- 人类横向性研究研究人类横向性研究.
- 牙科生物力学 牙科生物力学
背景情况:
- 在牙科和生理学研究中,了解影响首选侧面 (PCS) 的因素至关重要.
- 以前的假设表明PCS和半球体横向性 (HBL) 之间存在联系,但这需要经验验证.
- 牙状况在确定PCS中的作用尚未完全阐明.
研究的目的:
- 为了研究一个人喜欢的侧面 (PCS) 和他们的半球体侧面 (HBL) 之间的相关性.
- 要确定牙状态,特别是剩余牙的数量,是否会影响首选的侧.
- 分析与HBL和牙状况有关的咬伤力不对称性,闭合接触区域和PCS之间的关系.
主要方法:
- 82名志愿者参与了这项研究.
- 使用专用牙科设备评估咬伤力 (ABF) 和闭合接触区域 (OCA) 的不对称性.
- 通过不对称指数 (ASI) 和视觉模拟尺度 (VAS) 评估首选的侧面 (PCS),以及半球体横向性 (HBL) 测试 (手性,脚性,耳性,眼性).
主要成果:
- 半球体横向性测试 (手,眼睛,耳朵) 显示出实质性的可重复性,而脚的横向性显示出中等的一致性.
- 在偏好的侧面 (PCS) 和半球体侧面 (HBL) 之间没有发现显著的相关性,除了耳朵侧面和VAS之间的弱相关性.

Teeth
361
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...

Lateralization
317
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.

Cranial Nerves: Types Part I
2.1K
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...

Psychosexual Stages of Personality: Oral
611
The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.
