Exam 9: Muscles and Muscle Tissue

Which muscle cells have the greatest ability to regenerate?

Figure 9.1 Using Figure 9.1, match the following: -Connective tissue covering the exterior of a muscle organ.

When a muscle is unable to respond to stimuli temporarily,it is in which of the following periods?

Describe how the unique contractile mechanism of smooth muscle allows it to contract and remain in a contracted state for long periods of time with relatively little energy expenditure.

Muscle contraction will always promote movement of body parts regardless of how they are attached.

An increase in the calcium ion level in the sarcoplasm starts the sliding of the thin filaments.When the level of calcium ions declines,sliding stops.

Which of the following would be recruited later in muscle stimulation when contractile strength increases?

Match the following: -The stimulus above which no stronger contraction can be elicited,because all motor units are firing in the muscle.

What is the primary function of wave summation?

Figure 9.1 Using Figure 9.1, match the following: -Bundle of muscle cells surrounded by a perimysium.

Muscle tone is ________.

Approximately 80% of a muscle fiber's volume are the myofibrils.This characteristic reflects muscles ability to ________.

A smooth,sustained contraction from rapid stimulation is called ________.

A patient is admitted for electroconvulsive treatment (ECT).The physician orders the neuromuscular blocking agent succinylcholine to reduce trauma by relaxing skeletal muscles.Explain the process of muscle contraction and how a neuromuscular blocking agent such as succinylcholine would interfere with muscle contraction.

Although all the anatomical parts of muscle work together to give it it's characteristics,which of the following proteins listed below would be most associated with the characteristics of contractility?

Match the following: -Used to convert ADP to ATP by transfer of a high-energy phosphate group.A reserve high-energy compound.

When a geriatric patient is admitted to the postsurgical unit,an important nursing measure is to prevent the loss of muscle mass.What is the term used for loss of muscle mass and how can the patient prevent it?

Which of the following is the correct sequence of events for muscle contractions?

What part of the sarcolemma contains acetylcholine receptors?

Creatine phosphate functions in the muscle cell by ________.
