Pathways of the nervous system
Conscious sensory pathways are conductors, conducting nerve impulses to the cerebral cortex. Depending on the location of receptors may influence the nature of the impulses, conductive paths are divided into exteroceptive and proprioceptive. The first is responsible for joint and muscle sense, the second - for tactile, thermal and pain sensitivity. Conductors, closing below the bark, called afferent reflex pathways, such as cerebro-cerebellar reflex proprioceptive.
Motor ways, depending on the level of closure reflex arcs, which is the beginning of the path, fall into a conscious movement related to the pyramidal system and the beginning of the subcortical structures, and reflex motor or extrapyramidal. Names pathways are given in their place of finish. The specificity of motor reflex conditioned by the nature of conductors incoming pulses. Retikulospinnomozgovoy way ensures the maintenance of certain muscle tone. Krasnoyaderno-way lumbar control movement automated response. Tectospinal way responsible for reflex motor acts that occur in response to visual and auditory stimuli.
