1. The drug that Harry abuses is a hallucinogens. Hallucinogens are drugs that alter the person's consciousness and arouse the senses in different ways. They can create hallucinations and make the person taking the drug very hungry. One effect of a hallucinogen is that it can increase the way the person perceive sounds, making music sound better than how it did before the “high”. Harry is not abusing a depressant because a depressant reduces neural activity which is not what is happening with him. It’s also not a stimulant because a stimulant increases both neural activity and body functions. Harry’s heart rate and blood pressure did not increase as a result of the drug. Thus, the drug Harry abuses is Marijuana. 2. The drug that Draco abuses is a depressant. Depressants are drugs that reduce neural activity and causes bodily functions(i.e. heart rate) to slow down. This type of drug decreases activity throughout the whole body, especially in the nervous system. It activates the parasympathetic nervous system and causes the body to relax. Draco isn’t abusing a stimulant because a stimulant increases neural activity, which is the opposite of is happening to Draco. He isn’t abusing a hallucinogen because his senses have not been altered nor having hallucinations. It might be an opiate, specifically heroin. 3. …show more content…
The drug that Jo began using is a stimulant. Stimulants increase neural activity and causes bodily functions to speed up. This drug increases activity in the nervous system by activating specifically the sympathetic nervous system, which arouses the body, also known as the fight-or-flight response. The drug that Jo began using is not a depressant since a depressant activates the parasympathetic nervous system. It also is not a hallucinogen because they create hallucinations and in some cases causes the person taking the drug to become hungry. The drug that Jo began using might be Methamphetamine (Crystal Meth).
4a. Neurons communicate using neurotransmitters. First, a neuron has to receive the message through the dendrites, which receive messages. Then, the message passes through the cell body, which is the life support of the cell. Next, the axon receives the message and the neural impulse travels down the axons. The axons are covered by the myelin sheath, which help speed up the neural impulse. Finally, they reach the axon terminal.
4b. Neurotransmitters are the chemical messengers that sends information to a receiving neuron. It is not a hormone because hormones travel through the bloodstream while neurotransmitters travel through the synapse. Also, hormones are messages for organs while neurotransmitters are messages for the neurons. 4c. Serotonin is a neurotransmitter that affects mood (i.e. make someone happy). An agonist is a chemical that mimics a neurotransmitter on a receptor.. The agonist mimics the serotonin neurotransmitter and, hence, causes the person to feel happy. 4d. Serotonin is a neurotransmitter that affects hunger (i.e. make someone feel hungry). An antagonist is a chemical that can bind to a receptor but block its effects. The antagonist that blocks serotonin might make the person not feel hungry. 5. The two subsystems in the peripheral nervous system are the autonomic nervous system and the somatic nervous system. The autonomic nervous system controls the automatic actions of internal organs. The somatic nervous system controls
