**Core Concept**
The external auditory canal, also known as the ear canal, is a narrow passageway that connects the outer ear to the eardrum. It is composed of cartilage and skin, providing protection and facilitating sound conduction.

**Why the Correct Answer is Right**
The cartilaginous part of the external auditory canal is located anteriorly, while the bony part is located posteriorly. The cartilage provides flexibility and allows for the canal to move with the pinna, while the bony part provides additional protection and support. The cartilaginous part is also less dense and more pliable than the bony part.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because the cartilaginous part is not located laterally.
**Option B:** Incorrect because the cartilaginous part is not located medially.
**Option C:** Incorrect because the cartilaginous part is not located superiorly.

**Clinical Pearl / High-Yield Fact**
The external auditory canal is an important landmark in otoscopy and tympanocentesis, and its anatomy is crucial for understanding various ear conditions and performing procedures.

**Correct Answer: C. The cartilaginous part of the external auditory canal is located anteriorly.**
