Answer 1

Answer:

3 Main Parts of the 3 Pound Human Brain

Cerebrum

Cerebellum

Brain Stem

Explanation:

Cerebrum: also called cortex is by far the largest  portion of the brain, and weighs about two pounds. For the record, the entire  brain weighs three pounds. The cerebrum is home to billions and billions of  neurons. These neurons control virtually everything we do. It controls our  movements, thoughts and even our senses.

2. Cerebellum: from Latin “little brain”, the cerebellum is  a two-hemisphere structure located just below the rear part of the cerebrum,  right behind the brain stem. Representing about 11 percent of the brain’s  weight, it is a deeply folded and highly organized structure containing more  neurons than all of the rest of the brain put together. The surface area of the  entire cerebellum is about the same as that of one of the cerebral hemispheres.

3. Brain Stem: The brainstem is the smallest part of the  brain, sits beneath your cerebrum in front of your cerebellum, and it connects  the cerebrum to the spinal cord. Parts of the brainstem include: the midbrain,  medulla oblongata and the pons.
