まとめ
この研究では,頭蓋骨の41%で,頭蓋骨後穴 (PGF) を含む頭蓋骨の穴を特定しました. これらの解剖学的変異に対して新しい分類体系が提案され,手術計画と放射線学的解釈を助長した.
科学分野:
- アナトミー
- 人類学
- 放射線科
背景:
- ポストグレノイド穴 (PGF) は,骨の珍しい解剖学的変形である.
- PGFの形態学,流行,および臨床的意義に関するデータは限られているが,特に非ヨーロッパ人群では限られている.
研究 の 目的:
- PGFを含む状骨の解剖学と頻度を調べる
- 解剖学的な位置に基づいたこれらの穴の分類システムを提案する.
主な方法:
- 117 人の頭蓋骨 (234 面) の検査は,粗略な観察と死体解剖を用いて行われました.
- 選択された症例のコンピュータートモグラフィー (CT) スキャンは,頭蓋骨の溝の伝達を確認します.
- ポストグレノイドプロセス (PGP) と骨のアーチに対するフォアミナの位置づけと分類.
主要な成果:
- フォラミナは41. 0%の頭蓋骨 (28. 6%の側面) で特定され,左-右の有意な差異はありませんでした.
- 3種類のフォアミナを分類した. プレグレノイド (76. 7%),ポストグレノイド (6. 8%) とスプラアークュエート (16. 4%).
- 3つのフォアミナが 中間頭蓋骨と繋がっていることが CTで確認された.
結論:
- 側頭骨のフォラミナ (PGF) を含む,実践的な分類システムが確立されています.
- 発見は手術計画と放射線学的解釈に臨床的に関連しており,感染や静脈伝達の可能性を強調しています.
- これらのホルモンの組織学的構造と発達の起源に関するさらなる研究が推奨されます.

Cranial Bones: Lateral View
2.6K
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...

Anatomy of the Brain: Ventricles
5.1K
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen.

Cranial Bones: Superior and Posterior View
2.8K
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,...

Anatomy of the Ear
8.8K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Bone Markings
6.1K
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

Sutures of the Skull
7.6K
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...
