The human brain is about 6 inches long, dark pink when healthy, and has the shape of a lopsided oval. It is covered in bumps.
The brain is a funny shape that is unexplainable to describe. Its kind of like a squiggy circle with bumps. Erm, if anyone has a better answer, be sure to edit.
make your hands into fists and bring them together so yr knuckles are touching, that's the shape and that's usually the size!
