2/14/2012 Anatomy and Physiology Muscle Grip Strength Lab Report Introduction: Skeletal muscle is a form of striated muscle tissue existing under the voluntary control of the somatic nervous system (Medscape 1). Skeletal muscle is part of the three big muscle types‚ it is connected to bones by tendons (Medscape 1). Muscle grip strength is significant to an individual because it helps the person know the ability of muscle power and force that they have in their

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 failure

1) How are osteoarthritis and rheumatoid arthritis different? Osteoarthritis usually affects people 60 or older and is caused by increasing wear and tear at the joint surfaces or from genetic factors affecting collagen formation. On the other hand rheumatoid arthritis is an inflammatory condition. It is caused by the body attacking its own tissues as well as allergies‚ bacteria‚ viruses‚ and other genetic factors. 2) When the triceps brachii muscle contracts‚ what movements does it produce? When

Advantages and Disadvantages of Robot Technology Many type of robots that have been created and developed by the engineers to help human managing and assisting human in daily tasks. Robots are simply machines that have the ability to perform specific tasks and typically controlled by a computer or collection of computers. The robot can only perform those tasks for which they have been programmed. Main advantage of the robot technology is the increasing in productivity‚ safety‚ efficiency

Date: Conducted by: Brenan‚ Jay and Satoro AIMS: * Demonstrate how vibration induces illusions of movement * To determine whether vibration has had any effect on ability to match joint angle between left and right arms * Observe the effect of fatigue on ability to sense force. INTRODUCTION Proprioception is defined as the sense of the relative position of neighboring parts of the body. It is the ability to distinguish how ones body is situated‚ either in motion or stationary

Musculoskeletal: The human musculoskeletal system or the locomotor system is made from cartilage‚ bones‚ ligaments‚ tendons and muscles. This system give humans the ability to move using their muscular and skeletal systems. The musculoskeletal system is being controlled by the nervous system to provide voluntary movements. The skeletal system and the muscle system maintain to posture and produce heat for the body. Increased blood supply: As people start to exercise the muscles will start wanting

Abstract The purpose of this experiment was to use the muscle tension and the electrical activity in the dominant and non-dominant forearm muscle‚ the flexor digitorum superficialis‚ to analyze the determinants of muscle tension and fatigue‚ and the reasons as to why differences may occur between the dominant and non-dominant arm. The generation of tension in a muscle is determined by the major type of motor unit being recruited‚ as well as the rate in which action potentials are being fired. A subject

Stimulus-Dependent Lab A motor unit is a motor neuron and the muscle fiber it controls. A whole muscle is made up of hundreds of motor units that are handled by different motor neurons that react at different levels of stimulation. The electric shock acts as an action potential by changing the membrane permeability allowing the sodium and potassium ions to pass through. At different levels of stimulation the motor neurons stimulate a motor unit and the more stimulation the more motor units become
