If I Only Had a Brain!
Ain't Knowledge Fun?
The adult human brain normally weighs from 2¼ to 3¼ pounds. Differences in weight and size do not correlate with differences in mental ability.
Anatomically, the brain has three major parts: the hindbrain, which includes the cerebellum and the brain stem and controls major muscle movements and involuntary activities such as breathing; the midbrain; and the forebrain, which includes the cerebrum, occupying the topmost portion of the skull and by far the largest sector of the brain. It contains most of the master controls of the body and is also the center of learning, reason and memory.
The human brain consists of some 10 billion interconnected nerve cells, each with innumerable extensions. This interlacing of nerve fibers and their junctions allows a nerve impulse to follow any of a virtually unlimited number of pathways, the effect being to give humans a seemingly infinite variety of responses to sensory input. Imagine what your business or organization would be like if you could do that!
