Body coordination can be disrupted by various factors, with the uncontrolled consumption of drugs and alcohol being a major cause. Drugs are chemical substances that disrupt neuron function by delaying or altering impulse transmission.
Four drug categories act on the nervous system in different ways.
Drugs are chemical substances that can disrupt neuron function by delaying impulse transmission in the neuron. Drugs taken without control disrupt body coordination and cause addiction.
Some drugs are used as medicine, such as morphine and steroids, but they must be taken under a doctor's supervision. Uncontrolled use leads to addiction, physical harm, and impaired mental and physiological coordination.
Depressants slow down impulse transmission, stimulants speed it up, inhalants are inhaled chemicals that damage vital organs, and hallucinogens alter impulse pathways in the brain.
Uncontrolled drug consumption leads to addiction. When addicts stop taking drugs, they experience withdrawal symptoms such as shivering, nausea, anxiety and depression.
Curiosity, peer influence, seeking pleasure, and the desire to overcome sadness or forget a problem.
Drugs can stimulate the nervous system, slow it down, or disrupt it, causing changes in heartbeat, breathing rate, blood pressure, perception and behaviour.
Drug and alcohol abuse disrupts four important coordination functions.
Chronic abuse causes permanent damage to organs and behaviour.
Continuous excessive alcohol consumption and drug abuse cause toxic effects on the liver. The liver undergoes chronic damage, scarring, hardening and failure to function normally. The scar spreads until liver function is completely lost.
Excessive alcohol stimulates the stomach to produce more acid than normal, causing irritation and inflammation of the stomach lining. Symptoms include heartburn, pain in the upper liver region, bloatedness, nausea, vomiting, vomiting blood and passing out black stools.
Drugs like amphetamine activate brain cells and raise metabolism, making the user sleepless, active, violent and aggressive. Excessive alcohol makes a person lose senses, act out of control, laugh alone and turn violent.
Drugs like marijuana disrupt brain function and alter perception. This causes hallucination, paranoia, suspicious feelings, fear of others and aggressive behaviour.

What is the effect of depressant drugs on impulse transmission in body coordination?
How does ethanol in alcohol cause slow reflex actions in an individual?
Name two symptoms of stomach ulcers caused by excessive alcohol consumption.
All drugs are illegal and inherently harmful substances.
Some drugs are essential medicines, such as morphine for pain relief and steroids, when taken under strict medical supervision. Harm occurs when they are abused or taken without control.
Alcohol is a stimulant because it can cause loud or aggressive behaviour.
Alcohol is a depressant. It slows down the central nervous system and the flow of nerve impulses, and impairs the cerebrum, which results in loss of self-control and slurred speech.
1 Which of the following drugs speeds up impulse transmission in body coordination, causing the user to feel alert and confident?
2 What is the effect of ethanol on the nervous system that leads to slow reflex action?
3 Continuous consumption of large amounts of alcoholic drinks can cause chronic scarring, hardening and failure of the liver, a condition known as liver .
4 Excessive alcohol consumption causes unclear speech by negatively affecting parts of the in the brain.
