Understanding Neurons Essay

626 words - 3 pages

Neurons are the messengers' of our body, by using electrical and chemical messages to move information throughout our entire system (National, 2005). Neurons are so important, everything that we think, feel and do would be impossible without the work of a neuron.Within the Neuron there are several parts; the axon and the dendrite. The axon transmits messages from the cell, and resembles a long tail. Dendrites receive the messages for the cell; they resemble the branches from a tree. There is a nucleus within the body which controls the cells activities and contains the cells genetic material (National, 2005). The neuron to me sounds like a large computer system that takes the information in through the dendrites, processes it and then releases it through the axon to were the information needs to go.There are several types of neurons: The neuron that carries information to the eyes, ears, brain and other sense organs are the sensory neurons. The neuron that carries information from the central nervous system to the muscles and glands are the motor neurons, these have long axons in order to communicate these long distances. The interneuron communicates between the sensory and motor neurons, they have short axons in order to do this (Feldman, 2008). Our sensory neurons pick up stimulation from our eye's, nose, mouth, and skin, these cells help with our sight, hearing, touching, smell and taste as well as feeling our muscles and joints, along with keeping our balance. Within the neuron, Pain receptors will respond to the chemical that is produced when you damage your skin, there are receptors that respond to all situations within our body and stimulation from outside sources (Boeree, 2006). Neurons also relate to psychology and our behaviors, Neurons effect how we behave, learn and how we feel and sleep. Neurons also affect mental illness (Heffner, 2003). Research has identified over 50 neurotransmitters in the brain alone....

Artificial Neural Networks Essay

1124 words - 4 pages artificial neural networks. Before understanding the complex structure of an artificial neural network, a rudimentary knowledge of an organic neural network is essential. The human brain consists of over billions of neurons interconnected by trillions of synapses. Neurons exchange electrical impulses through the synapses attained from other neurons or from the senses. When something novel is experienced, these neurons create new connections

Astrocyte-Neuron Lactate Shuttle and Hemodynamic Brain Scans

1697 words - 7 pages Astrocyte-Neuron Lactate Shuttle and Hemodynamic Brain Scans Hemodynamic brain scans such as Positron Emission Tomography (PET) and functional Magnetic Resonance Imaging (fMRI) have been of immense utility in the neuroscience fields in illuminating the components and modulation of brain function. However, these hemodynamic brain scans have afforded utility without brain scientists truly understanding the mechanism by which they produce signals


1612 words - 6 pages Neurotransmitters Neurotransmitters are chemicals made by neurons and used by them to transmit signals to the other neurons or non-neuronal cells (e.g., skeletal muscle; myocardium, pineal glandular cells) that they innervate. The neurotransmitters produce their effects by being released into synapses when their neuron of origin fires (i.e., becomes depolarized) and then attaching to receptors in the membrane of the post-synaptic cells. This

Relating Autism and Mirror Neurons

1733 words - 7 pages deficit and struggle with social interaction in children with autism to the mirror-neuron system not functioning properly. Researchers found that mirror neurons preform the same functions that are disrupted in Autism. Therefore, it can be hypothesized that one cause of Autism is a dysfunctional mirror-neuron system, given that the presumed functions of these class of neurons – such as empathy, intention-reading, mimicry, pretend play, and

Amyotrophic Lateral Sclerosis

1278 words - 5 pages excessive exposure to glutamate may be the reason that motor neurons die (Jones, 2013). If they could prevent the rise in glutamate levels that could be the key to protecting the motor neurons and slowing, or even stopping the progress of ALS. Researches understanding more about the mechanisms that increase levels of EAAT2, this component is supposed to remove excess glutamate before it can build up and damage motor neurons (Jones, 2013). Once they

Understanding Brain Chemistry

Is it that we analyze our own mental processes, as well as the processes of others? What exactly is a mental state, and what creates it? Is it a level of attentiveness, an impulse, or an emotional state? What is it that allows us to experience these things? The answers

The nervous system and its bodily functions.

Neurons The neuron has two important structures called the dendrite and axon, also called nerve fibers. The dendrites are like tentacles that sprout from the cell and the axon is one long extension of the cell. The dendrites receive signals from other neurons, while the axon sends impulses to other neurons. Axons can

The synapse is the location at which the electric signals of one neuron

Nitric Oxide (NO) and the Nervous System

Relaxation of the cerebral arteries can be blocked by a synthetic arginine derivative N-nitroarginine (Snyder 1992). In these systems, NO satisfies several common criteria for a neurotransmitter: NOS

A seizure can occur due to any number of reasons, for example, a head injury, low blood sugar, a fever, or even imbalanced electrolytes. A seizure can be defined as a short-termed change of behavior due to the excessive and synchronous firing of central nervous system(CNS) neurons.1 There are many different physiological causes that can result in the occurrence of a seizure

Phantom Limbs: A Neurobiological Explanation Essay

988 words - 4 pages understanding and trying to treat the phenomenon. Since the senses are prompted by sensory neurons, phantom pains must also be the result of action in sensory neurons. However, if the leg is no longer attached to the body, then how can the neurons in the leg transport signals to the nervous system in order for the body to feel sensations? One possible explanation is the existence of neurons from the phantom limb even after amputation. Even though the
