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…
Definition The superior mesenteric plexus is a downward continuance of the celiac prevertebral plexus and refers to a complexity of neurons that is present near the root of the superior mesenteric artery and posterior aspect of the pancreas. Various secondary plexuses get arise here, which follow the route of the arterial branches of the superior…
Introduction The central nervous system (CNS) accommodates numerous nerve fibers that group together to form pathways between its different parts. These neural pathways show the communicating highways of the CNS. They can be located uniquely within the brain, giving connections between several of its structures, or they can link or connection between the brain and…

The function of the celiac plexus is to collect both parasympathetic and sympathetic put-in from the vagus nerve (CN X) and splanchnic nerves and…
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…
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…
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…

What is the Tibialis Anterior Muscle Pain? This tibialis anterior muscle pain produces by the muscle, which is situated at the front of the lower leg and is connected to the top of the foot.The patient feels the pain in this region is complicated by the shin splints, which produce pain on the inside of…
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,…
