The levator labii superioris alaeque nasi muscle (occasionally shortened alaeque nasi muscle) is, translated from Latin, the "lifter of both the upper lip and of the wing of the nose". The muscle is attached to the upper frontal process of the maxilla and inserts into the skin of the lateral part of the nostril and upper lip. [ 1 ]

The zygomaticus major muscle is a muscle of the face. It arises from either zygomatic arch ; it inserts at the corner of the mouth. It is innervated by branches of the facial nerve (cranial nerve VII). It is a muscle of facial expression, which draws the angle of the mouth superiorly and posteriorly to allow one to smile. Bifid zygomaticus ...
It passes anterior-ward deep to the platysma and depressor anguli oris muscles. It provides motor innervation to muscles of the lower lip and chin: the depressor labii inferioris muscle, depressor anguli oris muscle, and mentalis muscle. [1] It communicates with the mental branch of the inferior alveolar nerve. [citation needed]
Branches of the facial nerve (which gives the motor supply to the muscles of facial expression) run through the substance of the parotid gland and so this is manifest as a transient facial palsy. The pterygomandibular space is one of the possible spaces into which a tooth may be displaced into during dental extraction , e.g. of a maxillary ...
The panniculus carnosus is a part of the subcutaneous tissues in vertebrates.It is a layer of striated muscle deep to the panniculus adiposus.

The platysma muscle lies just deep to the subcutaneous fascia and fat. [1] [3] It covers many structures found deeper in the neck, such as the external carotid artery, the external jugular vein, [4] the parotid gland, [4] the lesser occipital nerve, [4] the great auricular nerve, [4] and the marginal mandibular branch of the facial nerve.
