Electric potential

specifically designed to start and distribute electric impulses through the cardiac cells so that depolarization and contractions are orderly and sequential. The contractile cells sustain stable membrane resting potential when they are unstimulated, however, the resting potential of the autorhythmic cells, that create the intrinsic conduction system, is unstable and is constantly depolarizing, which is called pacemaker potentials and initiate the action potential that causes the heart to contract (Marieb

The nervous system has three general functions: a sensory function, an interpretative function and a motor function. Sensory nerves gather information from inside the body and the outside environment. The nerves then carry the information to central nervous system (CNS). Nervous tissue consists of two main types of cells: neurons and neuroglia. Neurons also so known as nerve cells ") transmit nerve impulses that move information around the body. Central Nervous System and Peripheral Nervous System

biphasic compound action potential, both the positive and negative recording electrodes were used, with the negative recording electrode at position ‘D’ and the positive recording electrode at position ‘E’ (refer to Figure 1). The extracellular bipolar recording takes the difference between what the negative electrode picked up and what the positive electrode picked up. The first, positive deflection of the CAP was caused by the extracellular negative charge of the action potential recorded by the negative

Use of BCI in making ANIMATED Movies Brain Computer Interface: Brain computer Interface is connection between brain and computer or other external devices. It enables to do external activities such as control of cursor or moving artificial hand. (wikipedia)  How nerves work Brain is the center of nervous system, like a micro processor in computer. Spinal cord is connected with nerves as gates are connected with wires in the computer. Nerves carry signals to coordinate different parts of bodies

from the synapse. The electric impulse move from the first neuron, along the axon, to the synapse at the synaptic knobs. Secretion of chemical transmitter into the synaptic nerve depolarizes the membrane of the subsequent neuron. In its unexcited state, a neuron retains a resting membrane potential. When the membrane potential is excited, the arrival of an action potential at the synaptic knob allows the neurotransmitters released into synaptic cleft to trigger an action potential in the postsynaptic

define each as a physical material can be relatively difficult. To continue, energy can neither be created nor destroyed but exists in two forms – potential and kinetic. Feyman et al. (2013) reported that potential energy is the capacity for doing work based upon the body’s position in space. In this situation, an object will have a certain amount of potential energy based upon its location in reference to a gravitational field. This notion is true in and outside of Earth, given that the movement of objects

A Key Component to our Energy Needs Introduction Renewable energy is without a doubt the solution to the worlds energy needs. As time progress as does the technology avaiablible to us. With this advancing technology we have seen some major strides made in the area of renewable energy. As you are most likely aware the main renewable energy sources are Wind, Solar, and Hydroelectricity. With the rising awareness of the affects fossil fuels has on our environment the time to act is now. All forms of

Many processes go on in your body before you complete an action as simple as turning a page over. These processes take place in a matter of milliseconds from the start of you visualizing turning over the page to the actual completion of the action of turning the page over. Notably, it starts with your eyes. Your eyes are looking at the page you are about to turn over, they are taking in this information on how the paper looks in front of you and is sending it as light coming in through

of potential energy to kinetic energy using a model roller coaster track? II. Background Research Did you ever wonder how a roller coaster works? Why does one roller coaster go faster than another at certain points on the ride? This paper will discuss how potential energy turns into kinetic energy at different points along the track of a roller coaster. The important terms that will be discussed are potential energy (stored energy), kinetic energy (energy of motion), gravitational potential energy
