How is a neuron like atoilet for therhold and all-or none properties Essay

How is a neuron like atoilet for therhold and all-or none properties - Essay Example The neurons are stimulated when they reach a specific level which is known as the threshold. Every neuron has its own threshold on which it can be stimulated. Below the threshold the neuron is not stimulated enough to fire impulses to cause its desired effect. This is known as the all or none property followed by all the neurons of the body. The threshold and the all or none law can be compared to the toilet. When the toilet is in the normal position without any interaction it is known to be in the resting position. This can be compared to the resting membrane potential of the neurons in which the neuron is not firing impulses. Similarly when the toilet has to be flushed the lever is to be pushed hard enough so that the flushing can begin. Same is the case with neurons which have a stimulatory threshold level which can only be achieved if the resting membrane potential has reached the threshold level. As the flush won’t work with the right power the neurons will also not work with the right stimulatory power. When the process of flushing starts it reaches a peak when the water stops being drained after which the water is poured back in the toilet.

An important family story or story some one told you Essay

An important family story or story some one told you - Essay Example He picked on everyone but he wasn’t so tough the woods didn’t scare him, at least a little. The woods were where suburbia and our world as we knew it ended, about two blocks from our street. Sometimes we would venture to the edge peering into the thick brush wondering how far it went, maybe to the ocean about 1000 miles away, we didn’t know. The few times we got close were when the trees were bare in the cold months. When the trees and brush was full with leaves you couldn’t see more than a few yards. The woods were that thick and that scary. When I asked my parents about the woods they answered with whatever they thought would satisfy my curiosity, in other words shut me up, but didn’t seem to know anything about what was in or beyond the thick treed darkness. It was dark, even in broad daylight. The woods were the perfect setting for nightmares and most kids must have had the same dreams because nobody would dare walk into the darkness. It was rumored that an old abandoned house was somewhere in the woods. This story was told by the much older kids who said they had been in it but nobody believed them. It wasn’t possible because nobody went into the woods, absolutely nobody. The house became an obsession with me and my friends, where was it, who lived there and what secrets was it hiding? We thought a murder likely happened there or at least somebody died in that house. Maybe there body is still there. Maybe the murderer still lives there, safe because nobody, not even the police would dare go. Yes, it was that frightening to a group of young kids whose imagination was fully engaged. Imagination was a large part of our lives at the time. We imagined being soldiers, sports stars, pop stars, or whatever. Imagining horrible secrets lurked in the house in the woods came easy for us. We became almost certain the house was haunted. It had to be because the woods certainly were haunted. One summer two
