  • The Muscular System Views
    1 PRE-LAB EXERCISES Before coming to lab, get familiar with a few muscle groups we’ll be exploring during lab. Using Visible Body’s Human Anatomy Atlas, go to the Views section. Under Systems, scroll down to the Muscular System views. Select the view Expression and find the following muscles. When you select a muscle, note the book icon in the content box. Selecting this icon allows you to read the muscle’s definition. 1. Occipitofrontalis (epicranius) 2. Orbicularis oculi 3. Orbicularis oris 4. Nasalis 5. Zygomaticus major Return to Muscular System views, select the view Head Rotation and find the following muscles. 1. Sternocleidomastoid 2. Scalene group (anterior, middle, posterior) 2 IN-LAB EXERCISES Use the following modules to guide your exploration of the head and neck region of the muscular system. As you explore the modules, locate the muscles on any charts, models, or specimen available. Please note that these muscles act on the head and neck – those that are located in the neck but act on the back are in a separate section. When reviewing the action of a muscle, it will be helpful to think about where the muscle is located and where the insertion is. Muscle physiology requires that a muscle will “pull” instead of “push” during contraction, and the insertion is the part that will move. Imagine that the muscle is “pulling” on the bone or tissue it is attached to at the insertion. Access 3D views and animated muscle actions in Visible Body’s Human Anatomy Atlas, which will be especially helpful to visualize muscle actions.

    EDS Awareness in the TMJ Patient TMJ and CCI with the EDS Patient “The 50/50” Myofascial Pain Syndrome EDNF, Baltimore, MD August 14,15, 2015 Generation, Diagnosis and Treatment of Head Pain of Musculoskeletal Origin Head pain generated by: • Temporomandibular joint dysfunction • Cervicocranial Instability • Mandibular deviation • Deflection of the Pharyngeal Constrictor Structures Parameters & Observations . The Myofascial Pain Syndrome (MPS) is a description of pain tracking in 200 Ehlers-Danlos patients. Of the 200 patients, 195 were afflicted with this pain referral syndrome pattern. The MPS is in direct association and correlation to Temporomandibular Joint dysfunction and Cervico- Cranial Instability syndromes. Both syndromes are virtually and always correlated. Evaluation of this syndrome was completed after testing was done to rule out complex or life threatening conditions. The Temporomandibular Joint TMJ Dysfunction Symptoms: Deceptively Simple, with Complex Origins 1) Mouth opening, closing with deviation of mandibular condyles. -Menisci that maybe subluxated causing mandibular elevation. -Jaw locking “open” or “closed”. -Inability to “chew”. 2) “Headaches”/”Muscles spasms” (due to decreased vertical height)generated in the temporalis muscle, cheeks areas, under the angle of the jaw. 3) Osseous distortion Pain can be generated in the cheeks, floor of the orbits and/or sinuses due to osseous distortion associated with “bruxism”.

Methods: ninety patients (64 women, 26 men; mean age: 39.36 ± 15.40 years), including 45 patients with symptoms of TMD after whiplash injury (wTMD), and 45 age- and sex- matched controls with TMD due to idiopathic causes (iTMD) were included. TMD was diagnosed using the study diagnostic criteria for TMD Axis I, and MRI findings of the TMJ and masticatory muscles were investigated. To evaluate the severity of TMD pain and muscle tenderness, we used a visual analog scale (VAS), palpation index (PI), and neck PI. Results: TMD indexes, including VAS, PI, and neck PI were significantly higher in the wTMD group. In the wTMD group, muscle tenderness was highest in the masseter muscle (71.1%), and muscle tenderness in the temporalis (60.0%), lateral pterygoid muscle (LPM) (22.2%), and medial pterygoid muscle (15.6%) was significantly more frequent than that in the iTMD group (all p < 0.05).

  • The Mandibular Nerve - Vc Or VIII by Prof
    The Mandibular Nerve - Vc or VIII by Prof. Dr. Imran Qureshi The Mandibular nerve is the third and largest division of the trigeminal nerve. It is a mixed nerve. Its sensory root emerges from the posterior region of the semilunar ganglion and is joined by the motor root of the trigeminal nerve. These two nerve bundles leave the cranial cavity through the foramen ovale and unite immediately to form the trunk of the mixed mandibular nerve that passes into the infratemporal fossa. Here, it runs anterior to the middle meningeal artery and is sandwiched between the superior head of the lateral pterygoid and tensor veli palatini muscles. After a short course during which a meningeal branch to the dura mater, and the nerve to part of the medial pterygoid muscle (and the tensor tympani and tensor veli palatini muscles) are given off, the mandibular trunk divides into a smaller anterior and a larger posterior division. The anterior division receives most of the fibres from the motor root and distributes them to the other muscles of mastication i.e. the lateral pterygoid, medial pterygoid, temporalis and masseter muscles. The nerve to masseter and two deep temporal nerves (anterior and posterior) pass laterally above the medial pterygoid. The nerve to the masseter continues outward through the mandibular notch, while the deep temporal nerves turn upward deep to temporalis for its supply. The sensory fibres that it receives are distributed as the buccal nerve. The 1 | P a g e buccal nerve passes between the medial and lateral pterygoids and passes downward and forward to emerge from under cover of the masseter with the buccal artery.

  • The Muscles of the Jaw Are Some of the Strongest in the Human Body
    MUSCLES OF MASTICATION The muscles of the jaw are some of the strongest in the human body. They aid in chewing and speech by allowing us to open and close our mouths. Ready to unlock the mysteries of mastication? Then read on! OF MASSETERS AND MANDIBLES The deep and superficial masseter muscles enable mastication (chewing by pulling the mandible (jawbone) up towards the maxillae. Factoid! Humans’ jaws are able to bite with DEEP a force of about 150-200 psi (890 MASSETER Newtons). In contrast, a saltwater crocodile can bite with a force of 3,700 SUPERFICIAL psi (16, 400 Newtons)! MASSETER MAXILLA (R) 2 MANDIBLE MORE MASSETER FACTS The deep masseter’s origin is the zygomatic arch and the superficial masseter’s origin is the zygomatic bone. Both masseters insert into the ramus of the mandible, though the deep masseter’s insertion point is closer to the temporomandibular joint. The mandible is the only bone in the skull that we can consciously move (with the help of muscles, of course). 3 TEMPORALIS The temporalis muscles sit on either side of the head. Their job is to elevate and retract the mandible against the maxillae. They originate at the temporal fossa and temporal fascia and insert at the coronoid process and ramus of the mandible. 4 LATERAL SUPERIOR PTERYGOIDS HEAD The lateral pterygoids draw the mandibular condyle and articular disc of the temporomandibular joint forward. Each lateral pterygoid has two heads. The superior head originates at the sphenoid and infratemporal crest and the inferior head originates at the lateral pterygoid plate.

  • The Independent Functions of the Two Heads of the Lateral Pterygoid Muscle
    The Independent Functions of the Two Heads of the Lateral Pterygoid Muscle JAMES A. McNAMARA, JR. Department of Anatomy and Center for Human Growth and Development, The University of Michigan, Ann Arbor, Michigan 48104 ABSTRACT Investigations on the role of the lateral pterygoid muscle in mandibular movements have been limited due to difficulties in obtaining con- sistent neuromuscular recordings in human subjects. The rhesus monkey was used as a substitute experimental animal. Thirty-three Macaca mulatta were monitored in 113 electromyographic recording sessions. Two distinct functional patterns were identified from the region of the lateral pterygoid muscle, depend- ing upon the location of the electrodes within this muscle. Through anatomical dissection of areas of electrode placement in 12 animals, the two patterns of activity were related to the inferior and superior heads of the lateral pterygoid muscle. The inferior head acted synergistically with the suprahyoid muscle group in opening movements of the mandible. No activity was noted in closing movements, or in swallowing. In contrast, the superior head was not active dur- ing opening movements. Electromyographic activity of the superior head, an- tagonistic to the suprahyoid muscles, was observed during such closing move- ments as chewing and clenching of the teeth and during deglutition. The superior head presumably positioned or stabilized the condylar head and disc against the articular eminence during closing movements of the mandible, while the in- ferior head assisted in the translation of the condylar head downward, anteriorly, and contralaterally during opening movements. Thus, the two heads of the lateral pterygoid can be considered as two functionally distinct muscles.

  • The Mandibular Nerve: the Anatomy of Nerve Injury and Entrapment
    5 The Mandibular Nerve: The Anatomy of Nerve Injury and Entrapment M. Piagkou1, T. Demesticha2, G. Piagkos3, Chrysanthou Ioannis4, P. Skandalakis5 and E.O. Johnson6 1,3,4,5,6Department of Anatomy, 2Department of Anesthesiology, Metropolitan Hospital Medical School, University of Athens Greece 1. Introduction The trigeminal nerve (TN) is a mixed cranial nerve that consists primarily of sensory neurons. It exists the brain on the lateral surface of the pons, entering the trigeminal ganglion (TGG) after a few millimeters, followed by an extensive series of divisions. Of the three major branches that emerge from the TGG, the mandibular nerve (MN) comprises the 3rd and largest of the three divisions. The MN also has an additional motor component, which may run in a separate facial compartment. Thus, unlike the other two TN divisions, which convey afferent fibers, the MN also contains motor or efferent fibers to innervate the muscles that are attached to mandible (muscles of mastication, the mylohyoid, the anterior belly of the digastric muscle, the tensor veli palatini, and tensor tympani muscle). Most of these fibers travel directly to their target tissues. Sensory axons innervate skin on the lateral side of the head, tongue, and mucosal wall of the oral cavity. Some sensory axons enter the mandible to innervate the teeth and emerge from the mental foramen to innervate the skin of the lower jaw. An entrapment neuropathy is a nerve lesion caused by pressure or mechanical irritation from some anatomic structures next to the nerve. This occurs frequently where the nerve passes through a fibro-osseous canal, or because of impingement by an anatomic structure (bone, muscle or a fibrous band), or because of the combined influences on the nerve entrapment between soft and hard tissues.

  • Dental Occlusion As One Cause of Tinnitus T Jose Luiz Villaça Avoglio
    Medical Hypotheses 130 (2019) 109280 Contents lists available at ScienceDirect Medical Hypotheses journal homepage: www.elsevier.com/locate/mehy Dental occlusion as one cause of tinnitus T Jose Luiz Villaça Avoglio Private practice of Orthodontics, Guaratingueta, Brazil ABSTRACT There is large support in literature linking tinnitus to dental occlusion and temporomandibular joint disorders (TMD). However, there is no model to explain such a link. This hypothesis explains how the fusimotor system of the muscles innervated by the trigeminal motor nucleus is affected by inadequacies in the occlusion of the teeth that cause changes in posture and movement of the mandible. Reptile to mammal evolution shows that stomatognathic structures underwent changes related to mastication. Among several changes, there was the appearance of a new articulation between the mandible and skull: the temporomandibular joint. The bones of the old reptile joint, quadrate-articular, have detached from the mandible and are part of the middle ear bone chain. The former becomes the incus and the latter the malleus. This bone change also carried the tensor tympani and its trigeminal motor innervation. Inadequate occlusal contacts give rise to an adapted function of the mandible and the most common compensatory muscular response is hypertonia involving all mandibular muscles, including the tensor tympani. A fundamental clinical feature that demonstrates the involvement of the trigeminal fusimotor system is the characteristic pain by palpation, but no pain on the mandibular movement. Muscle pain is always felt in the dermatome innervated by the mandibular branch of the trigeminal nerve, which carries the motor fibers, reported as tightening, similar to cramp, and has regular behavior in intensity, duration and frequency.
