patient is admitted for electroconvulsive treatment (ECT). The physician orders the neuromuscular blocking agent metocurine iodide (metubine) to reduce trauma by relaxing skeletal muscles. Explain the process of muscle contraction and how a neuromuscular blocking agent‚ such as metubine‚ would interfere with muscle contraction. According to the Mayo Clinic website electroconvulsive treatment is the use of an electrical signal that sent through the brain to intentionally induce a brief seizure. They

of spontaneous contractions and the response to stimulating the nerves at 20 Hz with both a voltage that produced only a modest response and the voltage that produced the maximal response. 1) Briefly describe the response of the ileum when it is unstimulated and during stimulation of the nerves. It is shown that the rabbit ileum has a constant rate of contractions and relaxations‚ when it is not stimulated. However there is a significant drop in the amplitude of the contractions‚ when the ileum

Muscle building quickly is one goal a lot of body builders try to work hard on. As much as they also go for definition‚ shape and symmetry‚ these things are usually secondary for the goal of building muscle mass‚ at least for serious body builders. Most‚ if not all of them‚ adhere to the belief that having muscle mass is what separates a truly spectacular physique from the average person who just wants to flaunt an aesthetically nice and toned body. The first tip that people should take notice

What do you think it takes to make a muscle car? Is it foot/lbs of torque? Horsepower? Is it purely the image? The hype and build-up surrounding a muscle cars can get a little confusing when a new model is released‚ but the "tried and true" dream cars have proven their power and performance year after year and decade after decade. American‚ European‚ and Asian cars appeal to different segments of muscle car enthusiasts‚ for different reasons. Several cars immediately race into your thoughts when

the 70 ’s known as Muscle Dysmorphia (Mosley‚ 2009). It is defined as a continue obsession with muscularity (Olivardia‚ 2001). The majority of people that suffer from this disorder are bodybuilders – this was dominated by men but recently more women are practicing this kind of body shaping. Therefore‚ there were many athletes that developed the symptoms of Muscle Dismorphia that has been increasing (Leone‚ Sedory & Gray‚ 2005). Like every eating and body image disorder‚ Muscle Dysmorphia has several

Analysis: In this lab we measured the rate of respiration of germinating mung beans and germinating peas at room temperature and 10 degrees Celsius. The rates of respiration at room temperature were higher than the rates of respiration in cold water. The reaction rate of the germinating peas at room temperature was .0125 ml/min and the reaction rate of the peas at 10 degrees Celsius was .0095 ml/min. The same is true for the germinating mung beans. At room temperature the rate of reaction was .0105

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
