Excitatory postsynaptic potential

Abstract The value for the acceleration of gravity was measured in this report through the investigation using three different methods, each varying in accuracy, to calculate the period of a pendulum. The period was measured by repeatedly timing the time it took for the pendulum to return to its original position once it was swung from a certain point (for the first method one oscillation was timed, however in the second and third ten oscillations were timed and the overall time was divided by…

action. In a neuron, it first has to have a certain amount of depolarizing ions for there to be an action potential. When that action potential is reached, charge can be sent through the axon (which is protected by the myelin shealth). As a charge goes through a neuron, vesicles that hold neurotransmitters (that are contained in the presynaptic terminal button) can be then released to the postsynaptic spine. After traveling across a small space that separates neurons (synaptic gap) dendrites on…

example of gravitational potential energy changing to kinetic energy. Potential energy can come in many forms. For example, chemical energy can be stored and later converted into heat or electricity.…

Discuss the relationship between energy and society. The principle question to ask when examining the relationship between energy and society is whether society drive changes in energy or energy stimulates societal change. The most common answer is that as society innovates and grows more forms of energy are harnessed and so our use of energy changes. However, at a more fundamental level, every major change in human history has been caused by the availability of energy in its various forms. The…

This study analyzed the differences and the relationships of the isolated sciatic nerve in regards to the compound action potential and the neuromuscular junction stimulations of the Rana pipens gastrocnemius. A total of five exercises were used to identify the effects on the stimulation of the sciatic nerve and the gastrocnemius. A dissection for both labs were performed to isolate the nerve and to isolate the gastrocnemius. Both experiments used LabChart to perform various stimulations on the…

another neuron. The synaptic gap does not come in contact with one another. The area where the neurotransmitters are released is called the presynaptic gap and the area where the neurotransmitters come in contact with the dendrites is called the postsynaptic gap. (Pastorino and Doyle-Portillio, 2015). In the case of answering the cell phone, the neurotransmitter that will be released is acetylcholine, a neurotransmitter that excites skeletal muscles and provides movement (Pastorino and…

can not be created or destroyed only converted into different forms and traded between systems. All energy is measured in Joules (J). When we talk about waterfalls and dams, the energy’s original form is Gravitational Potential Energy (GPE) which is energy that comes from the potential all objects have to move due to gravity when they are not on the surface of the Earth. The GPE of an object is just the relationship between the object’s mass, the acceleration due to gravity which is a…

Hydropower is power that is generated from a dam by making water fall from a certain height behind the dam to a power plant that is lower in height. As a result, the water behind the dam has gravitational potential energy, which is converted to kinetic energy as it falls to the power plant. The power plant uses its turbines to convert the kinetic energy to electrical energy. In this assignment, we are figuring out “to what extent can hydropower meet the electrical energy needs in the United…

neurotransmitters) into the synaptic cleft (7, 8), the area between pre-synaptic membrane and postsynaptic membrane of the subsequent neuron. Chemical neurotransmitters diffuses across the synaptic cleft and travel towards the post-synaptic membrane of the target cell in less than a millisecond. Neurotransmitter then binds to the highly specific receptor sites on the post-synaptic membrane. The binding changes the potential or electrical…
