gets too close to a candle. Their nervous system sends the stimulus to the brain‚ which tells the finger to back away from the flame. However‚ the synapses wouldn’t happen without neurotransmitters. These are chemicals that flow through neurons‚ which indicate what should be done next. There are two types of neurotransmitters: excitatory and inhibitory. The excitatory ones commands the neurons to work quickly; the

Site Plan | I. Neurons/nerve cells A neuron is a cell specialized to conduct electrochemical impulses called nerve impulses or action potentials. Neuron is the main cellular component of the nervous system‚ a specialized type of cell that integrates electrochemical activity of the other neurons that are connected to it and that propagates that integrated activity to other neurons. They are the basic information processing structures in the CNS.

Dopamine is Another relative of norepinephrine and epinephrine it is found to be a neurotransmitter in the 1950s by another Swede‚ Arvid Carlsson. It is an inhibitory neurotransmitter‚ implying that when it discovers its way to its receptor locales‚ it obstructs the inclination of that neuron to flame. Dopamine is emphatically connected with reward systems in the mind. Drugs like cocaine‚ opium‚ heroin‚ and liquor increment the levels of dopamine‚ as does nicotine. In the event that it can rest easy

List some common neurotransmitters and describe their effect on behavior. There are 2 neurons afferent neurons these carry messages to the central nervous system. Efferent neurons carry messages from the central nervous system. Neurons communicate through voltage changes. This can sometimes lead to quick action reaction

between your brain‚ muscles and organs. This starts with the neurons. Our organs sense things the brain needs to know. Signals are sent to the brain‚ it is decoded and then tells your brain what muscles to use and how. The signal is sent‚ a neurotransmitter. This is stored in the axon. An electrical impulse starts in the neuron. The charge is sent down the axon and this is how it starts. A neuron has three basic parts: the body or soma‚ the axon and the dendrites. The Cell body is the center
