Question

After drinking alcohol with friends, you find that you are having difficulty with simple coordination and movement. What proprioceptive sense has been affected:

a) Vestibular sense
b) Tactile sense
c) Auditory sense
d) Visual sense

Answer 1

The proprioceptive sense affected by alcohol, leading to difficulty with coordination and movement, is the vestibular sense, which is crucial for balance and posture.

Step-by-step explanation:

After drinking alcohol and experiencing difficulties with simple coordination and movement, the proprioceptive sense that has likely been affected is the vestibular sense. The vestibular sense contributes to our ability to maintain balance and body posture. It relies on the vestibular organs in the inner ear, which include the utricle, saccule, and the three semicircular canals, and these organs are responsible for sending information about movement and head position to the brain. When the cerebellum is compromised by alcohol, as alcohol affects the central nervous system, it impacts the cerebellum's ability to effectively coordinate movement and maintain balance, making tasks like walking straight challenging.
