Answer 1

Answer:

The neural pathway bringing temperature information from your left hand to the somatosensory cortex would have two synapses, with the first being in the spinal cord dorsal horn on the left side and the second being in the thalamus on the right side.

Explanation:

The stimuli received by the external receptors must travel from the place where they are produced to the association centers located in the central nervous system, where the information is processed.

In the case of the sensory nerves, which conduct the temperature-related information from the left hand, it happens that:

• They make their first synapse in the posterior horn of the spinal cord, responsible for receiving nerve impulses of sensitivity, on the same side as the stimulus (left).
• The second synapse occurs in the thalamus, an organ of the central nervous system that is responsible for receiving information related to temperature. As the sensory and motor pathways are crossed, the portion of the thalamus that receives the information is the right one.

One of the consequences of the crossing of the sensory pathways is that everything related to one side of the body is processed on the opposite side of the somatosensory cortex.
