Describe the following terms Muscle Insertion Agonist Antagonist Synergist Abductor
Regarding lines of pull, which of the following is not considered: A muscles relative length and ability to generate force The plane of motion through which a joint is capable of moving Relative relaxation or contraction of surrounding muscles All the above are considered None of the above are considered
We move a lot and do not even realize how intricate these movements may be from gross motor to fine motor manipulations. Briefly explain the steps involved in a single muscle contraction beginning at the neuromuscular junction through one complete contraction and relaxation for the sliding filament theory. Don’t forget to include all the major proteins (actin, myosin, troponin and tropomyosin) involved as well as calcium and ATP.
Which among the four choices below is NOT a typically way to measure muscle strength? Maximum force that can be exerted during an isometric contraction Maximum load that can be lifted at once Peak torque during an isokinetic contraction Number of repetitions before muscle fatigue sets in
Indicate if the statements are TRUE or FALSE. Statements TRUE FALSE To initiate muscle contraction, calcium ions bind to, and change the shape of the troponin protein molecules which then pull the tropomyosin proteins off the myosin binding sites of the actin helix. An accumulation of lactic acid is the principal cause of sore muscles. During rest, excess oxygen molecules in the sarcoplasm are attracted to a large protein molecule called myoglobin. Anaerobic respiration is the first choice of the muscle cell for the production of ATP.
During a Physical Education class, you ask your students to perform a standing vertical jump. Identify the type of muscle contraction involved in the jump and describe the movement patterns of the concentric and eccentric phases. Outline the agonists, antagonists and synergist muscles, which contribute to maximum jump height. Identify the major lower body joints and joint movements, which contribute to the concentric phase of the jump.

The sliding filament theory is used to explain the physiology of skeletal muscle contraction. On your own, using what you have learned from this activity, write your own description of what the sliding filament theory states.
Fast oxidative glycolytic fibers in skeletal muscle are used Select one: O a. intermittently, for activities requiring more force output than the fast glycolytic fibers alone can produce. O b. constantly, for postural activities such as standing and sitting. O c. intermittently, for activities requiring more force output than the slow oxidative fibers alone can produce. O d. only for motions requiring maximum power output, such as jumping.
Indicate which of the following are true. Chronically shortened muscles will lose sarcomeres in series in order to maintain ideal amounts of myofilament overlap. Contractile force is proportional to the length of a muscle. Muscle organ contraction is all or nothing. Muscle cells are surrounded by an endomysium. Actin is the thick filament and Z-lines are where the cross-bridges zig-zag to adjacent actin filaments. Muscles with fewer motor units are weaker, i.e., capable of less force. A nerve impulse, calcium, and ATP are necessary for muscle contraction. Tendons attach bones to bones and help to limit the range of motion at joints. Muscle tissue is very dynamic and will respond to chronic stress by becoming stronger (making more myofilaments), chronic contraction by becoming shorter (losing sarcomeres in series), and stretching by becoming longer (adding sarcomeres in series). Myofilaments are actually long strands of proteins.
Muscles in unfused/incomplete tetanus reach maximum tension while relaxing slightly between stimuli. True False
The following is a list of conditions that are associated with the muscular system. Take some time and write notes about each of the conditions. You may make the notes taken from text books or other resources, or you may make the notes as a result of people you have cared for. If you are making notes about people you have cared for you must ensure that you adhere to the rules of confidentiality. 1. tetanus 2. rigor mortis 3. muscle cramps
For stroke patients or others requiring physical therapy, resistance exercise can be very beneficial. One such exercise device attaches to the arm and hand and provides resistance to wrist movement over a normal range of movement (extension and flexion). Before designing the device, you need to determine its specifications (i.e., characteristics, functions, physical requirements, etc.). determine the requirements for the wrist exercise device:
