Which peripheral nerves are associated with the medulla?

The answer is based on the specific cranial nerves associated with the medulla oblongata, an essential part of the brainstem that plays a key role in autonomic and basic life functions. Cranial nerves IX (Glossopharyngeal) and X (Vagus) have their nuclei located in the medulla and are directly involved in vital functions, including cardiovascular and respiratory regulation. Additionally, cranial nerve VII (Facial nerve) also has connections through the medulla, particularly regarding its pathways.

Cranial nerve III (Oculomotor) is primarily associated with the midbrain, not the medulla. Therefore, the inclusion of cranial nerves VII, IX, and X, along with III in this context, highlights their functional importance and anatomical location that are relevant to the medulla's operations.

The remaining choices contain cranial nerves that do not have their nuclei within the medulla. For example, cranial nerves I and II (Olfactory and Optic) are associated with the forebrain, while cranial nerves V (Trigeminal) and VI (Abducens) are primarily linked with parts of the pons and midbrain respectively.
