Question

Quizplus · Accepted Answer

The medulla oblongata contains the corticospinal tracts, which control voluntary movements, the pyramids (bulges on the anterior surface), which are involved in motor control, and control centers for vital functions such as breathing, swallowing, and blood pressure regulation.

Answer: B
 The pons is involved in relaying information between different parts of the brain as well as between the brain and the spinal cord. It also contains centers for respiration, facial expressions, and sleep.

Answer: C
 The midbrain is involved in sensory and motor functions and contains nuclei that control eye movements and reflexes.

Answer: D
 The reticular formation is a network of neurons that run through the brainstem and is involved in regulating arousal, attention, and sleep. It also contains nuclei that regulate vital functions such as respiration and blood pressure.
