"Neuron" Essays and Research Papers

1 - 10 of 500


Neurons are cells used to perceive the outside environment, the internal environment within themselves, to formulate behavioral response to those signals, and to send that information to other neurons, muscles, or glands. All information comes into a neuron through the dendrite, flows through the neuron and then leaves to go to the next neuron through the axon. Neuron communication does not rely on a single entity but entrusts several different processes that involve the contribution of neuron structure...

Neuron Disorders

While neuron disorders are debilitating diseases, scientists are researching promising new cures. This research ranges from the crosstalk between motor and sensory neurons, to the morphing of skin cells, and the function of the CLP1 gene and its role in certain diseases. A first example of this promising new research is that scientists have discovered that ephrin and Eph prevent spinal cord neurons from regenerating after injuries. This means that if scientists can coax the neurons that are injured...

Physiology: neurons, hormones and obesity.

the connections between neurons in the brain, gain insight into the regulation of appetite and metabolism. The ARC and VMH has long been thought of as satiety centers. Studies that investigate the role of the arcuate nucleus in the hypothalamus, in regulating appetite and metabolism, have targeted two chemically identified neuronal types within the ARC: anorexigenic pro-opiomelanocortin (POMC) neurons and orexigenic neuropeptide Y (NPY)/agouti-related peptide (AgRP) neurons. The melanocortin α-melanocyte...

Neuron and Axon Dendrite Cilia

Exp #2: Organization of Nervous Tissue Exercise 1: Multipolar Neurons Paste an image found on LabPaq site or Google images of a spinal cord smear and label its basic parts using basic labeling boxes provided. Identify the cell body, the nucleus, the large nucleolus, and granular Nissl bodies on the slide. Try to find the axon and differentiate it from the dendrites if possible. Hint: after pasting image, right click on it and select “order”, “send to back”. cell body nucleus large...

Neurons, the Basic Elements of Behavior

Neurons, the Basic Elements of Behavior PSY 101 16 January 2011 One of the most basic yet complex systems in the universe is the biological organism, with even the simplest person being considered the most intricate and advanced biological entity alive. Each person’s actions are controlled by the brain, which when broken down to the simplest explanation is essentially the most advanced computer in the world and just like a standard home computer the brain is made up of several pieces to function...

Neurons: the Basic Elements of Behavior

Neurons: The Basic Elements of Behavior Neurons, or otherwise called nerve cells, are the basic elements of our nervous systems. We have as many as one trillion nerve cells throughout our bodies. These cells are responsible for controlling our behavior. So what is a neuron? “A neuron is a nerve cell that is the basic building block of the nervous system. Neurons are similar to other cells in the human body in a number of ways, but there is one key difference between neurons and other cells...

Neurons: Nervous System and Cell Body

The building blocks of our body ' s neural information system are neurons. Each neuron is composed of dendrites, a cell body, axon with myelin sheath, and vesicles with neurotransmitters. The neuron receives information from sense receptors or from chemical messages from neighboring neurons via its dendrites, which pass the information to the cell body. The cell body fires an impulse, called the action potential, down the axon. The impulse is protected and sped along its way by the myelin sheath...

Signal Travelling in Neurons

Traveling in Neurons Two opposing ideas about the nervous system * Reticular theory ( the nervous system consisted of a large network of fused nerve cells) * Neuron theory ( the nervous system consisted of distinct elements or cells * Discovery of staining led to the acceptance of neuron theory. Staining is a chemical technique that caused nerve cells to become colored so they stood out from surrounding tissue * A way of electricity is transmitted in groups of neurons, such as the...
