Activity 4: Generation of Action Potentials Name: Instructor: Date: PREDICTIONS 1. Exceeding the threshold depolarization at the trigger zone DECREASES the likelihood of generation of action potential. 2. Action potential amplitude: DOES NOT CHANGE with distance 3. Increasing frequency of stimulation to the trigger zone: DOES NOT increase the production of action potentials. MATERIALS AND METHODS Experiment 1: Effect of Stimulus Strength on Action Potential Generation 1. Dependent Variable

When a ball is dropped/ thrown to the ground‚ gravity forces the ball to move downwards‚ whilst the ball falls down‚ the Gravitational Potential Energy (GPE) that the ball has transforms into Kinetic energy. As the ball hits the ground with maximum Kinetic energy‚ the forces in play flatten and deform the frame/shape of the ball by compressing and dispersing the molecules that essentially make up the ball. As stated in the law of conservation energy‚ energy can neither be created nor destroyed; rather

applying a net force‚ the object speeds up and thereby gains kinetic energy(Kinetic Energy) which will make my car go further. This illustrates how if there is more potential energy than kinetic energy the car won’t go nearly as far as it could. According to my research‚ potential energy is stored energy that is waiting to be used(Potential Energy)‚ so that means

Potential Energy: Potential energy is the stored energy of position possessed by an object. Potential Energy Formula : Potential Energy: PE = m x g x h Mass: Acceleration of Gravity: Height: where‚ PE = Potential Energy‚ m = Mass of object‚ g = Acceleration of Gravity‚ h = Height of object‚ Examples: 1. A cat had climbed at the top of the tree. The Tree is 20 meters high and the cat weighs 6kg. How much potential energy does the cat have? m = 6 kg‚ h = 20

measured through the amount of gravitational potential energy that the tennis ball had before it was dropped‚ and by the amount of work it had done when displacing the sand. As shown in Table 2‚ when the tennis ball was dropped at a height of 1 meter‚ it only possessed a potential energy of 0.569 J. When dropped from 5.5 meters‚ it held a potential energy of 3.217 J. This shows a positive correlation between the height of the drop and the amount of potential energy the tennis ball had. Also‚ shown in

experiment was to examine how the compound action potentials propagate down the sciatic nerve of a frog based on varying stimuli. Before the nerve could be tested it needed to be extracted from the thigh of the frog and then submerged in saline. Several varying stimuli were used and recorded by a software package. The second experiment requires a constant stimulus with varying reference pin locations. From this the velocity of the action potential propagated can be determined. The experiment revealed

and objectives: to integrate knowledge‚ theory and practice‚ to develop and apply a broad knowledge and skills and to have an individual patient/client focus in my practice. To achieve all of the above I am required to complete project in a form of Graded Unit which consists of three stages: planning‚ development and evaluation. After consultation with my work experience mentor and lead lecture (appendix 1 and 2) it was agreed‚ the project will be a nursing activity‚ weighing a patient ‚ which will
