What is Nasalis?

Salis is one of the muscles in the nose and consists of two parts, transverse or compressor NARIS and alar or depression NARIS. The nostrils are compressed and attracted towards the septum of the transverse part of Nasalis. Alar's part extends or flares, nostrils. It is attached to a thin structure of similar strain or aponeurosis over the bridge of the nose. Alar, or "wing -like" part of Nasalis, connects to one end to a larger cartilage, lying on the nose just above the nostril and attaching to the skin on the tip of the nose at the other end. Like all facial muscles, it is innervated by the upper buccal branches of the facial nerve or the cranial nerve VII. Blood is supplied with artery face. The muscle also plays a role in the formation of facial expressions from smiling to frowning. He often works with the help of other nose muscles such as Procerus, Levator Labia Superioris alaeque NAS and depression septi nasi.

Procerus is another noseThe muscle that wrinkles the upper part of the nose and during the frost or squint attracting the eyebrows down. It helps Salis pull the nostrils out and ignite them in the expression of anger. The levator Labii Superioris, nicknamed "Elvis Muscle", helps to expand the nostrils because of its role in creating a culminated expression. The depression septi nasi connects to the septum at one end and above the incisors in the upper jaw at the other end and helps pull the tip of the nose down and ignite the nostril.

After a cosmetic injection of the product, such as Botox® to the forehead, the Salisovercopensor can loss of muscle movement on the forehead and during the facial expressions. This can cause an unintentional side effect of cosmetic surgery known as a bunny or horizontal wrinkles across the nose bridge that may occur during a smile. Bunny lines can also develop naturally with age. To avoid these wrinkles, the doctor can ask Botox® into the transverse nasalis to paralyze the muscles.
