2932876578explain why psychologists are concerned with human biologybiological processes underlie every aspect of our behavior and mental processes. By studying the links between biology and psychology, biological psychologists achieve greater understanding of such behaviors like sleep, hunger, sex, stress, disease, depression and other human conditions0
2932888964In the most basic sense, every idea, mood, memory, and behavior than an individual has every experienced is a ________________ phenomenonbiological1
2932890731the theory that linked our mental abilities to the bumps on our skull was _______phrenology2
2932893875researchers who study the kinks between biology and behavior are called ___________________________biological psychologists3
2932898212explain why, at every level, our existence is both part of a larger system and a combination of smaller systemsBody organs such as the stomach, heart, and brain, which are composed of smaller systems (cells), form larger systems for digestion, circulation, and information processing, which are part of an even larger system- The individual as a person, who intern forms a part of the family, community, and a culture. we are bio-psycho-social systems4
2932899054describe the structure of a neuron and the process by which an action potential is triggeredEach neuron consist of a cell body, branching fibers call dendrites that receive information from other neurons, and then extension fiber called an axon through which the neuron passes information to other neurons or two muscles or glands. Some axons are insulated with a myelin sheath, which helps speed neural impulses. And there'll impulse, or action potential, occurs if the excitatory signals minus the inhibitory signals received by the neuron on its dendrite or cell body exceeds the neurons threshold. Then, the gates of the axon open, allowing positively charged atoms to rush inside. This depolarizes that part of the axon, which causes the axons next chance open and leads to the electrical chain reaction by which electrically charged Adams ions travel down the axon into junctions with other neurons and with the muscles and glands of the body5
2932904925describe how nerve cells communicate, and discuss the importance of neurotransmitters for human behaviorWhen action potential reaches the end of the axon, chemical messengers called neurotransmitters are released into the synaptic gap between the sending and receiving neuron. This junction is called a synapse. Neurotransmitter molecules bind to receptors sites on the receiving neuron and have either an excitatory or inhibitory influence on that neurons tendency to generate its own action potential. If the receiving neuron receives more excitatory then inhibitory inputs, more neural impulses are generated. A particular neural pathway may use only one or two neurotransmitters, each of which may have a specific effect on behavior.6
2932907048discuss the significance of endorphins, and explain how drugs influence neurotransmittersEndorphins are morphinelike neurotransmitters found in the brain that are released in response to pain and vigorous exercise. The existence of endorphins may help explain good feelings such as the "runners high", the painkilling effective of acupuncture, and the indifference to pain in some injured people Drugs have a number of different effects on neurotransmitters. Some, agonists, mimic a particular neurotransmitter; other, antagonists, block a particular neurotransmitter. Still others interfere with the breakdown or reabsorption of a neurotransmitter. Opiate drugs, for example, may cause the brain to stop producing endorphins7
2937813243NeuronsA nerve cell; the basic building block of the nervous system8
2937815855DendriteThe bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body9
2937822042AxonsThe extension of a neuron, extended and branching terminal fibers, through which messages are sent to other neurons or to muscles or glands10
2937826005Myelin sheathA layer of fatty tissue segmentally encasing the fibers of many neurons; enables vastly greater transmission speed of neural impulses as the impulse hops from one node to the next11
2937840071Action potentiala brief electrical charge that travels down an axon. The action potential is generated by the movement of positively charged atoms in and out of channels in the axon's membrane12
2937847963Label the neuronCell body: The area around the green dot Dendrites: the spidery branches on the left side Axon: the yellow pieces in the middle Myelin sheath: The casing around the yellow Neural impulse: the impulse that travels from the left side to the right side Terminal branches of axon: the spidery branches on the right side13
2938136934Resting potentialThe positive outside, negative inside polarization that occurs because an unmyelinated axon's membrane is selectively permeable14
2938163865ThresholdThe level of stimulation required to trigger a neural impulse15
2938173572SynapseThe junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron. The tiny gap at this junction is called the synaptic gap or cleft16
2938177954NeurotransmittersChemical messengers that traverse the synaptic gaps between neurons. When released by the sending neuron, neurotransmitters travel across the synapse and bind to receptors sites on the receiving neuron, thereby influencing whether it will generate a neural impulse17
2938187877ReuptakeThe process by which excess neurotransmitters are reabsorbed by the sending neuron18
2938211558DopamineInfluences movement, learning, attention, and emotion Excess activity at dopamine receptors has been linked with schizophrenia If the brain is starved of dopamine, the brain produces the tremors and decreased mobility of Parkinson's disease19
2938218752SerotoninAffects mood, hunger, sleep, and arousal. Undersupply linked to Depression Prozac and similar antidepressant drugs raise serotonin levels20
2938233875Gamma-aminobutyric acid (GABA)Serves inhibitory functions and is sometimes implicated in eating and sleep disorders, undersupply linked to seizures, tremors and insomnia21

2938223543NorepinephrineHelps control alertness and arousal, undersupply can depress mood24
2938248516AChIs one of the best understood neurotransmitters. In addition to its vital role in learning and memory, ACH is the messenger every junction between a motor neuron and a skeletal muscle25
2938257963Endorphins"Morphine within" - natural, opiate like neurotransmitters linked to pain control and a pleasure26
2938278067AgonistsExcite by mimicking a particular neurotransmitter or blocking it's reuptake. An agonist can be a drug molecule that is similar enough to the neurotransmitter to mimic its effect. Some opiate drugs, for example, produce a temporary high that ampliiesy normal sensations of arousal or pleasure27
2938287040AntagonistsInhibit by blocking neurotransmitters or by diminishing their release. An antagonist can be a drug molecule that is enough like the natural neurotransmitter to occupy its receptor site and block it's effect but not similar enough to stimulate the receptor, rather like foreign coins that fit into, but won't operate, a soda or candy machine28
2938302642Agonists and antagonists29
2938311706Blood brain barrierEnables the brain to fence out unwanted chemical circulating in the blood, and some chemicals don't have the right shape to slither through this barrier30
2938330315PhrenologyThe theory about the bumps and groves on the brain31
2938359246Franz GallSuggested that bumps on the skull represented mental abilities, his theory, though incorrect, never the less proposed that different mental abilities were modular32
