Summary
This study precisely defines the masticator space anatomy to clarify mass syndromes. Accurate imaging aids radiologists in diagnosing lesions and avoiding suboptimal management.
Area of Science:
- Anatomy
- Radiology
- Head and Neck Surgery
Background:
- The masticator space, a deep facial region, possesses a complex anatomical structure.
- Current terminology for this area is often obsolete and confusing.
- Understanding its anatomy is crucial for accurate diagnosis and management of associated pathologies.
Purpose of the Study:
- To precisely define the masticator space anatomy.
- To clarify and illustrate common mass syndromes within this space.
- To provide a standardized terminology for the masticator space.
Main Methods:
- Review of anatomical literature.
- Analysis of imaging studies including multidetector computed tomography (CT) and magnetic resonance imaging (MRI).
- Correlation of imaging findings with clinical presentations of mass syndromes.
Main Results:
- Primary tumors are uncommon, typically benign, and of vascular or neural origin.
- Adjacent lesions, particularly pharyngeal, frequently extend into the masticator space.
- Odontogenic abscesses are the most common infectious pathology and lesion within the masticator space.
Conclusions:
- Precise definition of the masticator space improves diagnostic accuracy.
- Multidetector CT and MRI are essential for studying the space and its communications.
- Improved understanding aids radiologists in recognizing lesions, avoiding unnecessary surgery, and optimizing patient management.

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

01:11Oral Cavity
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

01:26Anatomy of the Gastrointestinal System
The human digestive system is an intricate and essential network for nutrient absorption and waste elimination. It encompasses the gastrointestinal (GI) tract and several accessory organs.

01:22Physiology of the Gastrointestinal System I: Ingestion and Propulsion
The physiology of the gastrointestinal system begins with ingestion as food enters the mouth.
01:26Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

01:13Microscopic Anatomy of Skeletal Muscles
Skeletal muscle cells, also called muscle fibers, are distinctly elongated, multi-nucleated, slender biological units. They are packed with specialized structures designed to facilitate their primary function, which is contraction.
The muscle sarcolemma is a plasma membrane enclosing each muscle cell that conducts electrical signals called action potentials. The sarcolemma extends into the cell to form T-tubules, ensuring the neural impulses are uniformly distributed across the entire muscle...
