Label the neuron

Cell 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 side

Neurotransmitters

Deals with behavior within groups and the influence of social factors to the individual

describe the structure of a neuron and the process by which an action potential is triggered

Each 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 body

Blood brain barrier

discuss the significance of endorphins, and explain how drugs influence neurotransmitters

Endorphins 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 endorphins

describe how nerve cells communicate, and discuss the importance of neurotransmitters for human behavior

When 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.
