Question

question 10 (mandatory) (2.5 points) match the following definitions with their correct term. 1. the part of the muscle that is enclosed in perimysium. 2. when the liver neutralizes lactate back into pyruvate and glucose. 3. the part of a muscle fiber that aids in restoring sarcomere length after a contraction and prevent extreme stretching. 4. the connection between myosin head and g - actin. 5. a motor neuron and all the muscle fibers that it controls. 6. lactic acid fermentation. 7. myofibril. 8. powerstroke.

Explanation:

These are standard muscle - related definitions. Fascicles are muscle fiber bundles surrounded by perimysium. Titin is a protein with elasticity functions. Cross - bridge formation is key in muscle contraction. A motor unit is a neuron - fiber functional unit. The Cori cycle involves lactate - glucose interconversion between muscle and liver. Lactic acid fermentation is related to lactate production. Myofibrils are muscle fiber components. Powerstroke is part of muscle contraction mechanics.

Answer:

1. fascicle - The part of the muscle that is enclosed in perimysium.
2. titin - That aids in restoring sarcomere length after a contraction and prevent extreme stretching.
3. cross - bridge formation - The connection between myosin head and G - actin.
4. motor unit - A motor neuron and all the muscle fibers that it controls.
5. Cori cycle - When the liver neutralizes lactate back into pyruvate and glucose.
6. lactic acid fermentation - Lactate back into pyruvate and glucose.
7. myofibril - The part of a muscle fiber.
8. powerstroke - Controls.
