Excitatory postsynaptic potential

(The nervous system Louisa Idzal) The nervous system is all connected because it’s a web of nerve cells and fibers that all send nerve impulses throughout and between body parts. The nervous system is really important because it’s in charge of sending messages to the spinal cord and brain to and from all parts of the body. Main organs of the nervous system are Nervous Tissue, Brain, Spinal Cord, Nerves, Sense Organs, and the Cerebrospinal Fluid. The nervous tissue is the main tissue of the…

1. What energy system(s) does the Wingate Test rely? Explain. The energy systems that the Wingate test relies on, is glycolysis and ATP-PCr. Anaerobic power is used for high intensity, short duration exercises, and activities. The Wingate test is anaerobic, which will utilize fuel through glycolysis and the ATP-PCr system. The Wingate test is very short in duration, and high in intensity, which means oxygen is not present in this process. The ATP-PCr system breaks down ATP into ADP for energy.…

surface at an angle, the more potential she will have for flips. You can find a gymnast’s angular momentum with the formula: L = (r)(m)(v). By analyzing the equation, you can determine that, while the mass (m) and angular momentum (L) are considered a constant, lowering the distance of the body from the axis of rotation (r), will lead to an increase in velocity (v), this velocity allows for the gymnast to attain the maximum amount of force, leading to more potential for twists and flips while in…

spatial summation (Maler and Rogers 1981). It will not fire upon input from only one T unit, it must receive synchronous input from various T units converging at the spherical cell at the same time (Maler and Rogers 1981). When this occurs, an action potential is generated. This was determined by a clever experiment in which, a fish was administer just enough anesthesia to disable its EOD (Maler and Rogers 1981). The researchers replaced its EOD with one that they produced and were able to…

Name: Institution: Course: Instructor: Date of Submission: Pendulum and spring Abstract In this lab, two systems namely a pendulum and a spring that exhibit simple harmonic motion were studied. The systems were subjected to a mass of known weight and allowed to oscillate. Afterwards, the period of each was determined. In addition, the harmonic properties in the systems and their limiting factors were determined through quantitative calculations. Introduction Any system that exhibits back and…

The authors created the Accelerated Sensor of Action Potentials 1 (ASAP 1) using a green fluorescent protein source on the extracellular side of the plasma membrane to highlight the membrane potential changes as demonstrated by the fluctuation in the fluorescent brightness. Neuronal action potentials generated are monitored up to 200 Hz in frequency using this device. The general purpose of this experiment was to further understand information processing in the brain and how brain activity is…

The brain is an organ that serves as the center of the nervous system for most living things. There are only a few animals that do not have a brain like starfish or jellyfish. The brain is located in the head. It receives messages from other organs. The brain is the most complex organ. In a human, the cerebral cortex has more than a billion neurons. Each of these neurons are connected by synapses. These synapses are connected to several thousand other neurons. Neurons communicate with one…

Figure 1. An EMG Tracing of Triceps and Biceps Muscles Co-activation. EMG signal produces an electrical activity of the muscle fibers active at a moment time. The electrical activity is measured in millivolts per milliseconds. The top channel shows the bicep EMG, while the bottom EMG correlates to the triceps contraction traces. Shown on the top graph, there are two periods of bicep activation, each last approximately 1.5ms. When the biceps are activated, it produces increasing amplitude peaks,…

violently making it difficult to determine when the car reached each location. As the car went through the track, going up into the loops it grew in height, decreasing in kinetic energy while increasing in potential energy. This caused a greater energy loss due to the significant amount of potential energy transferred into kinetic energy. For example, the inverted curve follows after the lowest point in the roller coaster, which increases the height. This acts…

resistance is common. Stability is evident when adding toxins for selective pressure ensures that only the stable ones can proliferate in further cultivations10. In this experiment, we use the Geneticin (G418) toxin agent for isolating drugs with potential antagonism. G418 inhibits polypeptide synthesis (400 μg/mL is recommended). G418 resistance involves the addition of a Tn5 gene that encodes for an…
