Medial Pterygoid muscle

Introduction The medial pterygoid muscles, a major elevator of the jaw is a square-shaped masticatory muscle, encountered on the medial part of the lower jaw bilaterally. It is also known as the internal pterygoid muscles. These muscles lie medial to the lateral pterygoid muscles. The medial pterygoid muscle is a thick quadrilateral muscle that binds…

Lateral Pterygoid muscle

Introduction The lateral pterygoid muscle is a craniomandibular muscle that plays an essential role in the inferior temporal region. It is active during mastication and mandibular motions – including protrusion (forward movement of the mandible), abduction (depression of the mandible), and mediotrusion (mandibular condyle movement towards the midline). It functions particularly during speaking, singing, and…

Temporalis Muscle

Introduction In anatomy, the temporalis muscles, also known as the temporal muscle, are one of the muscles of mastication (chewing). It is a broad, fan-shaped convergent muscle on the individual side of the head that fills the temporal fossa, superior to the zygomatic arch so it obscures much of the temporal bone. Temporal guides to…

Seizures

What are Seizures? A seizure is a medical situation where you have a temporary, unstoppable surge of electrical activity in your brain. When that occurs, the involved brain cells uncontrollably fire signals to others near them. This type of electrical activity overloads the involved regions of your brain. That overload can generate a broad range…

Masseter muscle

Introduction In human anatomy, the masseter muscle is one of the muscles of mastication. Found exclusively in mammals, it is particularly powerful in herbivores to encourage the chewing of plant matter. The most obvious muscle of mastication is the masseter muscle since it is the most superficial and one of the most powerful. Origin of…

Maffucci syndrome

What is Maffucci syndrome? Maffucci syndrome is a disease that primarily involves the bones and skin. It is represented by multiple enchondromas (benign enlargements of cartilage), bone malformations, and hemangiomas (tangles of abnormal blood vessels). The abnormal growths with Maffucci syndrome may become cancerous (malignant). Certain, involved people may develop bone cancers known as chondrosarcomas,…

Medial Rectus Muscle

Introduction The medial rectus muscle is a muscle that is in the orbit near the eye. It is an extraocular muscle of the eye. It arises from the ordinary tendinous ring and inserts into the anteromedial surface of the eye. It is innervated by the inferior division of the oculomotor nerve (III). It rotates the eye medially (adduction). Origin and Insertion of Medial Rectus…
