Alcohol
may positively affect the cardiovascular system of people over 50 years old by
reducing the risk of clot formation.
<span>Just like with the other body systems, excessive alcohol can have lethal
effects on the cardiovascular system. Chronic alcohol use can upsurge the
workload of the heart which can then lead to arrhythmia's or what is called an irregular
heart beat, inflammation of the heart muscle or myocarditis, weakening of the
heart muscle or cardiomyopathy, increased cholesterol, and even hypertension.

the heart that is linked to cirrhosis of the liver.</span>
A neurotransmitter can have an excitatory or inhibitory effect on the postsynaptic cell, depending on <u>which of its </u><u>receptor(s</u><u>) are present on the </u><u>postsynaptic</u><u> (target) cell.</u>
<h3>How do excitatory and inhibitory neurotransmitters act?</h3>
Sometimes neurotransmitters can bind to receptors and cause an electrical signal to be transmitted through the cell (excitatory). In other cases, the neurotransmitter can prevent the signal from continuing, preventing the message from being carried (inhibitory).
With this information, we can conclude that a neurotransmitter is a signaling molecule secreted by a neuron to affect another cell across a synapse.
