SHEET NAME_____________________ LAB 6: Skeletal Muscle Physiology Electrical Stimulation 1. Complete the following statements by filling in your answers on the appropriate lines below. A motor unit consists of a (a) and all the (b) it innervates. Whole muscle contraction is a(n) (c) response. In order for muscles to work in a practical sense‚ (d) is the method used to produce a slow‚ steady increase in muscle force. When we see the slightest evidence of force

Prof. M.M.Mayuram FATIGUE CONSIDERATION IN DESIGN OBJECTIVES AND SCOPE In this module we will be discussing on design aspects related to fatigue failure‚ an important mode of failure in engineering components. Fatigue failure results mainly due to variable loading or more precisely due to cyclic variations in the applied loading or induced stresses So starting from the basic concepts of variable (non-static) loading‚ we will be discussing in detail how it leads to fatigue failure in components

First of all we have to defreniate between the musle stenght and muscles power. Musle stenght: Muscular strength defined as the ability of a muscle /group of muscles to contract with maximal force. Muscular strength describes how strong a muscle is or how much force it can exert. Exercise professionals often measure muscular strength by determining the maximum weight a person can lift at one time. There are 2 components to gain muscles strength; 1) The neural component (short-term). 2) The hypertrophic

Overview Patient is a 83 year-old female‚ presented to the ED on 7/2/13 with complaints of chest pain caused by what family believed to be aspiration pneumonia‚ also with worsening stage 4 sacral wound. Patient has a past medical history of a subdural hematoma secondary to a fall from a ladder‚ IDDM‚ bleeding gastric ulcer‚ and aspiration pneumonia. EKG and cardiac enzymes were ordered in the ED‚ EKG was unremarkable with a normal sinus rate and rhythm‚ enzymes within acceptable range. Patient sacral

Discuss the relationship between distribution of muscle fibre type and performance. How might exercise training modify or change a person’s fibre-type distribution? There are four different types of muscle fibres: type 1‚ type 2a‚ type 2x‚ and type 2c. “A single skeletal muscle contains fibres having different speeds of shortening and ability to generate maximal force: type 1 (slow-twitch) fibres and type 2 (fast-twitch) fibres. Type 1 fies take approximately 110 ms to reach peak tension when
