Cocaine blocks the reuptake of what?
catecholamines which causes: Increased BP- can lead to stroke Cardiac Acceleration- leads to dysrhythmias (impaired electrical activity) Vasoconstriction- leads to Stroke or MI CNS stimulation- leads to seizures Anticholinergics- leads to gastric ulcers
Prozac functions as an antidepressant because it?
blocks the reuptake of serotonin.
A drug that mimics the effects of a particular neurotransmitter or blocks its reuptake is called?
an antagonist
What are sertraline capsules for?
Sertriline (Zoloft) Selectively blocks reuptake of serotonin, enhancing serotonergic function. It is an antidepressant.
Does cocaine effects the nervous system?
It is a norepinephrine reuptake inhibitor. Norepineprhine is a stimulating neurotransmitter. It makes you feel up, energetic, and hyperactive. It also increases your heart rate and blood pressure. When norepinephrine is released from nerve cells in the synapse to send a signal on to the next nerve cell, there is a reuptake pump that removes the norepinephrine to cut the signal off. This keeps the pathway from firing to much or too long and preserves the norepinephrine for future use. Cocaine blocks the reuptake system and makes the stimulating stronger and last longer. However it that means that you also deplete your supply of norepinephrine and "crash". This makes you feel tired. So you keep wanting more cocaine to get back to that good (high) feeling, but because you have used up the norepinephrine you never quite reach it. That makes cocaine very addictive.
What neurotransmitter does methamphetamine cause the brain to release?
Cocaine and crack cocaine are psychostimulants that affect neurons containing dopamine in the areas of the brain known as the limbic and frontal cortex. When cocaine is used, it generates a feeling of confidence and power. However, when large amounts are taken, people "crash" and suffer from physical and emotional exhaustion as well as depression.
Cocaine produces intense feelings of well-being because it?
blocks the reabsorption of dopamine
How cocaine effects your brain?
The neurotransmitter dopamine transmits brain signals by flowing from one neuron into the spaces between neurons and attaching to a receptor on another neuron. Normally, dopamine then is recycled back into the transmitting neuron by a transporter molecule on the surface of the neuron. But if cocaine is present, the drug attaches to the transporter and blocks the normal recycling of dopamine, causing an increase of dopamine levels in the spaces between neurons that leads to euphoria. Cocaine, however, attaches to the same transporter binding sites as dopamine. This means that, when cocaine is introduced, dopamine cannot bind to the dopamine transporter and is stranded in the synapses. Thus, cocaine's blocking action leads to an increase of dopamine levels in the synapses that, scientists believe, normally produce feelings of pleasure. Cocaine's action intensifies these feelings into euphoria, studies show. it makes you trip out you start seeing things it makes you loose weight according how does your body take it sometimes it just makes you get inflated (fat) it dialetes your eyes and on the come down you probly make all your body hurt your muscles
How do cocaine and alcohol affect the brain?
Cocaine blocks the reuptake of dopamine and, to a lesser extent, norepinephrine and serotonin in the brain. This causes the accumulation of dopamine, leading to euphoria and excitation. The increased stimulation of dopaminergic neurons in the mesolimbic (reward) circuit leads to addiction. Alcohol binds with GABA receptors producing inhibitory effects on neural activity. This produces cognitive impairment and reduced anxiety (disinhibition). Activation of GABA receptors also produces postsynaptic dopamine release, which stimulates the mesolimbic circuit in the brain, producing euphoria and addiction.
What form does cocaine come in?
it comes in blocks,liquid,sand,powder hello my name is john arron whats your name
Nutrients considered to be building blocks for body development are?
Proteins.
