解剖学上怎么解释猫追尾巴呢？
猫咪尾部的神经元活动，主要是由脊髓控制、按节段进行的反射性活动，基本形式是非条件反射。因此，猫咪的尾巴有时候看上去是和猫的行为脱节的，通俗来讲就是“没反应过来”。同时作为脊柱的最末端，猫的尾椎附近有丰富的神经。因此，尽管两者看似割裂，实际上尾巴却是猫体不可分割的重要部分！
那么究竟是什么让猫咪作出追尾巴这样神奇的举动呢？事实上分为两部分：一部分是正常的心理因素和兴趣爱好；而另一部分则是病理性因素，这需要我们广大铲屎官的注意了。
不同品种的猫，尾巴处骨头数量不同，大多数猫的尾椎骨数量为14~28块。猫的尾巴不仅可以感知温度，还可以感知气流变化。更为精妙的是，猫的尾巴可以很好地捕捉“震动信号”。
人的尾骨是人体脊柱的最末端,是人体进化过程中接近退化的一部分,呈三角形,一般来说由3~4块退化的尾椎融合而成。

In anatomical terms, how can we explain a cat chasing its tail? The neural activity in a cat's tail is primarily controlled by the spinal cord and consists of reflexive actions segmented by the spinal segments. It is essentially a form of non-conditioned reflex. Therefore, at times, the cat's tail movements may appear disconnected from its behavior, colloquially described as "not catching up." Additionally, as the furthest extension of the spine, the cat's tail has abundant nerve endings in the vicinity of the tail vertebrae. Hence, despite their seemingly separate nature, the tail is an integral and inseparable part of the cat's body.
So, what exactly triggers the fascinating behavior of a cat chasing its tail? It can be attributed to two factors: normal psychological factors and interests, as well as pathological factors that require the attention of cat owners.
Different cat breeds have varying numbers of bones in their tails, with most cats having between 14 to 28 caudal vertebrae. The cat's tail not only allows for temperature perception but also senses changes in airflow. Furthermore, the cat's tail is remarkably adept at capturing "vibrational signals."
In humans, the coccyx, or tailbone, is the most distal part of the vertebral column and represents a vestigial triangular structure formed by the fusion of three to four rudimentary coccygeal vertebrae during the evolutionary process.
