Final answer:
The cerebrum controls conscious thought processes, intellectual functions, memory storage and processing, and conscious and subconscious control of skeletal muscle movements. It consists of two hemispheres, four lobes, and is responsible for complex functions like reasoning and language.
Step-by-step explanation:
The cerebrum plays a pivotal role in various high-level brain functions in mammals. It is the largest part of the brain, encompassing the cerebral cortex and several deep nuclei. The primary function of the cerebrum is associated with conscious thought processes, intellectual functions, memory storage and processing, and the conscious and subconscious control of skeletal muscle, which correlates with option 4 from the student's initial list. This includes reasoning, language, sight, touch, hearing, and voluntary movements. The cerebrum is divided into two hemispheres, connected by a bundle of axons, and further into four lobes: frontal, parietal, temporal, and occipital. Each of these lobes is responsible for processing different types of sensory information, but they also work together to perform complex functions. For example, language involves areas in both the temporal and frontal lobes, showcasing the interconnectedness of cerebral functions. Additionally, the cerebellum, often confused with the cerebrum, coordinates somatic motor patterns (option 2), while the brainstem, which includes the medulla oblongata and pons, is crucial for autonomic functions such as breathing and heart rate control.
