概括
与健康儿童相比,患有脑膜髓炎 (MMC) 的儿童的脊髓硬. 这种增加的脊髓硬性也与MMC的婴儿的脑水症有关.
科学领域:
- 儿科神经学 儿科神经学
- 医疗成像医学成像
- 生物机械工程 生物机械工程
背景情况:
- 脑膜炎 (MMC) 是一种复杂的先天性疾病,影响脊髓发育.
- 在患有MMC的婴儿中评估脊髓生物力学对于了解疾病进展和潜在干预措施至关重要.
- 剪波弹性学 (SWE) 提供了一种非侵入性方法来评估组织弹性.
研究的目的:
- 通过剪波弹性学 (SWE) 来量化脑膜细胞 (MMC) 的婴儿的脊髓弹性.
- 为了比较患有MMC和健康对照的婴儿之间的脊髓弹性.
- 研究MMC.婴儿脊髓弹性,神经缺陷和水头症之间的相关性.
主要方法:
- 一项前性研究,涉及70名患有MMC的婴儿 (未满6个月) 和50名年龄相匹配的健康对照.
- 剪切波弹性图 (SWE) 在D10-D12水平上测量脊髓 (dura mater, arachnoid mater, pia mater,中央通道).
- 大脑超声波以评估脑水性;统计分析以α=0.05.5的显著性水平进行.
主要成果:
- 与对照组相比,患有MMC的婴儿在所有测量层中表现出显著更高的脊髓弹性值 (p < 0.001).
- 在有或没有神经缺陷的情况下,在弹性方面没有发现显著差异.
- 脊髓弹性,特别是在硬骨质中,与没有MMC和脑水相比,MMC和脑水的婴儿显著更高 (p < 0.001).
结论:
- 患有脑膜叶瘤 (MMC) 的婴儿明显比健康婴儿有更硬的脊髓.
- 患有MMC的婴儿脊髓弹性升高与水脑的存在有关.
- SWE是评估脊髓生物力学特性的宝贵工具,用于儿童神经疾病,如MMC.

01:54The Spinal Cord
32.7K
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.

01:16Spinal Cord: Cross-sectional Anatomy
5.9K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

The spinal cord, a critical component of the central nervous system, extends from the base of the brainstem to the lumbar region of the vertebral column. It is essential for maintaining physical stability and facilitating communication between the brain and peripheral parts of the body.

01:19Cranial and Spinal Meninges
4.7K
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...

The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...
