概括

羊的椎运动范围 (ROM) 比人类更大,特别是在较低的水平和更高的扭矩时. 羊棘是特定的人类椎脊柱研究的可行替代品.

科学领域:

生物力学生物力学
脊柱研究脊柱研究
比较解剖学的比较解剖学

背景情况:

羊椎是脊柱植入体测试中人类标本的潜在替代品.
关于山羊椎脊柱的运动范围 (ROM) 的数据有限.
这项研究比较了新鲜的山羊和人类中椎脊柱样本的ROM.

研究的目的:

为了评估和比较新鲜的山羊和人类中椎脊柱标本的运动范围 (ROM).
在生物力学研究中确定山羊椎脊柱作为人类标本的替代品的适用性.

主要方法:

使用了十个新鲜的成年雄山羊和十个新鲜冷的成年人椎样本.
运动范围 (ROM) 在C2-3,C3-4,C4-5,C2-5级别在1.5Nm和2.5Nm扭矩下进行生物力学测试.
进行了统计分析 (独立样本t测试),以比较山羊和人类标本之间的ROM.

主要成果:

在C2-3,C3-4和C4-5级别 (除了1.5Nm的延伸外) 的山羊椎脊柱比人类脊柱显著更大的ROM.
在2.5Nm扭矩下,山羊脊柱在C2-3和C3-4级别的曲,横向曲和轴旋转方面显示出更大的ROM.
在两种扭矩条件下,与人类标本相比,山羊椎脊柱在C2-5级别的整体ROM显著更大.

结论:

测量了新鲜的山羊和人类椎样本的几个细分ROM.
可以推山羊宫标本作为人类标本的替代品,用于专注于C2-3,C3-4和C4-5ROM的 flexion (1.5Nm) 或 flexion and rotation (2.5Nm) 的特定研究.

Articulations of the Vertebral Column

Articulations of the Vertebral Column

In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

Spinal Cord: Cross-sectional Anatomy

Spinal Cord: Cross-sectional Anatomy

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.

Central to the gray matter is...

Overview of the Axial Skeleton

Overview of the Axial Skeleton

The skeleton is subdivided into two major divisions—the axial skeleton and the appendicular skeleton. The axial skeleton forms the vertical, central axis of the body. It includes all of the bones of the head, neck, chest, and back. It protects the brain, spinal cord, heart, and lungs. It also serves as the attachment site for muscles that move the head, neck, and back and for muscles that act across the shoulder and hip joints to move their corresponding limbs.
The axial skeleton of the...
