occur. At the start my lab partner was calm resulting in the blood pressure to be around 125/59 with 55 beats per minute. The second time we did it‚ the numbers were fairly similar 126/59 and 62 beats per minute. At the beginning there is no action potential occurring or the pacemaker is not racing to make the heart beat quicker because the body is not using much energy since it is basically at a resting state. You can detect the heart beats by using the QRS EKG method where each one can represent a

Regenerative Braking Regenerative braking is used on automobiles to recoup some of the energy that is lost while the vehicle is stopping. This technology is used on hybrid vehicles that use both gas and electricity as sources of power. The energy that is recouped during braking is saved in a storage battery and used later to power the motor whenever the vehicle is using its electric power source. Conventional Braking Systems In braking systems on conventional vehicles‚ friction is used to counteract

In order to determine the role of the amacrine cells they needed to determine the method of bipolar convergence and divergence in ganglion cells. When stimulated individually‚ two different bipolar cells were able to elicit distinct post synaptic potentials in the ganglion cell. Whether a transient or sustained response was to be fired was determined right at that connection (Asari and Meister‚ 2012). In this way‚ the bipolar cell acts similar to the controller (Carpenter and Reddi‚ 190) in a motor

Energy is measured in joules‚ (J) or kilojoules (kJ) Energy exists in many different forums such as Kinetic and potential energy – Kinetic energy is the movement of energy and potential is stored energy‚ energy ready to go. A lawn mower filled with gasoline‚ a car on top of a hill‚ and students waiting to go home from school are all examples of potential energy. Gravitational potential energy is the energy crazed by a body because of its elevation relative to a lower elevation‚ that is‚ the energy

Science Notes: Fundamental Forces of Nature All forces in nature may be classified into four types. The gravitational force holds together the universe at large‚ plus the atmosphere‚ water‚ and us to the planet Earth. The electromagnetic force governs atomic level phenomena‚ binding electrons to atoms‚ and atoms to one another to form molecules and compounds. The strong nuclear force holds the nucleus together. The fourth force‚ the weak nuclear force‚ is responsible for certain types of nuclear

neuronal action potentials. Sodium channels open‚ increase of sodium INTO cell. Phase 1- sodium channels close‚ potassium channels close‚ decrease in potassium and sodium. Calcium channels open‚ increase of calcium into cell. Phase 2- Plateau phase‚ membrane still depolarized (contract). Potassium channels closed‚ L-type calcium channels stay open. Lasts 0.2 seconds/200 milliseconds. Phase 3- second set of potassium channels open‚ potassium decrease. Failing membrane potential cause calcium

terms depolarization and action potential mean the same thing? The terms depolarization and action potential differ because are excitable cells that communicate by transmitting electrical impulses that are capable of producing rapid electrical signals and depolarization in the interior surface of the membrane which becomes less negative and the exterior surface becomes less positive. Additionally‚ when depolarization reaches a certain threshold‚ an action potential is initiated and the polarity

these factors either in isolation or in combination with one another that influence how much work the river can do. A river flows downhill due to gravity and this gives it 2 types of energy - potential and the higher above sea level the river is the more potential energy it will have and kinetic energy‚ which is generated by the actual movement of water as it travels down slope. Many factors influence how much energy a river has and therefore how much work it can do. A river

hundreds‚ even thousands of other neurons. Each signal is either excitatory or inhibitory. Excitatory signals increase the likelihood of an action potential happening‚ inhibitory make an action potential in a nerve cell less likely. The action potential is a nerve impulse. Once the excitatory signals over power the inhibitory signals and action potential is triggered. So the neuron then fires‚ sending that impulse down its axon‚ transmitting information to another cell. The firing of a neuron isn’t
