What is the name of the small, rounded, fleshy bulge located just anterior to the ear canal?

• A. Incus
• B. Pinna
• C. Stapes
• D. Tragus

Answer: (D)

The correct term for the small, rounded, fleshy bulge located just anterior to the ear canal is the tragus. The tragus is a part of the outer ear, specifically the cartilage structure that protrudes at the front of the ear, serving as a protective barrier for the ear canal. It plays a role in directing sound waves into the ear canal and can also help protect the ear from foreign objects or debris. The other options refer to different structures related to the ear or auditory system. The incus and stapes are both small bones located in the middle ear, involved in the transmission of sound vibrations. The pinna, on the other hand, refers to the entire outer ear structure, which encompasses the tragus as well. Thus, while other choices are integral parts of the auditory system, the tragus specifically identifies the fleshy bulge directly in front of the ear canal.
