Additional instruments are used to remove stones and or other blockages. Stents may be used to drain an area and open a narrowed area. • Sphincterotomy — abnormalities found during an ERCP study can sometimes be treated at the same time with an endoscopic retrograde sphincterotomy (ERS)‚ a procedure to cut the sphincter muscle between the common bile duct

Neurotransmitters Neurotransmitters are chemicals made by neurons and used by them to transmit signals to the other neurons or non-neuronal cells (e.g.‚ skeletal muscle; myocardium‚ pineal glandular cells) that they innervate. The neurotransmitters produce their effects by being released into synapses when their neuron of origin fires (i.e.‚ becomes depolarized) and then attaching to receptors in the membrane of the post-synaptic cells. This causes changes in the fluxes of particular ions across

hand and raising your arm. It requires communication 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

1. Explain the role of neurotransmitters in formation of drug addiction. As we can see from the video assigned to us this week‚ dopamine is a neurotransmitter that plays a role in the brain’s response to the presence of drug abuse. Dopamine is responsible for movement‚ regulation of heart rate‚ motivation and how a person perceives an experience either being painful or pleasurable. Pain causes for dopamine levels to drop whereas pleasurable responses increase dopamine levels. All drugs that become

Impact of Neurotransmitters on Physical and Mental Behavior Physiological Psychology November 20‚ 2011 Neurotransmitters are powerful chemicals that regulate numerous physical and emotional processes such as mental performance‚ emotional states and pain response. Virtually all functions in life are controlled by neurotransmitters. They are the brain’s chemical messengers. Interactions between neurotransmitters‚ hormones‚ and the brain chemicals have a profound influence on overall health and
