Skeletal muscle moves because we want it to. It is controlled voluntarily (consciously). There is 2 types of contraction Isometric: As the muscle contracts‚ it remains the same length whilst the tension increases in an attempt to overcome the opposing force. Example: Holding a glass of water still in front of you. Isotonic: As the muscle contracts its length changes whilst the tension remains constant or develops to overcome the opposing force. Example: Lifting a glass of water to your mount and

The 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

face with scary image. From this I came with an idea for my game with few adaptions‚ in this case the adaptions are the red balls and the ‘replay a level’ screen. Technical research For technical research I used the school computers‚ internet and PowerPoint. Design Ideas Ideas that I considered were: * Core colour for all the slides * Ball to kill of players * How the game is structured * Time limit * Extra lives Final Design Ideas That design that I ended up with is:

Skeletal Muscle Physiology Activity 1 1. Skeletal muscle fiber- long‚ cylindrical cell with multiple oval nuclei arranged just beneath the sarcolemma Motor unit- all of the muscle cells controlled by a single motor neuron Skeletal muscle twitch- a single stimulus-contraction-relaxation cycle in a skeletal muscle Electrical stimulus- uses an electrical current to cause a single muscle or a group of muscles to contract Latent period- the time between the stimulation of a muscle and the start

ACTIVITY 6: The Skeletal Muscle Length-Tension Relationship 33. In a force-length graph‚ a. the muscle length is the independent variable. b. the amount of force generated is the dependent variable. c. both active and passive forces must be considered. d. All the above are correct. correct answer 34. According to your lab manual‚ the protein titin is the primary cause of _________ __________. Passive Force 35. In this lab simulation‚ the muscle length of _______

to start off the phone call. Susan is inquiring about some of the functions that PowerPoint has to offer. She has asked about how some of the features of PowerPoint can support her data that she has gathered. I will begin by repeating back her question to verify that we are on the same page. One of the challenges I will probably face is explaining the terms to the customer in a manner she would understand. PowerPoint is a user-friendly program. Sometimes explaining something easy is not easy at all

Lab 4: Skeletal Muscle Function Exercise 5: The Length-Tension Relationship Materials and Methods In this experiment I used a frog anesthetized with ms222. The frog’s skin is cut and removed from both the legs‚ the Achilles tendon is cut and the tendon and calf muscle are removed from the lower legs. The femur muscle is also cut. Attached to the legs are femur clamps which are connected to the transducer arm‚ stimulation electrodes are then positioned against the muscle. I plugged the output
