Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

7.6K
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...

Cranial Bones: Superior and Posterior View

8.3K
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,...

Overview of the Skull01:08

Overview of the Skull

8.3K
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...

Sutures of the Skull01:22

Sutures of the Skull

13.7K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Muscles for Facial Expressions01:14

Muscles for Facial Expressions

5.3K
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

Olfactory Receptors: Location and Structure01:03

Olfactory Receptors: Location and Structure

12.4K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Area of Science:

  • Anthropology
  • Forensic Science
  • Radiology

Background:

  • Frontal sinuses exhibit unique morphological characteristics.
  • These features can be valuable for individual identification, particularly in forensic contexts.
  • Understanding sex-based differences in frontal sinus morphology is important for accurate analysis.

Purpose of the Study:

  • To evaluate the morphological structure of frontal sinuses in Turkish adolescents.
  • To compare frontal sinus dimensions between male and female subjects.
  • To investigate correlations between frontal sinus measurements and other cephalometric parameters.

Main Methods:

  • Postero-anterior cephalometric radiographs of 148 Turkish adolescents (74 males, 74 females) were analyzed.
  • Measurements included frontal sinus height and width, maxillary width, nasal width, cranial width, and antegonial width.
  • Statistical analysis involved independent t-tests, Mann Whitney U tests, and Spearman correlation analyses.

Main Results:

  • Males showed significantly larger mean values for right and left frontal sinus width, maxillary width, antegonial width, and cranial width compared to females (P < 0.05).
  • Positive correlations were observed between right frontal sinus height and antegonial width in males (r=0.243; P<0.05).
  • Right and left frontal sinus width positively correlated with nasal width in females (r=0.244; P<0.05 and r=0.231; P<0.05, respectively).

Conclusions:

  • Frontal sinus morphology is highly individualized, offering potential for forensic identification.
  • Significant sex-based differences in frontal sinus dimensions were identified in the studied adolescent population.
  • Cephalometric analysis provides valuable data for understanding craniofacial development and forensic applications.
