Answer #1

The auditory nerve carries the auditory impulses from the ear to the auditory cortex.
The auditory arises from the bipolar cells of the cochlea. The nerve then ascends to the brainstem and makes the first synapse at the cochlear nuclei of the same side. After that the nerve crosses the midline and synapses with superior olivary complex of the other side. Then the nerve travels to the inferior colliculus and then to the medial geniculate body of thalamus. From thalamus the nerve passes to the auditory cortex where the processing of impulse occurs.
The auditory nerve makes connection to the cochlear nucleus of the same side. Therefore left auditory nerve will make connections with left cochlear nucleus.

Do left-handed people live shorter lives than right-handed people? A study of this question examined a sample of 949 death records and contacted next of kin to determine handedness. Note that there are many possible definitions of "left-handed." The researchers examined the effects of different definitions on the results of their analysis and found that their conclusions were not sensitive to the exact definition used. For the results presented here, people were defined to be right-handed if they wrote, drew,...
