Chronic Consumption of Ethanol Alcohol and Neurological Dysfunction Ethanol Alcohol‚ commonly known as Alcohol is the primary mood altering drug used in the United States of America. When alcohol is consumed it is absorbed unaltered by the stomach and the small intestines. Then the ethanol molecules are distributed evenly to all of the tissues and fluids of the body. The alcohol present in the bloodstream is metabolized by the liver through three pathways. The major pathway involves an enzyme

As all behaviour is associated with changes in brain function‚ psychopathology will be caused by changes in either the structure or function of the brain. This might involve changes in the size of brain structures‚ or in the activity of brain neurotransmitters and hormones. For example‚ biological

Neurotransmitters A neurotransmitter is a chemical substance through which one neuron sends a message to another. Neurotransmitters are transmitters that give off chemical reactions to neurons. There are several types of neurotransmitters and each type controls different functions like muscle control and triggers. Axon An Axon is a long‚ arm like structure that transmits

The habeas corpus concept was first expressed in the Magna Charta‚ a constitutional document forced on King John by English landowners at Runnymede on June 15‚ 1215. Among the liberties declared in the Magna Charta was that "No free man shall be seized‚ or imprisoned‚ or disseized‚ or outlawed‚ or exiled‚ or injured in any way‚ nor will we enter on him or send against him except by the lawful judgment of his peers‚ or by the law of the land" (Magna Carta‚ 1215).

Figure 1 shows a neuron‚ as indicated on the diagram; the dendrites are the receivers of information for that cell. The dendrites receive neurotransmitters from the synapses that connect to it and if enough are present‚ an action potential is caused which then travels down the axon to the terminal buttons also known as synapses. There are electrical and chemical synapses in the body although the

passes to the other cell by receptor proteins that work as guards that let or not the information (substance) get through the cell membrane of the receiver cell. In the other hand Synaptic signaling functions through electric signals released by neurotransmitters which also pass through the protein receptors guards located in the cell membrane stimulating the receiver cell. The signals mention before are the two main ways of communication of neurons in your nervous system. Also ionic channels are seen
