Question

Brain questions:

1. What are the three main parts of the brain?
2. What keeps the brain from being injured?
3. What is the large band of neural fibers connecting the two brain hemispheres and carries messages between them?

Answer 1

1. The brain can be divided into three basic units: the forebrain, the midbrain, and the hindbrain.

2. Three layers of membranes known as meninges protect the brain and spinal cord.

3. The two hemispheres are connected by a thick band of nerve fibres called the corpus callosum. The brain halves are able to communicate with each other via this bridge.
