OBJECTIVES 1. Explain why psychologists are concerned with human biology. 2. Describe the structure of a neuron‚ and explain how neural impulses are generated. 3. Describe how nerve cells communicate‚ and discuss the impact of neurotransmitters and drugs on human behavior. 4. Identify the major divisions of the nervous system and describe their functions‚ noting the three types of neurons that transmit information through the system. 5. Contrast the simplicity of the neural

Get valium prescribed to tamp down depression Depression is a mood disorder whereby an individual feels continuous sadness‚ hopelessness as well as being unimportant and most of the time he or she is unable to live a normal life. This condition is common in the society. That is why there are various medications for instance Valium‚ which is used to curb depression. Downheartedness just like any other disorder can be managed by use of prescription. Valium is one of the many drugsused for depression

Describe the life cycle of a typical neurotransmitter. A cell membrane with the uptake of a particular precursor absorbs amino acids to create a neurotransmitter. The amino acids undergo synthesis with a reaction with enzymes to become a neurotransmitter. Once created‚ the neurotransmitters are stored in vesicles until they are released into the synapse. Once released‚ the neurotransmitters will attempt to attach to the membrane of neurons. If the neurotransmitter does not make it to the neuron‚ then

For the purpose of this assignment I will be looking at this question in two parts. Firstly I will explain how neurons transmit information in the human body and secondly I will discuss how knowing how neurons function within our bodies helps us understand different aspects of human behaviour. I will be using information gathered from Book 1 (Mapping Psychology). External and internal factors and conditions are detected by the body’s nervous system. These changes are detected‚ interpreted and

sheath…we’ll talk later about demyelinating diseases such as MS and Guillian Barre. Neurotransmitters – neurons generate and conduct electrical and chemical impulses by selectively changing the electrical portion of their plasma membranes and influencing other neurons by the release of neurotransmitters. Many neurological disorders are due in part to an imbalance in neurotransmitters. Acetylcholine (major neurotransmitter of the ParaSNS ) Serotonin‚ Dopamine‚ Norepinephrine (SNS)

is a tiny gap between two neurons known as the synapse. Neurotransmitters cross the synapse from one neuron to another and attach onto the receptors of the receiving neuron. Neurotransmitters and receptors have a lock and key relationship; therefore‚ only specific neurotransmitters will fit into a certain receptor. It is suggested that depression can be caused by a chemical imbalance in the brain such as an imbalance of the neurotransmitters serotonin and dopamine. They have been identified as playing

the form of an electrical signal known as an action potential. Neurotransmitters are needed to send the information from one neuron to the next. Neurotransmitters are chemical messengers that are released from the axon terminals to cross the synaptic gap and reach the receptor sites of other neurons. 3.) Telondendria are the terminals or branches of an axon that terminates or where the axons split off and releases neurotransmitters 4.) The nissl body is a large granule body found in neurons

focusing on the material below. Enjoy! Why is drug withdrawal a painful experience for addicts? Using drugs puts an excess amount of neurotransmitters in the body. When there is an overflow the brain stops making it naturally and when the drug wears off it takes time for the brain to star making the chemical once again on its own system. Some neurotransmitters are dopamine‚ serotonin‚ Acetylcholine‚ Norepinephrine‚ Gamm-amniobutyric acid‚ Endorphins. Endorphins are natural opiates. Broca’s area
