function:Two pont discrimination, vibration and proprioception
Spinothalamic tract Location, first order neuron, second order neuron function
location: Anterior spinal cord
first order neuron:orignates in dorsal root ganglion, synapse in dorsolateral tract of lissauer

function: senses pain and temp
corticospinal tract Location, first order neuron, second order neuron function
location: lateral spinal cord
first order neuron: descends from internal capsule and mid brain, decussates in medullary pyramids, descends in corticospinal tract, synapse in ventral horn through interneurons
