 | Stronger "Muscle Contraction" i had to do a project in my bio class about muscle contraction so i decided to do somthing a little different from the norm. i described the whole process of how a muscle contracts in a rap by Kanye West's "Stronger". lyrics: n- n- now th- that will move me muscle contractions make me stronger nervous system needs to hurry up now Cause muscles cant wait much longer I know they need to move right now Cause I cant get much wronger body is waitin till its the right time now that's where ill get started the muscle contraction the muscle contraction lets see how it starts all right? fuel by motor neuron were contraction starts stimulus leading is action potential and this makes a synapse with the muscle fiber the synaptic terminal release Ach diffuse through cleft and bind to fiber membrane it triggers, an action potential action potential moves down T tubules SR releases calcium ions Troponin is where calcium will then bind It changes the shape of troponin removes blocking action of tropomyosin the myosin-binding sites are now exposed this is how process goes down so far theres alot that makes up all this don't think we are through yet, so much more, explainin n- n- now th- that will move me muscle contractions make me stronger nervous system needs to hurry up now Cause muscles cant wait much longer I know they need to move right now Cause I cant get much wronger body is waitin till its the right time now that's where ill get started the muscle contraction the muscle contraction go again back to where we were then I will start so myosin is now exposed myosin cross-bridges alternate back and forth attachin and detachin to actin actin filaments move toward sarcomere sliding of filaments by ATP by active transport calcium removed Goes to SR with end of action potential Then block of myosin-binding site The contraction ends which is real tight Muscle fiber rests which is most liked With stimulus present again which is all right process starts over, contractions on sight that's how contractions go down, we tight? Ugh, muscle contraction makin it (harder, faster, stronger) n- n- now th- that will move me muscle contractions make me stronger nervous system needs to hurry up now Cause muscles cant wait much longer I know they need to move right now Cause I cant get much wronger body is waitin till its the right time now that's where ill get started the muscle contraction the muscle contraction now you know how it goes, don't ya? Muscle contraction is just another process Now explained no questions needed Don't act like I never told ya (5x) Muscle contraction makin it (harder, better, faster, stronger) n- n- now th- that will move me muscle contractions make me stronger nervous system needs to hurry up now Cause muscles cant wait much longer I know they need to move right now Cause I cant get much wronger body is waitin till its the right time now that's where ill get started the muscle contraction (4x) now you know how it goes, don't ya? Muscle contraction is just another process Now explained no questions needed Don't act like I never told ya now you know how it goes, don't ya? Muscle contraction is just another process Now explained no questions needed Don't act like I never told ya Never told ya (4x) Never over (8x) well i hope you guys enjoy and learn a little somthin about muscle contraction. |

 | Muscle Motor Biosynthetics Beef Rib Eye Beef Steak animated with 40 VDC. This meat was packaged on September 9, 2007 and animated on September 13, 2007 after purchasing it from a grocery store. The goal with theyshallwalk. is to develop a powered exosuit LIFESUIT that is constructed of nanotech biosynthetic muscle fibers that will fit under a paralyzed persons clothes allowing them to walk. |

 | How the Body Works : Muscle Architecture Muscle Architecture Muscle architecture or the shape of skeletal muscles helps to shape their external appearance and determines their range of movement. Spiral muscles, as found in the trapezius muscle of the back, produce a twisting action at joints, Triangular bundles of muscle fibers, which appear fan-shaped, are arranged at an angle to the line of pull, as for example the temporalis muscles involved in chewing. Strap-like muscles, such as the sartorius of the leg and the sternohyoid of the neck, have parallel arrangement of fiber bundles. They are capable of both subtle and powerful contractions. Multipennate muscles, like the deltoid of the arm, are composed of many short bundles of fibers. Despite a limited range of shortening, these muscles are powerful in their actions. |

 | THE 2007 FELT DA You are looking at the fastest UCI legal Tri / TT bike built today. Developed over two years, with careful use of NACA aerofoil profiles, CFD flow modeling and wind tunnel experimentation, the DA frame system delivers unsurpassed aerodynamic advantage with incredible drive-train and steering stiffness. The DA features our revolutionary Bayonet Steering System which moves the steerer outside of the frame, improving steering stiffness 60% over a regular fork, while significantly reducing the aerodynamic drag on the bike. The aerodynamic advantage does not stop with the obvious innovations of the frame: The Bayonet Steering System integrates an adjustable stem, which with refined frame geometry and the new Felt 3.1 carbon fiber multi-position seat post, allows a comfortable, laid-down, flat back riding position. Such a riding position can help you drop seconds on your personal best by enlisting less fasttwitch muscle fibers, and allowing smoother airflow across your torso. |
 | Muscular System, Neuromuscular Junction Muscular System, Skeletal Muscle The junction between the terminal of a motor neuron and a muscle fiber is called the neuromuscular junction. It is simply one kind of synapse. (The neuromuscular junction is also called the myoneural junction.) |
 | COMPLEX TRAINING QUICKIE- do this for 10 rounds Complex training, one of the most advanced forms of sports training, integrates strength training, plyometrics, and sport-specific movement. It consists of an intense strength exercise followed by a plyometric exercise. Complex training activates and works the nervous system and fast twitch muscle fibers simultaneously. The strength exercise activates the fast twitch muscle fibers (responsible for explosive power). The plyometric movement stresses those muscle fibers that have been activated by the strength training movement. During this activated state, the muscles have a tremendous ability to adapt. This form of intense training can teach slow twitch muscle fibers to perform like fast twitch fibers.
