Step-by-step explanation:
The term for the part of the throat behind the mouth is oropharynx. It is a portion of the pharynx that is flanked by the nasopharynx, oral cavity, and laryngopharynx that functions as a passageway for both air and food. The oropharynx begins inferior to the nasopharynx and is continuous with the laryngopharynx below. Within the oropharynx are structures including the palatine tonsils, which are part of the body’s lymphatic system and are located anterior to the uvula at the roof of the isthmus of the fauces.
Detailed examination of the oropharynx is often part of a medical examination to check for infections like tonsillitis and to assess the function of cranial nerves associated with the oral cavity. The correct option is a. oropharynx
