About: Neuraxis

An Entity of Type: anatomical structure, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The neuraxis or sometimes neuroaxis is the axis of the central nervous system. It denotes the direction in which the central nervous system lies. During embryological development, the neuraxis is bent by various flexures, contributing to the mature structure of the brain and spinal cord.

  • El neuroeje o, a veces, el neuroaxis o neuraxis​ es el eje del sistema nervioso central. Denota la dirección en la que se encuentra el sistema nervioso central. Durante el desarrollo embriológico, el neuroeje se dobla mediante diversas , lo que contribuye a la estructura madura del cerebro y la médula espinal. El desarrollo embrionario puede ayudar a comprender la estructura del cerebro adulto porque establece un marco sobre el que se pueden construir estructuras más complejas. Primero, el tubo neural establece la dimensión anteroposterior del sistema nervioso, que se denomina neuroeje. Se puede decir que el sistema nervioso embrionario de los mamíferos tiene una disposición estándar. Los humanos (y otros primates, hasta cierto punto) lo complican al ponerse de pie y caminar sobre dos piernas. La dimensión anteroposterior del neuroeje se superpone a la dimensión superior-inferior del cuerpo. Sin embargo, existe una curva importante entre el tronco encefálico y el prosencéfalo, que se denomina . Debido a esto, el neuroeje comienza en una posición inferior (el extremo de la médula espinal) y termina en una posición anterior, la parte frontal del cerebro. Esto puede resultar confuso y se puede ilustrar cuando se mira a un animal de cuatro patas de pie sobre dos patas. Sin la flexión en el tallo cerebral y en la parte superior del cuello, ese animal estaría mirando hacia arriba en lugar de hacia el frente.​ (es)
  • The neuraxis or sometimes neuroaxis is the axis of the central nervous system. It denotes the direction in which the central nervous system lies. During embryological development, the neuraxis is bent by various flexures, contributing to the mature structure of the brain and spinal cord. Embryonic development can help in understanding the structure of the adult brain because it establishes a framework on which more complex structures can be built. First, the neural tube establishes the anterior–posterior dimension of the nervous system, which is called the neuraxis. The embryonic nervous system in mammals can be said to have a standard arrangement. Humans (and other primates, to some degree) make this complicated by standing up and walking on two legs.The anterior–posterior dimension of the neuraxis overlays the superior–inferior dimension of the body. However, there is a major curve between the brain stem and forebrain, which is called the cephalic flexure. Because of this, the neuraxis starts in an inferior position—the end of the spinal cord—and ends in an anterior position, the front of the cerebrum. This may be confusing and can be illustrated when looking at a four-legged animal standing up on two legs. Without the flexure in the brain stem, and at the top of the neck, that animal would be looking straight up instead of straight in front. (en)

  • The mammalian nervous system is arranged with the neural tube running along an anterior to posterior axis, from nose to tail for a four-legged animal like a dog. Humans, as two-legged animals, have a bend in the neuraxis between the brain stem and the diencephalon, along with a bend in the neck, so that the eyes and the face are oriented forward. (en)
  • The embryonic brain develops complexity through enlargements of the neural tube called vesicles; The primary vesicle stage has three regions, and the secondary vesicle stage has five regions. (en)
