Verified step by step guidance
1
Identify the location and function of the cerebrum in the brain. The cerebrum is the largest part of the brain, located in the upper part of the cranial cavity.
Understand the primary functions of the cerebrum. It is responsible for higher brain functions, including voluntary motor activity, sensory perception, and cognitive abilities such as thinking, reasoning, and memory.
Differentiate the cerebrum from other parts of the brain. The brainstem, for example, is involved in basic life functions like heart rate and breathing, while the cerebellum is involved in balance and coordination.
Evaluate the statements given in the problem. The first statement incorrectly associates the cerebrum with the brainstem and reflex actions. The second statement incorrectly describes the cerebrum as the smallest part of the brain. The third statement incorrectly attributes heart rate and breathing regulation to the cerebrum.
Conclude that the correct statement is that the cerebrum is responsible for voluntary motor functions and cognitive abilities, aligning with its known functions and characteristics.
