Most immediate physiological adjustments to exercise occur prior to any change in tissue metabolic demand for oxygen or nutrients. This occurs because exercise increases sympathetic nervous system activity. With your knowledge of exercise and the control of alpha motor neurons by the primary motor cortex of the brain, how does increased exercise influence the sympathetic nervous system?
Which of the following choices best summarizes excitation-contraction coupling? A series of events in which an action potential triggers the release of chemical messengers A series of events in which actin binds myosin to enact contraction A series of events in which an electrical stimulus is conveyed to a muscle fiber to enact contraction A series of events in which calcium gradients are used to convey a signal to the muscle fiber to enact contraction
A research scientist is developing a new drug that blocks muscle cellreceptors that, when activated, stimulate a muscle contraction. In her firstexperiment, she used 250 mg of the new drug but saw no effect. In hersecond experiment, she increased the dosage to 750 mg. This dosagewas successful in blocking the muscle stimulation. Explain why increasingthe dosage would affect the outcome of the experiment.

The motor unit firing patterns are measured in a human hand muscle using an electromyography (EMG) recording. Which one of the following statements is the best description of the EMG pattern observed as the individual voluntarily attempts to make a low-level force of contraction in the muscle and steadily increases the force of contraction? Low amplitude spikes visible on the EMG trace at low force. Larger amplitude spikes become visible with increasing force of contraction. Low frequency of small amplitude spikes on the EMG trace at low force. Spike frequency and amplitude increase with increasing force. A large single deflection in the trace as the individual contracts the muscle. The deflection gets larger with increasing force. Low frequency of spikes on the EMG trace at low force. The frequency of spikes becomes more frequent with increasing force.
