Identifiers Latin Musculus sternocleidomastoideus TA A04.2.01.008 FMA 13407 Anatomical terms of muscle [edit on Wikidata] In human anatomy, the sternocleidomastoid muscle (/ˌstɜːrnoʊˌklaɪdəˈmæsˌtɔɪd, -nə-, -doʊ-/), also known as sternomastoid and commonly abbreviated as SCM, is a paired muscle in the superficial layers of the side of the neck. It is one of the largest and most superficial cervical muscles. The primary actions of the muscle are rotation of the head to the opposite side and flexion of the neck. The sternocleidomastoid is innervated by the accessory nerve. It is given the name sternocleidomastoid because it originates at the manubrium of the sternum (sterno-) and the clavicle (cleido-), and has an insertion at the mastoid process of the temporal bone of the skull.

Epicranial aponeurosis

Epicranial aponeurosis Muscles of the head, face, and neck. (Epicranial aponeurosis visible at top.) Details Identifiers Latin Galea aponeurotica, Aponeurosis epicranialis, Aponeurosis epicrania TA A04.1.03.007 FMA 46768 Anatomical terminology [edit on Wikidata] This article includes a list of references, related reading or external links, but its sources remain unclear because it lacks inline citations. Please help to improve this article by introducing more precise citations. (May 2015) (Learn how and when to remove this template message) The epicranial aponeurosis (aponeurosis epicranialis, galea aponeurotica) is an aponeurosis (a tough layer of dense fibrous tissue) which covers the upper part of the cranium in humans and various other animals. In humans, it is attached, in the interval between its union with the occipitofrontalis muscle, to the external occipital protuberance and highest nuchal lines of the occipital bone; in front, it forms a short and narrow prolongation between its union with the frontalis muscle or frontal part of the occipitofrontalis muscle. On either side it gives origin to the anterior and the superior auricular muscles; in this situation it loses its aponeurotic character, and is continued over the temporal fascia to the zygomatic arch as a layer of laminated areolar tissue. It is closely connected to the integument by the firm, dense, fibro-fatty layer which forms the superficial fascia of the scalp: it is attached to the pericranium by loose cellular tissue, which allows the aponeurosis, carrying with it the integument, to move through a considerable distance.

Mentalis

Mentalis Muscles of the head, face, and neck. Details Origin anterior mandible Insertion chin Nerve mandibular branch of facial nerve Actions elevates and wrinkles skin of chin, protrudes lower lip Identifiers Latin musculus mentalis TA A04.1.03.037 FMA 46825 Anatomical terms of muscle [edit on Wikidata] This article relies largely or entirely upon a single source. Relevant discussion may be found on the talk page. Please help improve this article by introducing citations to additional sources. (May 2015) The mentalis is a paired central muscle of the lower lip, situated at the tip of the chin. It originates from the mentum and inserts into the chin soft tissue. The primary effect of the mentalis contraction is the upward-inward movement of the soft tissue complex of the chin, which raises the central portion of the lips in turn. In the setting of lip incompetence (the upper and lower lips do not touch each other at rest), the mentalis muscle contraction can bring temporary but strained oral competence. In conjunction with orbicularis contraction, the mentalis muscle allows the lips to "pout." Externally, mentalis contraction causes wrinkling of the chin skin, as used in expressions of doubt or displeasure. It is sometimes referred to as the "pouting muscle." Geniospasm is a genetic movement disorder of the mentalis muscle. More details Android, Windows

Details Origin Maxilla Insertion Nasal bone Artery Superior labial artery Nerve Buccal branch of the facial nerve Actions Compresses bridge, depresses tip of nose, elevates corners of nostrils Identifiers Latin musculus nasalis TA A04.1.03.009 FMA 46770 Anatomical terms of muscle [edit on Wikidata] The nasalis is a sphincter-like muscle of the nose whose function is to compress the nasal cartilages. It is the muscle responsible for "flaring" of the nostrils. Some people can use it to close the nostrils to prevent entry of water when underwater. It consists of two parts, transverse and alar: The transverse part (compressor naris) arises from the maxilla, above and lateral to the incisive fossa; its fibers proceed upward and medially, expanding into a thin aponeurosis which is continuous on the bridge of the nose with that of the muscle of the opposite side, and with the aponeurosis of the Procerus. It compresses the nostrils and may completely close them. The alar part "Dilator nasalis". arises from the maxilla over the lateral incisor and inserts into the greater alar cartilage. Its medial fibres tend to blend with the depressor septi, and has been described as part of that muscle. ^ -1945763781 at GPnotebook More details Android, Windows

Occipitofrontalis muscle

Occipitofrontalis Details Origin Two occipital bellies and two frontal bellies. Insertion Galea aponeurotica Artery Frontal belly: supraorbital and supratrochlear arteries Occipital belly: Occipital artery Nerve Facial nerve Actions Raises eyebrows, wrinkles forehead Identifiers Latin Musculus occipitofrontalis or Musculus epicranii venter frontalis TA A04.1.03.003 FMA 9624 Anatomical terms of muscle [edit on Wikidata] The occipitofrontalis muscle (epicranius muscle) is a muscle which covers parts of the skull. It consists of two parts or bellies: The occipital belly, near the occipital bone, and the frontal belly, near the frontal bone. In humans, the occipitofrontalis only serves for facial expressions. Some sources consider the occipital and frontal bellies to be two distinct muscles. However, Terminologia Anatomica currently classifies it as a single muscle, and also includes the temporoparietalis muscle as part of the epicranius. The occipitofrontalis muscle receives blood from several arteries. The frontal belly receives blood from the supraorbital and supratrochlear arteries, while the occipital belly receives blood from the occipital artery. The occipitofrontalis muscle is innervated by the facial nerve. More details Android, Windows
