The mechanism by which neurotransmitters excite and inhibit the postsynaptic neuron. Introduction: Neurotransmitters are small chemical groups that are released from the axon terminals of the neurons. They bind to the specific receptors that are present on the next neuron, called post-synaptic neuron, and initiate a series of reactions that result in the generation of the action potential. The neurotransmitter receptors are present in the form of ligand-gated ion channels, where ligands are the neurotransmitters themselves. They bind to the receptors and initiate the opening of the voltage-gated ion channels. The neurotransmitters might excite the neuron or inhibit it, depending upon the type of voltage-gated ion channels that it has triggered to open.

You have been hired as a public relations specialist to give invertebrates a good name. After all, they are much more than just creepy crawly bugs! Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.
