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 View01:14

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,...

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...

Cranial and Spinal Meninges01:19

Cranial and Spinal Meninges

4.5K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Lobes of the Cerebrum01:22

Lobes of the Cerebrum

5.1K
The cerebral cortex, a critical structure of the brain, is intricately divided into two hemispheres, each consisting of four distinct lobes: occipital, temporal, frontal, and parietal. These lobes function cooperatively to regulate various cognitive and sensory functions, forming the basis of our complex neural capabilities.
Frontal lobe
The frontal lobes, located behind the forehead, are the command center of our brain, controlling personality, intelligence, and voluntary muscle movements....

Lateralization01:28

Lateralization

1.1K
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Summary
This summary is machine-generated.

Ponticulus posticus, an anomaly of the first cervical vertebra, affects over a third of Nepalese orthodontic patients. Early detection via lateral cephalograms is crucial due to its medical and surgical implications.

Area of Science:

  • Orthodontics
  • Radiology
  • Anatomy

Background:

  • Ponticulus posticus is a common anomaly of the first cervical vertebra.
  • This condition often goes undetected by orthodontists, despite its medical and surgical significance.

Purpose of the Study:

  • To determine the prevalence of ponticulus posticus in Nepalese orthodontic patients.
  • To raise orthodontists' awareness of this vertebral anomaly.

Main Methods:

  • A retrospective analysis of 414 digital lateral cephalograms from orthodontic patients.
  • Two independent investigators assessed the cephalograms for the presence of ponticulus posticus.

Main Results:

  • Ponticulus posticus was identified in 35.7% of the patients.
  • Partial ponticulus posticus occurred in 30.9% and complete ponticulus posticus in 4.8% of cases.
  • No statistically significant gender association was found.

Conclusions:

  • Ponticulus posticus is a prevalent anomaly in Nepalese orthodontic patients, affecting over one-third.
  • The anomaly's prevalence is independent of gender.
  • Orthodontists should utilize lateral cephalograms for screening due to associated medical and surgical implications.
