Question

Pars oralis

Option 1:
a) Rostral oropharynx

Option 2:
b) Caudal oral cavity

Option 3:
c) Rostral oral cavity

Option 4:
d) Caudal oropharynx

Answer 1

The term 'pars oralis' refers to the rostral (front) part of the oral cavity, which is contiguous with the oropharynx, making Option 3 the most appropriate answer.

Step-by-step explanation:

The term pars oralis likely refers to a part of the oral cavity. Since the oropharynx is a region of the pharynx that lies posteriorly to the oral cavity, providing a passageway for both air and food, the options provided relate to anatomical positioning within this area. Considering the definitions:

• Rostral generally refers to a structure closer to the front of the head.
• Caudal typically means a structure closer to the back or tail end.
• The oropharynx is bordered superiorly by the nasopharynx and is continuous with the oral cavity anteriorly.

Given this information, Option 3: c) Rostral oral cavity would be the most appropriate match for 'pars oralis,' indicating the front part of the oral cavity.
