein pass. The inner surface travels downward which has the groove which allows in one branch of a nasociliary nerve. The surface is concave from the two sides.
When talking about the nose bone anatomy, every nasal bone is normally developed from the single center that appears about the eight week in a membrane overlying fronto-nasal cartilage. A cartilage that is continuous with ethmoid cartilage above together with a lateral cartilage of a nose below. The sub-sequently undergoes the absorption because of the pressure which is caused by expanding bone. During birth, nasal bones are virtual as they’re long, whereas, in adult, the length is actually three times greater when you compare it to the width.
