transmission process. So in other words the synapse consist of two neurons‚ one of which is sending information to the other. They allow the nervous system to connect to and control other systems of the body. At a chemical synapse‚ one neuron releases a neurotransmitter into a small space (the synapse) that is adjacent to another neuron.

made up of smooth muscle. Smooth muscle is very distinctive from the other types of muscle in the body due to the fact that it is not controlled consciously‚ but unconsciously regulated by the autonomic nervous system through the release of neurotransmitters or hormones (McCance‚ 2014).

not. This anatomical discovery suggests that there is a lack of connectivity between key portions of the brain which control attention‚ stimulus processing and impulsivity. Along with this the neurotransmitters dopamine and norepinephrine are shown to have a part in pathophysiology of ADHD. The neurotransmitter

Biological Psychology Worksheet Answer the following questions in short-essay format. Be prepared to discuss your answers. 1. What is biological psychology? Biological psychology is the study of the effects of brain function-neurotransmitters‚ etc.-on cognitive processes and behavior. If there are abnormalities in the brain‚ thoughts‚ behavior‚ learning‚ memory‚ and other mental and emotional functions are effected. A small chemical imbalance in the brain can be responsible for any

1.) Explain how the use of substances alters a person’s state of consciousness‚ including depressants‚ stimulants‚ and hallucinogens. Include in this explanation what happens to the neurotransmitters and body chemicals as well as how you might recognize if a person at work or in your family is in an altered state of consciousness due to the influence of drugs. The use of substances can alter the person’s state of consciousness in many ways. The depressants‚ stimulants‚ and hallucinogens affect

main types of therapy used is drug therapy. Drug therapy involves issuing a patient psychotherapeutic drug(s) which are used to alter the chemical functioning of the brain by affecting the action of neurotransmitters. Neurotransmitters transmit signals between nerve cells called synapses. Neurotransmitters lead to changes in moods‚ feelings‚ perception and behaviour. The main category of drugs used for treating Schizophrenia is anti-psychotic drugs or neuroleptics. These lessen psychotic symptoms such

Introduction Although stress is an everyday occurrence in life‚ most people take for granted and underestimate the degree to which we are able to influence the level of stress we experience. When we think of the word "stress‚" we usually associate it with something external that causes us to feel stressed. In various research sources‚ adults reveal work as a leading cause of stress (Peterson & Wilson‚ 2004)‚ whereas teenagers revealed that school as one of their biggest sources of stress (Wilburn

behavior of drugs‚ they still take drugs. And as a result‚ many people’s lives were damaged. Drugs often target and alter neurotransmitters‚ the chemical messengers that allow nerves to communicate at their junctions. Repeatedly taking them could interfere the neurotransmitters in the brain‚ leading to addiction. For example‚ drugs like marijuana and heroin mimic natural neurotransmitters. This fools receptors and allows the drug to

subsystems: the parasympathetic nervous system (PSNS) and sympathetic nervous system (SNS).Relatively recently‚ a third subsystem of neurons that have been named ’non-adrenergic and non-cholinergic’ neurons (because they use nitric oxide as a neurotransmitter) have been described and found to be integral in autonomic function‚ particularly in the gut and the lungs. With regard to function‚ the ANS is usually divided into sensory (afferent) and motor (efferent) subsystems. Within these systems‚ however

Final concentration of the holding water was calculated of the neurotransmitter. The animal was allowed to sit with the foil cover on for 5 minutes so that the neurotransmitter can equilibrate between the holding water and the animal’s hemolymph. The trace was started
