chemical substances to synapses (messages to the other cells). (Pinel, Jonh, 2003.) The messages that travel through the neuron are exclusively of an electrical nature. They follow a route that begins in the dendrites, continues towards the body of the cell and arrives, finally, towards the extension in the form of a tube. In order to prevent messages from making short circuit, it is necessary that the axon has some type of insulator (similar to the way the electrical cables are isolated). In this way, most axons are protected by a coating known as myelin sheath, composed of a series of specialized cells that contain fats and proteins that surround the axon. Synapsis is a union (functional) (Bear...
chemical, physical or biological agents in the environment, which have harmful effects on the health of living beings. Examples of these agents include gases emitted in industrial processes, toxic spills and non -biodegradable waste generated in the production of goods and services. One of the main consequences of pollution is global warming, whereby the atmospheric temperature, as well as that of the oceans, is increasing progressively. This climate change is causing natural disasters such as droughts and hurricanes, and could result in the disappearance of animal and plant species, not only devastating the natural balance of the planet, but also causing hunger and destruction.
