This essay will describe the electrochemical processes that allow an Action potential to occur in a neuron. This will be achieved by firstly‚ defining the purpose of neurons in the body along with a description of the components within a neuron and how they enable information to be passed through the cell membrane and on to other neurons. Secondly‚ the resting potential of a neuron will be explored with relation to the concept of selective permeability and the purpose of the Sodium - Potassium

RUNNING HEAD: IMPULSE CONTROL DISORDER Impulse-Control Disorder Impulse-Control Disorders Impulse-Control Disorder (ICD) is a repeated impulsive action that results in negative consequences. The DSM-IV distinguish five particular impulse-Control Disorder such as: kleptomania‚ pyromania‚ pathological‚ trichotillomania‚ and intermittent explosive disorder. The DSM-IV-TR named these five disorders “Not Elsewhere Classified” and names them separately

Analysis 1- Mirror neurons are cells that are actively firing both during a movement and while witnessing another perform the same movement. This can give insight into why sports fans get so worked up while watching a game. They are acting out; imitating what they see because the body is priming them. Their action neurons are firing just by watching‚ Kind of a monkey see monkey do scenario. The witnessing individual is adopting the other individuals’ point of view. 2- Mirror neurons contribute to feelings

Upper motor neurons and lower motor neurons act to carry nerve impulses from the brain out to the muscles in the body. Upper motor neurons supply input to the lower motor neurons. They do this by either synapsing directly to lower motor neurons‚ or by synapsing with a local circuit neuron‚ which then synapses with a lower motor neuron. The upper motor neurons originate in the motor region of the cerebral cortex or brainstem. The neurons from the cerebral cortex are important for planning‚ initiating

generally slows down everything but digestion. Signals from the SNS cause the heart rate to _________‚ while signals from the PNS cause the heart rate to ___________. Signals from the SNS cause smooth muscles of the intestine to _________ contractions‚ while signals from the PNS cause these muscles to _________ contractions. Signals from the SNS also cause the adrenal gland to _________ epinephrine and norepinephrine. 3. Neurons can excite or inhibit another neuron.

Neurons are cells used to perceive the outside environment‚ the internal environment within themselves‚ to formulate behavioral response to those signals‚ and to send that information to other neurons‚ muscles‚ or glands. All information comes into a neuron through the dendrite‚ flows through the neuron and then leaves to go to the next neuron through the axon. Neuron communication does not rely on a single entity but entrusts several different processes that involve the contribution of neuron structure

summation Summation can be defined as the method which neurons use to communicate with each other‚ determining if the cumulative postsynaptic potential in the neuron is enough to pass the threshold for firing. There are two types of summation‚ spatial summation and temporal summation. Both types of summation are similar in that they work to strengthen the EPSP of a neuron‚ meaning they help create more postsynaptic potential so that neurons are more likely to fire. Spatial summation and temporal
