概括
在前额头上部区域的膜底 (MAB) 不仅仅位于膜下部 (MS). 这一解剖学发现对于外科手术和牙科教育至关重要.
科学领域:
- 人体解剖学 解剖学 解剖学
- 口腔和牙面部外科手术
- 放射学 放射学是一门学科.
背景情况:
- 上部后牙通常被认为仅位于上鼻腔 (MS) 下方.
- 大气泡底 (MAB) 与鼻腔之间的解剖关系需要进一步研究.
- 一个假设表明,前额头上部区域的MAB并非完全低于MS.
研究的目的:
- 为了研究上前区域的膜底 (MAB) 的解剖关系.
- 为了确定MAB是否仅限于鼻腔,或者它是否也与鼻腔有关.
- 为了记录MAB的上层关系,如鼻腔,鼻腔或两者兼而有之.
主要方法:
- 分析了145个圆束计算机断层扫描 (CBCT) 扫描.
- 大气泡底部 (MAB) 的分类有四种类型:腹腔,腹腔与口腔隙,腹腔和鼻腔,鼻腔.
- 对2型和3型MAB配置的特定尺寸的测量.
主要成果:
- 膜底 (MAB) 在67.24%被归类为1型 (口腔),在13.45%被归类为2型 (口腔与 palatal recess),在16.21%被归类为3型 (口腔和鼻腔),在3.1%被归类为4型 (鼻腔).
- 在右大鼻的11.72%和左大鼻的15.17%观察到宫内.

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...

01:27Cranial Bones: Lateral View
2.2K
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...

01:15Teeth

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

01:29Bone Formation by Intramembranous Ossification
6.0K
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...

01:08Overview of the Skull
4.5K
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...
