Unit 202 Safeguarding the welfare of children and young people Outcome 2 2.4A Describe the actions to take in response to emergency situations including: FIRES Regular testing of the fire alarms take place every six weeks at the School. The log book is kept by the business manager‚ this is available to any visiting fire officer. Fire instructions are clearly posted in all classrooms‚ offices and corridors. Also emergency exits are clearly signed. There are always at least 2 fire

INTRODUCTION I am going to explain the voluntary muscle the different types of muscle fibre including slow twitch fast twitch‚including how their properties are influenced by their reliance on aerobic and anaerobic energy sources. Skeletal muscle is made up of bundles of individual muscle fibres called myocytes. Each myocyte contains many myofibrils‚ which are strands of proteins (actin and myosin) that can grab on to each other and pull. This shortens the muscle and causes muscle contraction

LAB EXERCISE 2 THE PHYSIOLOGY OF SKELETAL MUSCLE (Martini p. 306-316) Work in groups of 4 Objectives: Name and describe the phases of a muscle twitch. Explain why the "all or none" law is reflected in the activity of a single muscle cell but not in an intact skeletal muscle. Understand that the graded response of skeletal muscle is a function of the number of muscle fibers stimulated and the frequency of the stimulus. Define and explain the physiological basis of the following: - subminimal‚

LABORATORY REPORT Activity 2: Twitch Contractions and Summation PREDICTIONS Effect of Muscle Fiber Length on Contraction 1. As muscle fiber length increases: contraction force increases‚ becoming maximum at an optimal length‚ then decreasing at longer lengths. Effect of Stimulation Frequency on Contraction 2. As the frequency of stimulation increases‚ the force of contraction: increases. MATERIALS AND METHODS Measurement of Threshold Stimulus 1. Dependent Variable: contraction force

Affirmative action is a policy that takes characteristics such as an individual’s race‚ sex‚ etc.‚ into account by a business (in terms of the hiring process) or government (in college admission affairs). Affirmative action presents itself in two forms; weak and strong. Weak affirmative action occurs when preference is awarded to a minority person with equal qualifications as their white‚ male counterpart; in a decision between a minority and white male of equal competence‚ the minority individual

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

In psychology and education‚ learning is commonly defined as a process that brings together cognitive‚ emotional‚ and environmental influences and experiences for acquiring‚ enhancing‚ or making changes in one ’s knowledge‚ skills‚ values‚ and world views. Learning as a process focuses on what happens when the learning takes place. Explanations of what happens constitute learning theories. A learning or practice theory attempts to describe how people and animals learn; thereby helping us understand

Date: Complete and current date Summary: According to the UN charter (Article 2‚ paragraph 4)‚ a multilateral treaty ratified by most countries‚ member nations cannot use military force except when it is needed to restore peace or when it is a self-defense tactic for itself and its allies. Preventive military strikes or preemptive strikes are not allowed except when it is obvious

this 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
