Answer:

1. The brain is located inside the bony covering called the cranium. The cranium protects the brain from injury.

2.  In terms of weight, the average adult human brain weighs in at 1300 to 1400 grams or around 3 pounds. In terms of length, the average brain is around 15 centimeters long. For comparison, a newborn human baby's brain weighs approximately 350 to 400 grams or three-quarters of a pound.

3. The brain controls what you think and feel, how you learn and remember, and the way you move and talk. But it also controls things you're less aware of — like the beating of your heart and the digestion of your food. Think of the brain as a central computer that controls all the body's functions.
