Lab 6 Biomechanics of Frog Skeletal Muscle I. Purpose This exercise is designed to demonstrate some mechanical and physiological properties of skeletal muscle using the gastrocnemius muscle of a frog. II. Performance Objectives At the end of this exercise the student should be able to: 1. Define minimal (threshold)‚ subminimal‚ maximal‚ and supramaximal stimulus. 2. Explain what is meant by a “graded” response. 3. Draw a diagram of the setup used in this lab exercise. 4. Calculate the

Abstract The purpose of this experiment was to use the muscle tension and the electrical activity in the dominant and non-dominant forearm muscle‚ the flexor digitorum superficialis‚ to analyze the determinants of muscle tension and fatigue‚ and the reasons as to why differences may occur between the dominant and non-dominant arm. The generation of tension in a muscle is determined by the major type of motor unit being recruited‚ as well as the rate in which action potentials are being fired. A subject

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. It is generally accepted that muscle fibre

ANATOMY AND PHYSIOLOGY The pelvis is a large semicircular bone complex that forms the base on which the torso and upper body are positioned. The pelvis‚ which is a rigid and inflexible portion of the skeleton‚ is built to provide a foundation of the movement of other parts of the anatomy‚ particularly the back and the legs. The pelvis also permits the weight of the entire upper body to be evenly distributed

INTROduction TO THE HUMAN BODY 1. Define anatomy and physiology While anatomy provides us with a static image of the body architecture‚ physiology reveals the body’s dynamic and animated workings. Physiology often focuses on events at the cellular or molecular level. A. Anatomy – studies the structure of the body parts and their relationship to one another. i. Developmental – concerns structural changes that in the body occur throughout the lifespan. Embryology studies the developmental changes

Unit 5: Anatomy and Physiology (P4) Explain the physiology of two named body systems in relation to energy metabolism in the body In this task I am going to discuss the three systems involved in energy metabolism in the body. The chemical equation for cellular respiration is: C6H12O6 + O2 = E + CO2 + H2O OR Glucose + Oxygen = Energy + Carbon Dioxide + Water In order to release energy we need glucose which is a simple carbohydrate that is produced after digestion of food and we also need oxygen

INTRODUCTION An electronic muscle stimulator is a circuit designed to stimulate nerves of that part of the body by attaching electrodes. It is used to revive frozen muscle that impair movement‚ it aid in building up muscles and it also helps in removing cellulites in the body EMS causes adaption‚ i.e. training of muscles fibers and can be used as a therapeutic tool. In medicine it is used for rehabilitation purposes‚ for instance in Physical therapy in the prevention of disuse muscle atrophy which can

valuable when additionally talking about weakness. A basic thought to recollect is that muscle compression is because of a particle called ATP (adenosine triphosphate). ATP must be available for muscles to contract. There are three frameworks of energy that create ATP: Phosphocreatine system‚ the glycolytic system‚ or the oxidative system. On the off chance that exhausted‚ it must be renewed if additional muscle withdrawal is to proceed. Since we are talking about ATP Pathways‚ I needed to additionally

Muscle Strain Overview- Muscle strain‚ also termed as muscle tear and muscle pull is related to the muscle damage and its attached tendons. It occurs when you give excessive pressure on muscles during performing daily life activities like during sports or heavy weight lifting.it can be in the form of tearing of the fibres of your muscles and attaching tendons. In addition to this it also affects small blood vessels which leads to bleeding‚ bruising and pain. Causes- A severe muscle strain occurs
