What is an action potential? To put it simply‚ it is a message that is sent down the nervous line. The message is written and is sent from the central nervous system. That message is addressed to muscles or glands. This essay will explain what happens before‚ during‚ and after an interneuron action potential. To accurately define an action potential‚ it is part of the incredible course of events that occur during the firing of a neuron. When a neuron is not firing signals‚ the interior of the

t is important to mention the Neuron as carrier impulses from the CNS to the periphery‚ the peripheral nerves in turn have the funsion to carry messages from one part of the organism to another‚ so we can understand the action of these drugs. They act in the prevention‚ generation and propagation of the nervous impulse. Acting on the blocking of the depolarization initiation‚ allowing Na + to enter the nerve cell from rest to the trigger threshold (- 50a - 60 mV) would consequently impede the initiation

Nerve and neuron sound similar to most people‚ but they are two different components of the body (Martini‚ 375). Nerves are found only in the peripheral nervous system‚ while neurons are found in the brain‚ spinal cord‚ and peripheral nerve (Martini‚ 375). Neurons are nerves cells that are specialized for intercellular communication (Martini‚ 375). A neuron is composed of a cell body‚ dendrites and axon (Marieb‚ 376). A nerve is a bundle of axons or dendrites that is wrapped in connective tissues

The most important event of Mexico’s history The independence war was the most important historical event in all the history of Mexico. This event occurred in the 19th century between 1810 and 1821 and had different stages.

I have two reasons of why is the most important event of the history of Mexico

1. You are looking at a neuron under a microscope. You find many structures coming off the cell body. Some of these are relatively thick and branch many times. One of the structures‚ however‚ is very thin and very long. This latter structure is most likely the neuron’s __________ ‚ which carries the __________. a. dendrite; efferent signal b. dendrite; afferent signal c. axon; action potential d. axon; receptors 2. If the myelin sheathing on neurons is absent or removed in a given individual

Effect of ions on living organisms (24 marks) An ion is a charged atom or molecule. This is because it does not have an equal amount of protons and electrons‚ therefore giving the atom an overall charge. An example of an ion is ‚ this is sodium and the plus sign represents an overall positive charge. Ions are very important to living organisms as they are essential for life‚ they play an important role within the cell allowing mechanisms within the living organisms such as respiration‚ to take
