Jake steps on a piece of ice with his right foot. Outline the pathway this sensation will travel to reach his brain being specific about the structures along the way
When Jake steps on a piece of ice it will activate a thermoreceptor which are free nerve endings in the dermis. This sensation will travel up the axon of a first-order neuron entering the CNS through the dorsal root. The first-order neuron will synapse with a second-order (interneuron) in the posterior gray horn. The second-order axons will enter the lateral spinothalamic tract on the opposite side of the spinal cord and ascend to the thalamus. At the thalamus the second-order neuron will synapse with a third-order neuron which will end at the primary sensory cortex on the left side of the brain.
