Animal Phyla Lab Adapted from “Phylum Lab” produced by the National Aquarium in Baltimore The diversity of animal life on Earth is astounding. Each animal has a unique body plan which allows it to survive and adapt to its given surroundings. With such an abundance of species‚ classifying animals into different categories is necessary. At first the diversity of animals can be overwhelming‚ but after further research and observation‚ many likenesses appear. These similarities become the basis for

Introduction/Lab Description This lab is meant as an introduction to properly instructing individual stretches. (40 points) Objectives 1. Identify the joint movements and muscles being stretched during a variety of stretches. 2. Describe and demonstrate proper technique (e.g. range of motion‚ body positioning‚) for a variety of generally safe and effective stretches to enhance flexibility. 3. Demonstrate the ability to teach common stretches using proper directions‚ cueing‚ and

we begin to experience the damages and pain we created for ourselves during our more youthful years. There are a number of factors that can make us more susceptible to bone disease. In this paper I will be discussing Osteoporosis‚ Osteoarthritis‚ Muscle Atrophy and the effects they would have on an eighty year old woman. The women’s physical condition is thin‚ small boned‚ and is Caucasian. None of these characteristics are in her favor of making her less likely to fall victim to the above bone or

length-tension relationships represent an important part in the function of skeletal muscle. When skeletal muscle is stimulated‚ passive tissue rapidly changes into dynamic tissue which can produce force. Furthermore‚ during this process‚ the length of muscle may decrease‚ increase‚ or remain the same. Moreover‚ the amount of power a muscle can produce depends on its length‚ velocity and stimulation Powers & Howley (2015). Muscle velocity and stimulation are normally in a constant when creating a length-tension

Have you like me tried to build and gain muscle ‚ or maybe you just looking for a bit more info on the subject. Building muscles are not really easy but if more effort is devoted to muscle building in no time we can gain the type of muscle we want.To build muscle fast requires a muscle building workout plan.I could remember when i tried muscle building without any workout plan‚i had muscle pull for 1 week‚i felt pains all over me to the extent i couldn’t move some parts of my body because of this

A 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

INTRODUCTION Smooth muscle fibers in different organs are distinctly different from each other in their physical dimensions‚ organization into bundles or sheets‚ response to stimuli‚ characteristics of innovation‚ and function. Smooth muscle is responsible for the contractility of hollow organs‚ such as blood vessels‚ the gastrointestinal tract‚ the bladder and the uterus. Specifically in the uterus‚ regulation of smooth muscle contraction is under the influence of an octapeptide known

INTRODUCTION OF MUSCULAR SYSTEM. Muscles tissue do is done by the coordinated contraction and release of millions of sarcomeres‚ tiny structures within the muscles cells. Muscle activity accounts for the most of the body’s energy consumption. All muscles tissues is strong. Most is enduring‚ some of it astoundingly so. Its cells are crowded with mitochondria‚ thousands of little factories constantly turning out molecules of ATP‚ a refined fuel. There are three types of muscles that can be found in our body

certain task. In this lab we examined motor unit recruitment and muscle fatigue by electromyography (EMG) with dynamometry (DYN). When the motor unit in the muscle is activated signals are then generated‚ which result in muscle contraction. The impulse generated are a bit weak‚ yet can still be detected by the electrodes‚ EMG and is coupled by a measurements of power‚ DYN. When all the motor units reach its maximum strength the muscles will fatigue. Finally‚ the objectives of this lab were to determine
