Question

Quizplus · Accepted Answer

The medulla is the most caudal (lowest) portion of the brainstem and sits just above the cervical spine. It is responsible for vital bodily functions such as regulating heart rate, breathing, and blood pressure. The cerebellum sits above the medulla, but it is not the most caudal portion of the brain. The pons is located above the medulla but is not the most caudal portion. The reticular formation is a network of neurons that runs the length of the brainstem and is not a specific structure located in the caudal portion of the brain.
