Orbicularis oris muscle. Inferior labial artery and superior labial artery. It is sometimes known as the kissing muscle[ 1] because it is used to pucker the lips. In human anatomy, the orbicularis oris muscle is a complex of muscles in the lips that encircles the mouth. [ 2] It is not a true sphincter, as was once thought, as it is actually ...

The nerves of the scalp, face, and side of neck. The buccal branches of the facial nerve (infraorbital branches), are of larger size than the rest of the branches ...
Orbicularis oris: Tissue surrounding lips: Underneath skin at corners of the mouth Lateral movement of cheeks (e.g., sucking on a straw; also used to compress air in mouth while blowing) Cheeks: Lateral: Buccinator: Maxilla, mandible; sphenoid bone (via pterygomandibular raphae) Orbicularis oris: Pursing of lips by straightening them laterally ...
The orbicularis oculi is a muscle in the face that closes the eyelids. It arises from the nasal part of the frontal bone, from the frontal process of the maxilla in front of the lacrimal groove, and from the anterior surface and borders of a short fibrous band, the medial palpebral ligament . From this origin, the fibers are directed laterally ...
The facial nerve, also known as the seventh cranial nerve, cranial nerve VII, or simply CN VII, is a cranial nerve that emerges from the pons of the brainstem, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue. [1] [2] The nerve typically travels from the ...
In the fibers of the orbicularis oris: Artery: Buccal artery: Nerve: Buccal branch of the facial nerve (VII cranial nerve) Actions: The buccinator compresses the cheeks against the teeth and is used in acts such as blowing. It is an assistant muscle of mastication (chewing) and in neonates it is used to suckle. Identifiers; Latin: musculus ...
Satchmo's syndrome is a disorder due to the rupture of orbicularis oris muscle in trumpet players. [ 1] This syndrome is named after the nickname of Louis Armstrong, the trumpet player from New Orleans, because apparently it fits with the symptoms he experienced in 1935.
The Snout reflex (also orbicularis oris reflex[ 1]) or a " Pout " is a pouting or pursing of the lips that is elicited by light tapping of the closed lips near the midline. The contraction of the muscles causes the mouth to resemble a snout . This reflex is tested in a neurological exam and if present, is a sign of brain damage or dysfunction ...
