概括

猫的内动脉存在于胎儿和幼儿中,但由于自然消灭,在成年人中可能会失去其额外部段. 这一发现对于理解猫类大脑血液供应和兽医诊断至关重要.

科学领域:

兽医解剖学兽医解剖学
比较神经学比较神经学
发育生物学发展生物学

背景情况:

关于家猫内动脉的存在和范围,存在相互矛盾的文献.
一些研究报告它的缺席,而另一些研究则描述它是在大脑动脉系统内.

研究的目的:

在家猫的大脑动脉系统中调查内动脉的存在和发育变化.
为了澄清其在本体发生过程中大脑血液供应中的作用.

主要方法:

对61只家猫的分析,包括胎儿 (n=15),幼猫 (n=16) 和成年猫 (n=30).
详细检查不同年龄段的内动脉及其额外部段.

主要成果:

内动脉,一个具有显著流明的血管,在胎儿和大多数幼儿中一直被观察到.
在成人和一些青少年中,发现额外片被抹去,表明发育损失.
该研究确定了与年龄和消灭过程相关的内动脉完整性的变化.

结论:

在家猫中,内动脉的存在和完整性因年龄而异,特别是由于成年后其额外部段的消失.
对猫类大脑血管系统的精确解剖学知识对于解释诊断成像和进行手术干预至关重要.
这项研究有助于更清楚地了解猫神经血管系统,对生物和临床应用都有影响.

Arteries of the Head and Neck

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

The Arch of Aorta

The Arch of Aorta

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...
