Question: Explain the process of information exchange that occurs in the brain. Be sure to include information on axons‚ dendrites‚ neurons‚ terminal buttons‚ soma‚ synapse‚ receptor sites‚ neurotransmitter. Neurotransmitters carry

These chemical messengers‚ called neurotransmitters‚ are released and received by the brain’s many nerve cells‚ which are also called neurons. Neurons are constantly communicating with each other by way of exchanging neurotransmitters. This communication system is essential to all of the brain’s functions. A tiny space called a synapse connects neurons to one another. Depression has been linked to problems or imbalances in the brain with regard to the neurotransmitters serotonin‚ norepinephrine‚ and

terminal neurotransmitters are stored ready to be released‚ across the synaptic gap‚ when the action potential arrives. The receptors on the post-synaptic neurone become occupied with the neurotransmitters resulting in a change in electrical charge. The neurotransmitters can either cause inhibition of the post-synaptic neurone‚ by suppressing the activity of the neurone and returning to the resting potential or excitation where by the activity of the neurone is increased. Each neurotransmitter resembles

Drugs and the nervous system Neurotransmitters within the body include excitatory and inhibitory‚ noradrenalin‚ dopamine‚ serotonin; acetylcholine and glutamate are examples of excitatory neurotransmitters. GABA and glycine are examples of inhibitory neurotransmitters. General anaesthetics General anaesthetics act mainly on the central nervous system to stop information processing; these may be given by inhalation or intravenously. Nitrous oxide or laughing gas is used in maintain anaesthesia

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

When substances like acetylcholine and norepinephrine are released in the body‚ they tend to bind to receptors‚ tissues and neurons. These neurotransmitters transfer signals throughout the nervous system and stimulates action potentials in the postganglionic neurons. Receptors found on the ANS and PNS includes the cholinergic receptors‚ which consists of all sympathetic and parasympathetic preganglionic‚ sympathetic postganglionic and all parasympathetic postganglionic neurons. The cholinergic receptors

An electoral signal‚ called an action potential travels down the axon and to the axon terminal. At the end of the motor neuron are structures called synaptic vesicles and they contain different neurotransmitters. In the case of a motor neuron that stimulates a skeletal muscle fiber‚ that neurotransmitter is called acetylcholine. When the action potential gets down to the end it will cause the synaptic vesicles to release acetylcholine. The ACH crosses the synapse‚ which is a physical gap between
