Exam 10: Muscle Tissue

Large-diameter,densely packed myofibrils,large glycogen reserves,and few mitochondria are characteristics of

Since each myofibril is attached at either end of the muscle fiber,when sarcomeres shorten,the muscle fiber

During the recovery period following exercise,all of the following are true except

Figure 10-2 Muscle Contractions Use Figure 10-2 to answer the following questions: -Why is there partial relaxation in graph (c)?

A resting muscle generates most of its ATP by

Nerves and blood vessels that service a muscle fiber are located in the connective tissues of its

When a skeletal muscle fiber contracts,the

Which of the following would not lead to increased oxygen consumption?

After heavy exercise,if energy reserves in a muscle are depleted,________ occurs.

When calcium ion binds to troponin,

Which of the following acts as an ATPase during the contraction cycle of muscle?

After death,muscle fibers run out of ATP and calcium begins to leak from the sarcoplasmic reticulum into the sarcoplasm.This results in a condition known as

Put the following structures in order from superficial to deep. 1) muscle fiber 2) perimysium 3) myofibril 4) fascicle 5) endomysium 6) epimysium

Communication between axons and muscle fibers occurs at specialized synapses called

Figure 10-1 Skeletal Muscle Fiber Use Figure 10-1 to answer the following questions: -Which structure has pumps to remove calcium ions from the sarcoplasm to produce relaxation?

Muscle fibers differ from "typical cells" in that muscle fibers

Physical evidence that supports the sliding filament theory of muscle contraction includes

Muscles that move the eyeball have ________ fibers.

A weight-lifter strains to lift a heavy weight and there is no movement of the person's arms holding on to the weight.This type of contraction is called a(n)________ contraction.

The protein that is found in the Z line of a sarcomere is called
