The head

Even though it's not visible from the outside, the brain is the most important part of the head. It's a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body.

“The soul, fortunately, has an interpreter - often an unconscious but still a faithful interpreter - in the eye.”
― Charlotte Brontë, Jane Eyre

The human nose is the most protruding part of the face. It bears the nostrils and is the first organ of the respiratory system.
