Resumen

BARBER GUTIERREZ, Antonio et al. Axotomía vago-simpático cervical y degeneración nerviosa intrapulmonar en ratas. Rev Cubana Invest Bioméd [online]. 2001, vol.20, n.2, pp.104-112. ISSN 0864-0300.

The axotomy of a peripheral nerve leads to the interruption of the continuity of the axon with wallerian degeneration in the distal segment of the neuron. The posttraumatic process of the nerve injures the axon and its sheath of myelin and the damaged material is invaded by haematogenous phagocytes that with the course of time remove most of the myelin fibers and other endoneural cells. This fact allowed to follow the nervous intrapulmonary pathway after the section of the vagosympathetic cervical trunk in the rat, due to the appearance in the degenerative process of products of the desintegration of lipids from myelin, stained with Sudan III and IV. The aim of this paper was to show the pathway of the autonomic intrapulmonary fibers and their relationship with the thinnest divisions of the respiratory bronchi, taking into account the function of the autonomic nervous system in bronchial asthma
