FCA1: Student answer reflects accurate knowledge of the sequence of events that construct a nerve signal (message sent from where and going where?). FCA 2: Student answer contains proper descriptions for each of the following terms: axons, dendrites, neurons, terminal buttons, soma, synapse, receptor sites, neurotransmitter FCA 3: Student's answers to neurotransmitter scenario questions display evidence of an understanding of the effects of various neurotransmitters by providing a logical choice(s) and appropriate evidence to support that choice.

Question: Explain the process of information exchange that occurs in the brain. Be sure to include information on axons, dendrites, neurons, terminal buttons, soma, synapse, receptor sites, neurotransmitter.

Neurotransmitters carry messages from neuron to neuron using dendrites, which is a short branched extension of a nerve cell. 'Neuro' means brain and 'transmitter' means message carrier. Dendrites pass messages containing neurotransmitters through synapses, a junction between nerve cells. The soma is the main part of the neuron, and it maintains the life sustaining functions of the neuron. The soma processes the messages, and then sends them along a long threadlike part of a nerve cell, called an axon, until they reach the end, where there are little bulbs called terminal buttons. The terminal buttons pass messages on to glands, muscles, or other neurons. They then pass through the synapse, where are caught by the dendrite of the next neuron by receptor sites, groups of nerve endings.

A woman training for a marathon just completed running 5 miles out of the 10 miles she will run for her training sessions today, some neurotransmitters that might be involved in this act would be epinephrine, dopamine, and endorphins. Epinephrine it deals with energy, and dopamine because it plays a key role in regulating pain & pleasure, which exercising is a mixture of both. Lastly, endorphins because when you...
