The brain

AQA GCSE Biology revision on The brain. Aligned to the AQA GCSE Biology 8461 specification. This bank has 25 practice questions on this topic.

Sample questions (3 of 25)

Question 1

Which specific region of the brain is primarily responsible for coordinating balance and muscle activity?
- A) The medulla oblongata
- B) The cerebellum
- C) The cerebral cortex
- D) The pituitary gland
Show answer

Answer: The cerebellum

The cerebellum is located at the back of the brain and is essential for coordinating muscular activity and maintaining posture. While the cerebral cortex handles complex conscious thought, the cerebellum functions automatically to ensure smooth physical movement and balance.
Question 2

What is the primary function of the medulla oblongata within the human brain?
- A) Regulating heart rate
- B) Controlling body temperature
- C) Managing conscious thought
- D) Storing long-term memory
Show answer

Answer: Regulating heart rate

The medulla oblongata is situated at the base of the brain stem. It is responsible for controlling unconscious, life-sustaining functions such as the heart rate and the rate of breathing without conscious effort.
Question 3

Which major part of the brain is responsible for complex functions such as memory, language, and consciousness?
- A) The frontal cerebellum
- B) The cerebral cortex
- C) The spinal cord base
- D) The hypothalamus
Show answer

Answer: The cerebral cortex

The cerebral cortex is the highly folded outer layer of the brain. It is the site of complex cognitive processes, including intelligence, language, memory, and conscious thought, distinguishing humans from many other animals.
