Explanations: answer key for all 10 questions

Q1: About how much does an adult human brain weigh?
Answer: About 1.4 kilograms
It makes up about 2% of body weight.
Q2: About how much of the body's energy does the brain use?
Answer: About 20%
It is very energy hungry.
Q3: Which is the largest part of the brain?
Answer: Cerebrum
It handles thinking, senses and movement.
Q4: Which part of the brain coordinates balance and movement?
Answer: Cerebellum
It is at the back, under the cerebrum.
Q5: Which part controls breathing and heartbeat?
Answer: Brainstem
It connects the brain to the spinal cord.
Q6: Which lobe processes vision?
Answer: Occipital lobe
It is at the back of the head.
Q7: Which seahorse-shaped structure is key for forming memories?
Answer: Hippocampus
Its name comes from the Greek for seahorse.
Q8: About how many neurons are in the human brain?
Answer: About 86 billion
Each can connect to thousands of others.
Q9: The left hemisphere mostly controls which side of the body?
Answer: The right side
Nerve pathways cross over.
Q10: Which area of the brain is linked to producing speech?
Answer: Broca's area
Paul Broca described it in 1861.

Brain Anatomy Quiz – The Control Center

The brain controls thoughts, feelings, memories, senses and movements. It weighs about 1.4 kilograms but uses roughly a fifth of the body's energy. It is made of about 86 billion neurons connected by trillions of synapses.

The brain has three main parts. The cerebrum handles thinking and senses and is divided into frontal, parietal, temporal and occipital lobes. The cerebellum coordinates balance and movement, and the brainstem controls breathing, heartbeat and sleep.

Scientists study the brain using imaging like MRI and EEG. The brain can change and form new connections throughout life, a property called neuroplasticity, which helps people learn and recover after injury. Sleep, exercise and learning all support brain health.
