  • Cardiac Muscle Tissue Analysis

    1727 Words  | 7 Pages

    It is known simply as cardiac muscle tissue. The name may be simple, but cardiac muscle tissue is anything but simple and it deserves an entire section on its own. Cardiac muscle tissue is striated much like skeletal muscle tissue, but is different in that cardiac muscle fibers are shorter and exhibit a “branching” appearance (refer to figure 1.2). Cardiac muscle fibers are also similar to skeletal muscle in that they contain all of the same arrangements of actin

  • Cardiac Muscle Case Study

    Section A – Part II Cardiac cycle or heartbeat Blood enters and fills both atriums at the same time. When full the pressure causes the tricuspid and bicuspid valves to open and flows into the ventricles. Contraction (systole) of each atrium now forces any remaining blood into the ventricles. The ventricles now contract (systole) and atriums relax (diastole). The pressure closes the tricuspid and bicuspid valves (causes the first sound of the heart beat). The contraction of the ventricles opens

    have formed into cardiac patches containing beats throughout, it is time to create a heart outline. Since the cardiospheres fused successfully, I believe that when many of these patches are made, they all can be aligned in the shape of a human heart, so the many patches can all fuse as one. To successfully do this, I will be using a technique where half of the heart will be made using an outline by covering it with these patches for them to mature into strong multicellular cardiac tissues. An outline

  • The Heart Research Paper

    999 Words  | 4 Pages

    The heart is one of many vital organs of the human body. To be more precise, the heart is a muscle about the size of a fist, that never rests (unless the person is dead) from working for the body. The purpose of the heart is to circulate oxygen carrying blood to parts throughout the human body, feeding the cells and keeping the person alive. The heart circulates blood by “pumping” the blood throughout the body, noticeable by the beating. The process goes as follows; oxygen and nutrient deprived

  • Annex 1 Heart Murmur

    951 Words  | 4 Pages

    blood flows across one of the heart (valves, cardiac chambers) and or vessels close to the heart Heart murmurs are classified by the intensity of the sound heard: Stage I (murmur is of low intensity and can hardly be heard) to Stage VI (murmur is extremely loud). Cardiac murmurs can be present at birth (congenital; often caused by malformations) or acquired and manifests later in the animals life. (Ex: disease of the cardiac muscles, disease of the cardiac valves, etc.). It is important to note that

  • The Human Body: The Circulatory System

    900 Words  | 4 Pages

    The organs are made up of tissues working together, such as the smooth/cardiac muscle tissues and blood. The tissues are made up of different types of cells working together, such as red and white blood cells, along with smooth/cardiac muscle cells. Therefore it can be concluded that the circulatory system is composed of groups of cells. All of the other organ systems throughout the body are also made

  • Muscular Dystrophy

    971 Words  | 4 Pages

    Muscular dystrophy is a group of muscle diseases that weaken the musculoskeletal system and hamper locomotion. Muscular dystrophies are characterized by progressive skeletal muscle weakness, defects in muscle proteins, and the death of muscle cells and tissue. In the 1860s, descriptions of boys who grew progressively weaker, lost the ability to walk, and died at an early age became more prominent in medical journals. In the following decade, French neurologist Guillaume Duchenne gave a comprehensive

    Muscles are essential for life. There are three types of muscles. Cardiac, smooth, and skeletal. Four key characteristics for muscles are excitability, contractility, extensibility and elasticity. Excitability pertains to a muscles’ ability to respond to stimuli. This is important for external and internal changes in the body. Contractility is the ability to shorten when sufficiently stimulated. Extensibility is the capability to stretch or extend. When being contracted, muscle cells shorten; but

  • Musculo Skeletal System Research Paper

    The musculo skeletal is made of bones, muscles, ligaments and tendons. The purpose of the musculo skeletal system is to protect , support and the overall function of the internal structures and organs of the body. Allow movement, give shape to the body, producing blood cells, storing calcium and phosphorus and producing heat. The skeletal system is made of bones and joints. The skeletal system provides the basic supporting structure of the body. It is made of the joined frame of bones called the

    mass of tissue extending from the sternum down to the vertebral column between the lungs. Structurally, the heart is composed of three layers of tissue; epicardium, myocardium (middle layer) and endocardium (inner layer). The epicardium is a layer of muscle composed of mesothelium and connective tissue sheltering the external surfaces of the heart. This external layer is directly merged with the myocardium internally and is in contact with the serous layer of the pericardium. In some cases, it is viewed

    The Musculoskeletal System The Musculoskeletal system is made up of muscle, bones, tendons, cartilage, ligaments, nerves and other connective tissues. The main purpose is to support and stabilise the body. The bones work together with the muscles to allow controlled movement and to keep the body’s shape. The bones of the body provide five main functions they are to produce blood cells (white and red), protect body organs (brain, lungs), provided leverage and movement (so we can sit up), and store

    weakness and generation of the skeletal muscles that control movement. The patient has to undergo “clinical examination and laboratory procedures, including electromyography, muscle biopsy, DNA analysis and selected enzymes levels assayed from blood samples” (Campbell, Palisano 2006). The most common form of muscular dystrophy occurring in children is Duchenne Muscular Dystrophy amongst other prevalent types (Table 1). The focus will be on Duchenne Muscle Dystrophy (DMD), its physiotherapy management

  • Essay On Skeletal Muscle

    1078 Words  | 5 Pages

    Skeletal- Skeletal muscle is a muscle that is usually attached to bone, and is connected by collagen fibers. These fibers are known as tendons. Skeletal muscle is refers to many bundles of cells known as muscle fibers(fascicles). This type of muscle is highly composed of actin and myosin filaments. These filaments are repeated, forming sarcomeres. The sarcomeres are important to the skeletal muscle because they are responsible for the striations that appear on the skeletal muscle. It also forms the

    The structure of intertebral disc is complex. Nucleus pulposus has a well organized matrix which is laid down by relatively few cells. Nucleus pulposus is a gelatinous structure present in the centre and is contained in the periphery by annulus which is collagenous and cartilaginous, and two cartilaginous endplates cephalad and caudad. Collagen fibers from annulus continue and attach to the surrounding tissues, tying into the vertebral body along its rim, cartilaginous endplates superiorly and

    functions. After Latham’s significant works, Shapiro [2] and Fung and Yih [3] have described biologically and medically important reflux phenomenon. Vesicoureteral Reflux (VUR) is the backward flow of urine from the bladder into the kidneys. The muscles of the bladder and ureter along with the pressure of urine in the bladder prevent urine from flowing backward through the ureter. Due to this reason, urine generally flows from the kidneys to the bladder. VUR allows bacteria, which may be present

Tendons act to serve a connective tissue linking muscle to bony attachment points and in the case of the intermediate tendons that will act to link a muscle belly to another (Benjamin and Kaiser, et al). Tendons are a uniaxial and assist in force transmission thus being able to withstand external forces from multiple planes and angles (Kannus, 2008). Tendons

  • Bone Morphology Essay

    INTRODUCTION Bone is a living, complex, hard tissue that constitutes the vertebral skeleton. It is a composite comprising of well-defined structures at different scales of hierarchy. It has an organic matrix phase composed primarily of collagen, with the inorganic phase embedded in it. The calcium and phosphate containing inorganic crystals ultimately form hydroxyapatite. The bone morphology can be describes as comprising of the cortical bone - the outer compact region, and the trabecular bone -
