Nerves-n-Thangs
This subdivision of the nervous system consists of the brain and spinal cord.
the central nervous system (CNS)
These are specialized cells that transmit electrical signals
Neurons
The belief that we are heavily influenced by everything from our family and friends to our culture and experiences.
Nurture/Environment
alcohol can be classified as
A depressant
This is known in the body as the need to take more of a drug to achieve the same effect.
Tolerance
This subdivision relays messages between the central nervous system and the rest of the body
peripheral nervous system (PNS)
These cells function to protect, nourish, and clean up after neurons
Glial Cells
The idea that behaviors have evolved because they helped our ancestors survive and reproduce. Traits that enhance survival, get passed on
Natural Selection
Substances that affect brain activity and lead to changes in perception, mood, or consciousness.
Psychoactive drugs
This is known as an automatic, rapid response to a stimulus. This bypasses the brain for a quicker reaction.
This subsystem of the peripheral nervous system controls voluntary actions
somatic nervous system
This is the neuron’s control center. It houses the nucleus and produces energy for the cell.
Soma
These individuals share about 50% of their genes, just like other siblings
Fraternal Twins (Dizygotic)
Drugs that block neurotransmitter activity.
Antagonist
High levels of this neurotransmitter are associated with chronic pain conditions, such as arthritis and fibromyalgia.
Substance P
This subdivision is responsible for "rest and Digest)
Parasympathetic
This is known as the "talker" of the neuron
Axon
How our environment can influence gene expression without changing the DNA itself (e.g., stress might turn certain genes on or off).
Epigenetics
The drugs that block the reabsorption of neurotransmitters in the synapse during neural transmission are...
Reuptake Inhibitors
This disorder happens when the myelin sheath is damaged, slowing down or blocking signals.
MS- Multiple Sclerosis
This system processes information and makes decisions______while the ________carries out the instructions.
CNS & PNS
These are known as the "listeners" of the neuron. Receive incoming signals from other neurons.
Dendrites
This is known as the controversial idea of improving human populations by selective breeding and controlling reproduction.
Eugenics
This category of drug stimulates the central nervous system by increasing the release of the neurotransmitters dopamine, norepinephrine, and serotonin throughout the brain
Amphetamines
This hormone stimulates Hunger....
Ghrelin
