Summary
The mandibular preangular notch is found in nearly 90% of individuals, often asymmetrically. This anatomical feature
Area of Science:
- Anatomy
- Anthropology
- Forensic Science
Background:
- The mandibular preangular notch is a distinct anatomical feature of the human mandible.
- Understanding its morphology is crucial for various medical and forensic applications.
- Previous studies have provided limited data on the prevalence and detailed characteristics of this notch.
Purpose of the Study:
- To conduct a detailed analysis of the mandibular preangular notch in a large human cadaver sample.
- To determine the prevalence, shape, and sexual dimorphism of the preangular notch.
- To provide anatomical data relevant for surgical and forensic contexts.
Main Methods:
- Macroscopic examination of 273 human cadaver mandibles.
- Detailed analysis of the preangular notch's presence, shape, symmetry, depth, and length.
- Statistical comparison of notch characteristics between sexes and sides.
Main Results:
- The preangular notch was present in approximately 90% of the analyzed mandibles.
- The notch was predominantly asymmetric and elliptical in shape.
- Males exhibited greater depth and length in the anterior part of the notch; the right side showed greater depth irrespective of sex.
Conclusions:
- The mandibular preangular notch is a highly prevalent anatomical landmark.
- Significant sexual dimorphism exists in notch dimensions, with males showing larger measurements.
- This detailed anatomical knowledge is valuable for surgeons performing reconstructive and plastic procedures on the mandible.

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.

01:08Overview of the Skull
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
