unison in order for the body to perform the tasks it is told to perform. The brain is responsible for controlling both voluntary and involuntary actions and coordinates and controls other organs in the body. The brain can do this by the use of postsynaptic potentials‚ synaptic transmission‚ and receptors that are responsible for producing and regulating specific behaviors. There are also six primary neurotransmitters that play a large role in how an individual behaves and how their brain functions. The

Discover Your Products’ Hidden Potential by Ian C. MacMillan and Rita Gunther McGrath A simple matrix helps you identify the attributes that will make your goods and services most competitive. Why did a minor math error that would occur only once every 27‚000 years so enrage customers that it briefly threatened to derail Intel’s Pentium chip? And how could a feature as trivial as an inexpensive cup holder swing millions of customers to purchase a $17‚000 automobile—particularly when only

Introduction Munchy’s company is one of food company type which in variety of biscuits‚ wafers‚ cracers and cookies type. In Malaysia‚ the headquarters succesfully established at Johor‚ around 1991. The Munchy’s term was derived from the Mandarin term “Mai Oi”.”Mai” which means flour or wheat and “Oi” that refers to the magical quality found in it’s delicious wafer.Nowadays‚ the brands distributed all over country including Asia Pacific‚ Europe‚ Middle East‚ Africa‚ North America and Latin America

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 vast majority are chemical. Electrical synapses are located in the retina and in some
