This is a synergist of the Quadriceps femoris Select one: O a. Adductor of the thigh O b. Hamstring O c. Gluteus maximus
Which of the following is NOT true about the mechanism of muscle contraction? Select one: O a. Action potential crosses the synaptic gap to the motor end plate O b. Action potential in the muscle cell activates the calcium channels to open O c. Calcium rushes down the concentration gradient into the sarcoplasm O d. Nicotinic receptors when activated start the action potential in the muscle cell
The following is true about cross-bridge formation between actin and myosin: Select one: O a. It happens only in the presence of calcium ions O b. It allows myosin to move using actin as the pulling rope O c. It causes the sarcomeres to stretch O d. It causes the Z-lines to move away from each other
