The masticatory muscles consist of four paired muscles that are part of the skeletal musculature and are called musculi masticatorii in medical terminology. They move the lower jaw and enable chewing and grinding movements. What is the masticatory musculature? The masseter, temporalis, medial pterygoid and lateral pterygoid muscles belong to the masticatory muscles. They are … Masticatory Muscles: Structure, Function & Diseases
The digastric muscle, as part of the head, specifically the upper tongue muscles, is responsible for mouth and jaw joint mobility. In addition, it influences swallowing, speaking, and yawning and voice production. If the digastric muscle is tense, mild to even severe complaints can occur over the body, which are not always directly assigned to … Digastric Muscle: Structure, Function & Diseases
Teeth have an important job. They have to grind and chew the food we eat every day. In order to perform this task, they must be stably anchored in the jaw. What is the periodontium? The term periodontium, also known as the dental bed or periodontium, is the generic term for various supporting tissues that … Periodontium: Structure, Function & Diseases
Located in the midbrain, the pedunculi cerebri are composed of the cerebral peduncles (crura cerebri) and the midbrain cap (tegmentum mesencephali). Lesions in these areas can be associated with a variety of conditions, depending on which structures are affected. For example, Parkinson’s disease results from atrophy of the substantia nigra in the tegmentum and typically … Pedunculi Cerebri: Structure, Function & Diseases
The biting force of man seems to be almost effeminate nowadays. This could at least be assumed if a look is taken at modern eating habits, which are nevertheless apparently strongly opposed to those of past times. Among early man, for example, there was the paranthropus, whose cheekbones were four times larger than those of … Biting Force: Function, Tasks, Role & Diseases
Canine guidance is part of occlusion (closure, occlusion), the contact between the teeth of the lower and upper dentition. The canines provide the glide path for the antagonistic (opposing) teeth and guide the lower jaw, while there is no contact between the posterior teeth. What is canine guidance? Canine guidance is part of occlusion, the … Canine Guidance: Function, Tasks, Role & Diseases
The pterygoid medialis muscle is a muscle that belongs to the masticatory musculature in humans. It is located on the inside of the temporomandibular joint. Its function is to move the temporomandibular joint. What is the pterygoid medialis muscle? The pterygoid medialis muscle is a masseter muscle of the human dentition. Thus, it has an … Medial Pterygoid Muscle: Structure, Function & Diseases
The teeth of the lower jaw normally meet those of the upper jaw in what is called the occlusal plane. Deviations from this plane of contact are called nonocclusions and are malocclusions of the dentition. Causes include dental anomalies, facial skeletal anomalies, and dental trauma. What is nonocclusion? Occlusion is the term dentistry uses to … Nonocclusion: Function, Tasks, Role & Diseases
The canines and incisors of the human dentition are called anterior teeth. If the inclination of the tooth axis of the maxillary anterior teeth has a mirror symmetrical center line, an aesthetic and harmonious dental appearance results. The technical language speaks of an anterior tooth guide when canines and incisors serve as guides during bite … Anterior Tooth Guidance: Function, Tasks, Role & Diseases
Latin: Musculus temporalis Definition The temporal muscle is the strongest jaw-closer of the chewing muscles. This skeletal muscle works together with the masticatory muscle and the inner wing muscle to close the jaw and additionally pushes it backwards (so-called retrograde movement). History Base: mandible (Processus coronoideus mandibulae) Origin: temporal fossa (lateral surface of the skull) … Temporal Muscle
The masseter muscle is one of four muscles of mastication. The skeletal muscle is involved in the comminution of food and in the salivary passage of the food pulp. The masseter muscle can be affected by pathological tension to lockjaw, as well as inflammation and paralysis. What is the masseter muscle? Skeletal muscles are largely … Musculus Masseter: Structure, Function & Diseases
Definition The trigeminal nerve is one of the most important nerves in the human body. It is counted among the so-called brain nerves. These are characterized by the fact that they all originate directly from the brain stem. The main task of the trigeminal nerve is, in addition to the nervous supply (innervation) of the … Trigeminal Palsy
