Exam 10: Muscle Tissue

Each thin filament consists of

In rigor mortis

A patient takes a medication that blocks ACh receptors of skeletal muscle fibers. What is this drug's effect on skeletal muscle contraction?

You try to pick up an object and discover that it is much heavier than you expected. Which process mustoccur in the muscle to increase tension so you can pick up the object?

Figure 10-2 Muscle Contractions Use Figure 10-2 to answer the following questions: -To produce a contraction similar to the one in graph (b), the muscle

The rapid rise and fall in force produced by a muscle fiber after a single action potential is a(n)

Many visceral smooth muscle cells lack motor neuron innervation. How are their contractions coordinated andcontrolled?

The region of the sarcomere that always contains thin filaments is the

Heat energy gained from muscle contraction is released by the ________ system.

Figure 10-1 Skeletal Muscle Fiber Use Figure 10-1 to answer the following questions: -Identify the structure labeled "1."

In the myofibril the thin filament is organized around a rod-like core protein called

The type of contraction in which the muscle fibers do not shorten is called

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

The region of sarcomere where thin and thick filaments are located is called the

The cytoplasm of the neuromuscular terminal contains vesicles filled with molecules of the neurotransmitter

When a muscle is stimulated repeatedly at a high rate, the amount of tension gradually increases to a steady maximum tension. This state of maximum tension is called

Thin filaments are mostly made of the protein

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

The type of contraction where the tension is less than the load is called

Stem cells located between the endomysium and sarcolemma that function in the repair of damaged muscle tissue are called
