The structure that forms cranial nerve I is the olfactory nerves while forming the 2nd is the optic nerve. Together with retina and olfactory epithelium, all of them are considered part of the Central Nervous System — wherein they synapse directly to the brain without the aid of any ganglia.
Answer:for number 1. it’s 1) flexibility
Explanation:
Alcohol acts as a depressant and slows nerve responses and depresses the central nervous system.
Excessive drinking over a prolonged period of time can cause serious problems with cognition and memory.
Alcohol interacts with the brain receptors, interfering with the communication between nerve cells, and suppressing excitatory nerve pathway activity.
Neuro-cognitive deficits, neuronal injury, and neurodegeneration are well documented in examples of alcoholics, yet the underlying mechanisms remain elusive. The effect can be both direct and/ or indirect.
The inner ear and cerebellum are areas of the brain involved in coordination and balance. These can be affected by alcohol producing difficulty with walking, hand-eye coordination and reaction time.
Impaired judgment, slowed reaction time, impaired vision and alertness, decreased coordination, confusion, loss of balance
