When you close your eyes and raise your hand above your head, you know where your hand is because of

• A. the vestibular sense.
• B. the kinesthetic sense.
• C. your otolith organs.
• D. your semicircular canals.

Answer: (B)

Verified step by step guidance

1. Understand the concept of kinesthetic sense: It refers to the ability to sense the position and movement of our body parts, even without visual input.
2. Differentiate between kinesthetic sense and vestibular sense: The vestibular sense is related to balance and spatial orientation, primarily involving the inner ear structures.
3. Identify the role of otolith organs: These are part of the vestibular system and help detect linear accelerations and head position relative to gravity.
4. Recognize the function of semicircular canals: These are also part of the vestibular system and are responsible for detecting rotational movements.
5. Conclude that knowing the position of your hand without looking is primarily due to the kinesthetic sense, which involves proprioceptors in muscles and joints providing feedback about limb position.
