Nerve05/disorders of the spinal cord and optic pathway/ascending pathway of deep and touch sensationのソースを表示

For deep sensation from joints and muscles and skin touch/pressure sensation, the pathway enters the spinal cord from the posterior root, and does not synapse immediately afterwards; rather the first sensory neuron fiber ascends the posterior column-medial lemniscus pathway of the same side of the spinal cord to the medulla oblongata, where it synapses and the second neuron crosses to the other side.
