Alcohol relaxes the fine muscles of the eyes which focus and control eye movement
Alcohol is a depressant, which means that it slows down the function of the central nervous system by slowing down the transmission of signals between neurons in the central nervous system, specifically in the cerebellum. These effects can lead to impaired vision, reduced depth perception, and decreased ability to focus on objects
Alcohol relaxes the fine muscles of the eyes, affecting focus and eye movement. Additionally, alcohol inhibits ADH release, leading to increased urine output (option c).
Alcohol consumption affects various bodily functions, including the nervous system and the control of fine motor skills. Specifically regarding the fine muscles of the eyes which are responsible for focusing and controlling eye movement, alcohol actually relaxes these muscles (option c). This relaxation can lead to blurred vision and difficulty in focusing, a common symptom of intoxication. Furthermore, alcohol's effects on the nervous system are considerable, leading to potential issues with circulation, temporary changes in mental state, and weakened cognitive functions.
When it comes to the endocrine system, alcohol consumption leads to an increase in urine output, primarily because it inhibits ADH (antidiuretic hormone) release. ADH is crucial for water reabsorption in the kidneys, and when its release is inhibited, less water is reabsorbed, which results in increased urine production.
