Head

The head is the uppermost part of a humanoid, it contains the brain, skull, eyes, ears, nose and mouth.

Cranial lobes, the enlarged foreheads of species such as the Malcorians, are also part of the head. Dr. Berel once stated to 'Rivas Jakara', Commander William T. Riker in disguise, that "your cranial lobes, for instance seem to be surgical implants". Where Rivas replied that he had genetic irregularities. 

Data's head was once left in the past under the city of San Francisco for more than 500 years. .
