Amanda Fallon Professor Jed Wolfson Anatomy and Physiology 1 October 27, 2011 Rhabdomyolysis: Disease of Muscular Breakdown Rhabdomyolysis is the breakdown of damaged muscle tissues resulting in the release of muscle fiber contents into the bloodstream (Patel M.D.). This disease occurs when there is damage to the skeletal muscle. The breakdown products of damaged muscle cells, such as myoglobin, are harmful to the kidneys and frequently result in kidney damage or even kidney...

------------------------------------------------- LIST OF MUSCLE INJURIES Properly functioning muscles perform only one duty, contraction. Muscles enable the body to sit, to move and to stand upright. They are attached by way of tendons to bones. Their contraction is controlled by electrical signals that can either be voluntary, such as when a person decides to stand up, or involuntary, as with the muscles that expand and contract the chest to control breathing. Muscles are made of thousands...

Moral Muscle can be defined as pushing ourselves to do more than the minimum in our moral life. Moral Muscle is not just having physical strength but metal strength. The phrase Moral Muscle is a metaphor in which shows a type of strength someone obtains mentally. Someone who exercises his or her moral muscles has an mindset to do the right thing. Someone is considered to have moral strength when they restrict themselves from doing bad things and in place of that commit good thing. Moral...

Muscle Fatigue Monira Begum How muscles work and get the energy they need to work. Muscles need energy to work and move. (1) Their main source of energy is glucose. Glucose is made of a number of different types of carbohydrates (usually sugar) as well as milk and fruits. Glucose turns into other chemicals such as water and carbon dioxide which releases energy. (2)Your muscles get warm when using or burning energy. Glucose is sent to muscles through red blood cells; this is how muscles...

Question: How do various factors affect muscle fatigue? Introduction: In this experiment muscles will be tested with weight, to see if weight is truly a factor in muscle fatigue. Muscle fatigue is the muscle’s ability to contract exert its normal strength due to physical stress upon it. The structure of a muscle include a thin layer called epimysium which surrounds the entire muscle, deeper to the epimysium is the perimysium. This layer contains fascicles which are bundles of muscle cells. In...

Endomysium- covers the individual muscle fibers Sarcomere- smallest contractile element of muscle fiber, extends from z-line to z-line Myofilament- responsible for contraction Striated- the color variations on the muscle fiber. Has to do with the amount of protein and the way it reflects light. Myosin- globular protein Bulb like heads come in contact with the active sites on actin Active sites are not exposed when in the resting...

Q1 Muscle contraction can be understood as the consequence of a process of transmission of action potentials from one neuron to another. A chemical called acetylcholine is the neurotransmitter released from the presynaptic neuron. As the postsynaptic cells on the muscle cell membrane receive the acetylcholine, the channels for the cations sodium and potassium are opened. These cations produce a net depolarization of the cell membrane and this electrical signal travels along the muscle fibers....

 MUSCLE FATIGUE HOW DO MUSCLES GET THE ENERGY TO WORK? In muscles, it is essential that Calcium is present, as this gives the muscles the ability to contract and relax. For muscles to contract energy is needed: the energy can only be provided by the breakdown of a chemical called adenosine triphosphate (ATP). As ATP is broken down, a phosphate molecule is broken off, reducing the phosphate molecules, from 3 to 2. This produces adenosine triphosphate. However for the muscles contraction to...

 Muscle spasms are involuntary contractions of muscles that are often very painful. Muscle spasms are also called cramps or referred to as a “Charley horse”. These contractions are most frequent on the leg muscles but can also occur in the hands, arms and abdomen. (www.webmd.com) Typically the muscles become very hard and tight. There are many causes of muscle spasms. The most common cause is overuse during athletic activities such as sports or general exercise. Other causes...

Air Muscles Introduction Pneumatic actuators, usually cylinders, are widely used in factory floor automation. Lately, robotics as well is starting to use pneumatics as a main motion power source. One of the major attractions about pneumatics is the low weight and the inherent compliant behavior of its actuators. Compliance is due to the compressibility of air and, as such, can be influenced by controlling the operating pressure. This is an important feature...

There are four types of tissue found in animals: connective, muscle, nervous, and epithelial. We are going to go into muscle tissue. The cells of muscle tissues are called fibers. There are three types of muscle tissue and they are skeletal, cardiac, and smooth. All types can go though hypertrophy (enlargement or overgrowth of an organ or part of the body due to the increased size of the constituent cells). Muscle fibers contract due to the interaction of the contractile proteins, actin and...

We will only be...

Muscle Soreness Nearly anyone who works out regularly has experienced sore muscles after exercise. Sometimes you will feel it later that night, or the next morning and in some cases, you may actually think you are out of the woods, only to wake up two days later with stiff, tender muscles that feel as tight as rubber bands. For some people, sore muscles are a reward after a hard workout. In fact, some people are not happy unless they are sore after their workout, while others could live...

People have their own thought process when it comes to fitness and getting in shape. Everyone has their own specific goals in which they are trying to accomplish. Today I am going to talk about how BUILDING MUSCLE INCORPORATES MANY DIFFERENT FACTORS BUT CAN ULTIMATELY BE ACHEIEVED BY NUTRION, WEIGHT TRAINGING, AND ADDING SUPPLEMENTS TO YOUR DAILY ROUTINE.

Muscle fatigue is weakness or weariness resulting from exertion or prolonged stress and the failure to maintain an expected power output. (Amussen) The process by which your body produces energy is called glycolysis. During glycolysis, glycogen is broken to produce creatine phosphate, which releases energy. The energy released catalyzes a reaction to produce ATP. The ending product of glycolysis is lactic acid, which is created by breaking pyruvate acid down. Then lactic acid is broken down to...

Jeni Hewitt English 101 Mr. B 17 March 2013 Do you exercise? Obviously exercise is important and has many benefits. When the word exercise is mentioned, what comes to mind? Some people believe that exercise is more of a health and heart thing. Some believe exercise is more for appearance and the way one looks. While others believe exercise is for psychological reasons.

Introduction Jan Swammerdam, who demonstrated that an isolated frog muscle could be made to contract when the sciatic nerve was irritated with a metal object, conducted the first muscle experiments between 1661 and 1665. Later, between 1737-1798 Luigi Galvani determined that frog muscle responded to electrical currents. The kymograph, which was invented in the late 1840’s lead to the revolution of experimental physiology because it enabled muscle contractions to be analyzed and recorded. The...

Dietary Factors Controlling Healthy Development Of Muscle And Bone. The food you eat affects every system and function in your body. A well-balanced diet ensures that your body has the raw materials to produce and maintain healthy, strong muscles and bones. On the other hand, poor dietary habits can produce deficiencies in vital nutrients, leading to poor bone and muscle development in children or the damaging of the body's ability to maintain strong muscles and bones in adults. Protein...

Viany Reyes November 08, 2011 Dr. Dunaway Neuronal signaling in muscle contraction is triggered when an action potential reaches the neuromuscular junction. At this junction, acetylcholine (ACh) is the main neurotransmitter. Packaged in vesicles, ACh fuses with the neuron’s membrane and is released into the synaptic cleft. ACh diffuses toward the motor end plate and bind to the neurotransmitter receptor on it. The muscle fiber is then triggered to produce an action potential of its...

 1-Why do skeletal muscles enter in a contracted state called “rigor mortis” a few hours after death and last for up to 72 hours? Skeletal muscle enter a contracted state called rigor mortis because the skeletal muscles are only able to partly contract. The muscles are not able to relax, so the joints are fixed in place. Rigor mortis can be used to help estimate the time of an individual’s death. The onset of rigor mortis may range from ten minutes to several hours. Maximum stiffness is...

Anatomy of Muscle Cells There are three types of muscle tissue in the human body. These muscle tissues are skeletal muscles, smooth muscles and cardiac muscles. Each of these muscle tissues has it very own anatomical makeup, which vary from muscle to muscle. The muscle cells in a muscle are referred to as muscle fibers, these fibers are skeletal muscle fibers, smooth muscle fibers and cardiac muscle fibers. The anatomy of a skeletal muscle fiber is formed during embryonic...

How to Build Muscle 1. Develop a Technique Learn the proper way to do each exercise whether it is pushups or weight training. Developing a solid technique will maximize the workout and strengthen the muscles. Strength training is a method that should not be overlooked because it allows a person to start with minimal weight and add more weight as they progress. This builds more muscle which in turn builds more strength. 2. Machines vs. Free Weights Those weightlifting...

It is understood that the term process involves more than one step to achieve an end result. The process of bodybuilding is exactly that, a long disciplined process. There is one main goal in the sport of bodybuilding and that is to gain lean muscle mass. To go about this, you need three aspects and goals to resound in harmony in order to successfully achieve your body composition goals. A proper diet to put on muscle and lose fat, a vigorous and consistent training regimen, proper rest, and...

How to “bulk up” properly for bodybuilding Have you ever wondered how to gain the muscle without gaining a lot of body fat? Here I will explain to you why bulking is of substantial importance in the sport of bodybuilding. I will inform you on what kind of a diet you should follow, when to bulk, the training that goes along with it, and proper rest to ensure that you get maximum muscle growth. Most bodybuilders bulk up to gain size, muscle and strength. If I wanted to compete even at the...

Muscle Change in People Anatomy and Physiology Professor Debra Low Discussion Board Stephanie Quinn March11, 2013 Which lower extremity muscles are utilized during standing and walking? They are your Quadriceps they are the biggest muscles by far they are at the front of the thighs. They raise the thigh and leg. Then there are the Hamstrings these form the back of the thighs and move the leg backward. The Buttocks powerful and bulky complete the backward movement of the step. Stomach...

Notes on histology Histology Lecture 1 Histology is the study of tissues: in our case, it means study of tissues which make up the human body. Tissue is defined as a group of cells which perform a common function. All the cells in a given tissue are not necessarily identical or similar e.g. blood is a type of connective tissue but it has many different types of cells. However, tissue also contains two other components i.e. ground substance (or matrix) and fibres. Despite the complexity...

1. Based on the results of your investigation, what conclusions can you draw about the relationship between a muscle's workload and its threshold of stimulation? The conclusions I was able to determine about the muscle’s workload and its threshold of stimulation was that the threshold stimulus will increase by one when the workload doubles. The muscles can hold a higher workload if they originally have a higher threshold of stimulation with no workload at all. 2. Why would a muscle's...

The musculoskeletal system is made up of bones, joints, and muscles. This system gives the body form and support, and protects the body while allowing it to move. Basically, the muscles in this system perform three important body functions: the movement of body parts, maintenance of body parts, and production of body heat. These muscles all consist of a mass of protein fibers grouped together, and most are of mesodermal origin. And almost all of the muscle fibers you will ever have or need...

I. Contraction of Quadriceps Muscle and Extension of Leg Abstract1 The purpose of the Patellar reflex lab was to observe the effect of central nervous system influence on reflex amplitude. My hypothesis was a reflex with reinforcement would have a greater Max of (mV). In this lab we attached three electrode tabs to the leg and connected them to a EKG Sensor. Next we swung a reflex hammer in contact with the patellar tendon and observed the results without reinforcement and then with...
