Final answer:
The dorsal surface of the pons does not feature prominently named bulges as suggested by the options provided. The pons is characterized by a surface of white matter and is known to connect the hindbrain to the rest of the brain.
Step-by-step explanation:
The prominent bulges on the dorsal surface of the pons are not specifically named in the choices provided. However, when referring to the surface of the brain and the brainstem, the term gyri is used to describe the bumps or folds, and sulci refers to the grooves. In the case of the pons, visible on the anterior surface, the thick bundle of white matter that connects to the cerebellum is a distinctive feature, but it is not typically referred to as a sulcus or a gyrus. The pons serves to connect the hindbrain to the rest of the brain and is involved in regulating brain activity during sleep. If by 'pons bulges' the question is referencing the external anatomy, this would be better described as the pontine surface, rather than a specific sulcus or gyrus.
