STEM – The Human Brain

The brain. It is the most complex part of the human body. It is a soft mass of supportive tissues and nerves connected to the spinal cord. This three-pound organ is the seat of intelligence, interpreter of the senses, initiator of body movement, and controller of behavior and emotion. The brain is the source of all the qualities that define our humanity. It is the most precious and fascinating jewel of the human body.
