Question

multiple choice question

which ducts of the inner ear are specialized to detect rotational head movements (angular acceleration)?

apical
cochlear
semicircular
tubular

Explanation:

Identify the function of semicircular ducts

Using the Semicircular Ducts and Dynamic Equilibrium knowledge points
The semicircular ducts of the inner ear contain sensory receptors (cristae ampullares) that detect rotational movements of the head, also known as angular acceleration.

Evaluate the incorrect options

Using the Inner Ear Anatomy knowledge point

• Apical: Refers to the apex or tip of a structure (such as the cochlea) and is not a type of duct.
• Cochlear: The cochlear duct is involved in hearing, not equilibrium.
• Tubular: This is a general anatomical shape descriptor and does not refer to a specific functional duct of the inner ear.

Answer:

• Apical
• Cochlear
• Semicircular (Correct answer)
• Tubular
