The ceruminous glands are found in the ______ of the external auditory canal. A) Outer 1/3 B) Inner 2/3

Understand the Problem

The question is asking for the specific location of ceruminous glands in the external auditory canal, specifically whether they are located in the outer third or the inner two thirds.

More Information

Ceruminous glands are responsible for producing cerumen, commonly known as earwax, which acts as a protective barrier in the outer ear against dust, microorganisms, and other foreign particles.

Tips

A common mistake is confusing the location of the ceruminous glands with that of the entire ear canal, not realizing they are specifically in the outer portion.
