Answer:
the midbrain (mesencephalon), the pons (metencephalon), and the medulla oblongata (myelencephalon)
Midbrain, also called mesencephalon, region of the developing vertebrate brain that is composed of the tectum and tegmentum.
pons: Contains nuclei that relay signals from the forebrain to the cerebellum, along with nuclei that deal primarily with sleep, respiration, swallowing, bladder control, hearing, equilibrium, taste, eye movement, facial expressions, facial sensation, and postures
The medulla oblongata plays a critical role in transmitting signals between the spinal cord and the higher parts of the brain and in controlling autonomic activities, such as heartbeat and respiration.
