马的胸部脊柱病理因品种而异. 温血马患有更多的骨关节炎,而科尼克马患有较高的椎间盘矿化,夏特兰小马经常表现出关节过程关节无形成症.
科学领域:
- 马类兽医药 马类兽医药
- 比较病理学比较病理学
- 放射学 放射学是一门学科.
背景情况:
- 有限的数据存在于非 Thoroughbred 品种的马胸部病理.
- 了解特定品种的脊柱状况对于马的健康至关重要.
研究的目的:
- 记录和比较温血马,雪特兰小马和科尼克马的胸椎脊柱的骨性病理变化.
- 评估这些品种中特定病理的患病率和严重程度.
主要方法:
- 一个描述性的死后研究,利用计算机断层扫描 (CT) 的胸脊柱.
- 对34匹温血马,28匹夏特兰小马和18匹科尼克马进行了检查.
- 骨关节炎 (OA) 的评分,周关节骨质溶解,骨囊状病变,关节过程关节 (APJ) 碎片, costovertebral 和 costotransverse 关节变化,软组织矿化,脊椎间盘 (IVD) 矿化,脊椎过程 (SP) 冲击和脊椎病.
主要成果:
- 在夏特兰小马 (98%) 中,APJ无形成症的发病率很高.
- 温血马显示OA (45%) 和SP (11.2%) 的患病率最高.
- 科尼克马表现出最高的IVD矿化 (20%),随着年龄的增长而增加,以及显著的软组织矿化.
结论:
- 在胸椎脊柱病理方面发现了显著的品种特异性差异.
- 在所有品种中,Costotransverse关节病理比APJ病理更常见.
- 热血动物易患OA和SP冲击,Konik易患IVD矿化,Shetland易患APJ无形成症,Shetland的其他病态发生率通常较低.

Vertebral Column: Regions and Curvature
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Muscles of the Vertebral Column
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...
