Question

The chief function of semicircular canals is to

• A. Perceive changes in orientation of animal in relation to gravity
• B. Transmit sound vibrations
  
• C. Perceive sound vibrations
• D. None of the above

Answer 1

The correct option is A Perceive changes in orientation of animal in relation to gravity

• The vestibular apparatus in each ear includes the utricle, saccule, and three semicircular canals.
• Semicircular canals are three tiny, fluid-filled tubes in your inner ear that help you keep your balance.
• Animals that locomote must be able to adjust their orientation with respect to self-generated movements.
• The vestibular system helps in a number of reflex pathways that are responsible for making compensatory movements and adjustments in body position and also engages pathways that project the cortex to provide perceptions of gravity and movement.
• Hence, The chief function of semicircular canals is to Perceive changes in orientation of animal in relation to gravity.
• So, the correct answer is 'Perceive changes in orientation of animal in relation to gravity'.
