The '''Procerus''' is a small pyramidal slip of muscle deep to the [[superior orbital nerve]], [[Supra-orbital artery|artery]] and [[Supraorbital vein|vein]].
==Origin and insertion==
It arises by [[tendon|tendinous]] fibers from the [[fascia]] covering the lower part of the [[nasal bone]] and upper part of the [[lateral nasal cartilage]].
It is inserted into the skin over the lower part of the [[forehead]] between the two [[eyebrows]], its fibers [[decussating]] with those of the [[Frontalis]].
==Function==
It helps to pull that part of the skin between the eyebrows downwards, which assists in flaring the [[nostrils]].
It can also contribute to an expression of [[anger]].
