Sensory conduction pathway refers to the pathway that passes through the peripheral nerves, spinal cord or brainstem, mesencephalon to the cerebral cortex after the nerve endings receive the stimulus, including proprioceptive, cutaneous sensory, visual and other conduction pathways. 1. Proprioceptive nerve conduction pathways. (1) Trunk and limb conscious proprioception and fine touch conduction pathway: Transmit proprioception and fine touch to the cerebral cortex to produce conscious sensation, which consists of 3 levels of neurons. (2) Trunk and limb non-conscious proprioceptive conduction pathway: transmits proprioception to the cerebellum, does not produce conscious sensation, and consists of level 2 neurons. (2) Cutaneous sensory conduction pathway: refers to pain and temperature sensation, coarse touch and pressure sensation conduction pathway, also known as superficial sensory conduction pathway, composed of level 3 neurons. It consists of level 3 neurons, including the skin sensation of the body and limbs, as well as the head and face nociceptive, warm and pressure sensory conduction pathways. 3. Visual conduction pathway: this pathway consists of 3 levels of neurons, the first level of neurons is the bi-level cells of the retina, the second level of neurons is the ganglion cells of the retina, and the cytosol of the third level of neurons is in the lateral geniculate body, and the axons emitted from them make up the optic radiation. Patients are advised to undergo treatment under the guidance of a medical professional to avoid adverse consequences.
