CNS/PNS
Smaller, more prevalent cells that serve supportive functions to the neurons
What are Glial/glial cells?
The cranial nerves and the spinal nerves and their branches.
What is the Peripheral Nervous System made up of?
post synaptic neurons
What are the neurons receiving the neurotransmitter after the synapse called?
adenosine
Which neurotransmitter dampens all neuronal activity in the whole brain, it is inhibitory.
The psychoactive drug that passes directly from the stomach and small intestine into the bloodstream, reaches the brain in less than a minute where it diffuses through cell membranes slowing electrical messages. The second most widely used drug.
What is alcohol?
Division of the Autonomic Peripheral Nervous System which controls the rest and digest functions
What is the parasympathetic nervous system?
Division of the autonomic Peripheral Nervous System which controls the fight, flight or freeze reactions
What is the sympathetic nervous system?
Parkinsons
Which disease may be due to a loss of dopamine?
norepinephrine
What is the neurotransmitter that puts you on hyper-alert ?
The psychostimulant drug that binds the adenosine receptor and keeps us from falling asleep. Enhances the release of adrenaline. Most widely used drug.
What is caffeine?
brain and spinal cord
what makes up the Central Nervous System (CNS)?
Division of the Peripheral Nervous System which controls the skeletal muscles (voluntary actions)
What is Somatic Nervous system?
Neurotransmitters contained in membrane-bound vesicles are found
What is an axon bulb?
inhibitory neurotransmitters that are natural painkillers, analgesics that inhibit pain
What are Endorphins, enkephalins, and anandamides?
The psychostimulant drug that mimics acetylcholine (ACh)? Reduces fatigue, enhances memory and learning, and improves motor skills. The third most widely used drug.
What is nicotine?
An insulating coating around the axon helps electrical messages move faster
What is a myelin sheath?
performs higher mental function
what is the cerebrum?
chemical messengers that convey information from other neurons through the synaptic cleft
What are neurotransmitters?
An inhibitory neurotransmitter that regulates mood.
What is serotonin?
A group of drug that crosses the blood-brain barrier and interacts with the brain
What are psychoactive drugs?
Part of the nervous system that conducts information to and from the brain
What is spinal cord?
Monitors and coordinates movement
What is the function of the cerebullum?
Neurons send the neurotransmitters into the synapse
What are pre-synaptic neurons?
A major excitatory neurotransmitter in the brain. It enhances communication between neighboring nerve cells
What is glutamate?
An entirely preventable condition in babies because of exposure to alcohol during weeks 3-8 of gestation is called
What is fetal alcohol syndrome?
