Question 1: Define the term 'cerebrum' and explain its primary function in the brain.

Answer: The cerebrum is the largest part of the brain responsible for higher brain functions such as thought, memory, and voluntary movement.

Question 2: Which part of the brain controls balance and coordination? A) Cerebrum B) Cerebellum C) Brainstem D) Hypothalamus

Answer: B) Cerebellum

Question 3: Fill in the blank: The __________ is responsible for regulating vital functions such as breathing and heart rate.

Answer: brainstem

Question 4: Describe the process by which the brain receives and processes sensory information.

Answer: Sensory receptors detect stimuli and send signals through neurons to the brain. The brain then interprets these signals to perceive sensations and respond accordingly.

Question 5: Calculate the total weight of the brain if the cerebrum weighs approximately 1.4 kg, the cerebellum weighs 150 g, and the brainstem weighs 100 g. Use the formula: Total weight = Sum of individual parts. Express your answer in grams.

Answer: Total weight = 1400 + 150 + 100 = 1650 grams

Question 6: In an experiment, students observe that damage to the hippocampus impairs memory formation. Which part of the brain is affected?

Answer: B) Hippocampus

Question 7: Explain how the brain maintains homeostasis in the body. Include at least two mechanisms or processes involved.

Answer: The brain maintains homeostasis through mechanisms such as regulating body temperature via the hypothalamus and controlling water balance through the release of hormones. It constantly monitors internal conditions and initiates responses to keep the body's environment stable.

Question 8: Identify which part of the brain is primarily involved in processing visual information.

Answer: The occipital lobe.

Question 9: Discuss one practical application of understanding brain structure in medicine or technology.

Answer: Understanding brain structure helps in diagnosing and treating neurological disorders such as Parkinson's disease, and it aids in developing brain-computer interfaces that can assist individuals with paralysis or other disabilities.
