The process by which greater force is generated by muscle is called…
a. Transverse tubules
b. Sarcomere cycling
c. Motor unit recruitment
d. Cross bridge cycling
e. Troponin-tropomyosin complexing
Homework Answers
c.) Motor unit recruitment.
Motor unit recruitment is a process by which different motor units are activated to produce a type of muscle contraction, in this more motor units are activated, which will result in more muscle fiber being activated and therfore a stronger muscel contraction occurs, if only a single motor neuron is activated than it will result in weak contraction, so higher the recruitment highe will be contraction.
While cross bridge cycline is mechanism of muscle contraction in which myosin and actin form a cross bridge for a muscle contraction tpo occur
Troponin-tropomyoscin complex allows the myosin and actin to interact so that a cross bridge can form
Transverse tubules is an extension of cell membrane that penetrate into the center of skeletal and cardiac muscle

Question 28 4 pts Once the action potential occurs in the sarcolemma, it spreads moving down the T-tubules. What next? What is the correct order of events which result in skeletal muscle contraction? (4 points) a. Once the muscle cell action potential is initiated then calcium ions are released from the sarcoplasmic reticulum. These calcium ions bind to troponin. With this binding, tropomyosin is pulled away from the active sites on actin. Myosin can bind with actin forming a cross...

1) You are investigating the force generated by the sarcomeres in a myofibril of a muscle. Let's assume you have a way of quantifying the number of actin-myosin cross bridges. You notice that for all of your sarcomeres, increasing the number of actin-myosin crossbridges does not increase the force generated by the sarcomere. What is going on? A) The sarcomeres are too contracted, hence sarcomere length is a limiting factor for force generated rather than the number of cross-bridges...

Which of the following events does not occur during the depolarization phase of a skeletal muscle action potential? A. T-tubules depolarize B. troponin changes shape, moving tropomyosin off of actin's myosin binding sites C. Ca++ is released from the sarcoplasmic reticulum D. Ca++ channels in the axon terminal open

1. True -False. If a statement is True, place a T to the left of it. If a statement is False, place an F to the left of it. Thin filaments in smooth muscles attach to Z discs. The majority of ventricular filling occurs during the period of atrial contraction known as the period of rapid filling. Closure of the atrioventricular valves occurs at the end of diastole/beginning of systole. Tetanus in skeletal muscles is the result of increasing the...

1.The hyperbolic force dependence of muscle shortening velocity results from the fact that: a. Muscle contraction is best described by a Hookean Spring model. b. Energy is dissipated by mechanical work and viscous drag, both of which depend on changes in sarcomere length. c. ATPase cycling is hyperbolically dependent on the local concentration of Actin. d. Ftot = funi*D*N e. Heat liberation by muscle is constant.
