The primary function of the cerebrum is indeed related to movement and sensory input. The cerebrum is the largest part of the brain and is divided into two hemispheres, further subdivided into lobes that are responsible for various higher brain functions. It plays a crucial role in processing sensory information from various modalities, including sight, sound, and touch, allowing for perception, interpretation, and integration of sensory experiences.

Additionally, the cerebrum is integral to voluntary motor control, coordinating the planning and execution of movements. It contains areas involved in motor function, such as the motor cortex, which sends signals to the muscles to carry out intentional movements.

In summary, the cerebrum enables the integration of sensory data and the coordination of voluntary movements, making it essential for interaction with the environment, learning, reasoning, and decision-making. While muscular coordination, control of vital functions, and reflex actions are important neurological functions, they primarily involve other parts of the nervous system, such as the cerebellum for coordination and the brainstem for controlling vital functions and reflexes.
