Verified step by step guidance1
Understand the role of the medulla oblongata: The medulla oblongata is a part of the brainstem that plays a crucial role in autonomic functions, which are involuntary and essential for survival.
Identify the functions typically associated with the medulla oblongata: These include regulation of heart rate, blood pressure, breathing, and reflexes such as swallowing and vomiting.
Evaluate each option: Consider whether each function listed is an autonomic function or involves involuntary control.
Regulation of heart rate: This is an autonomic function and is controlled by the medulla oblongata.
Processing visual information, voluntary muscle movement, and memory formation: These functions are not primarily controlled by the medulla oblongata. Visual processing is mainly handled by the occipital lobe, voluntary muscle movement by the motor cortex, and memory formation by the hippocampus.
