Chapter 9, Problem 1a

Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
A property of all muscle cells is elasticity, which means that the tissue is able to stretch.

Verified step by step guidance
1
Understand the key terms in the statement: 'elasticity' and 'stretch'. Elasticity refers to the ability of a muscle to return to its original shape after being stretched or compressed, while 'stretch' refers to the ability to lengthen or extend.
Analyze the statement: It claims that elasticity means the tissue is able to stretch. This is incorrect because elasticity specifically refers to the ability to return to the original shape, not the ability to stretch.
Correct the false statement: A property of all muscle cells is elasticity, which means that the tissue is able to return to its original shape after being stretched or compressed.
Review the properties of muscle tissue: Muscle cells have four main properties—excitability (responsiveness), contractility (ability to contract), extensibility (ability to stretch), and elasticity (ability to return to original shape).
Conclude by ensuring the corrected statement aligns with the definitions of these properties and the context of muscle tissue functionality.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Muscle Cell Properties

Muscle cells, or myocytes, possess unique properties that enable them to function effectively. These properties include contractility, excitability, extensibility, and elasticity. While elasticity allows muscle tissue to return to its original shape after being stretched, not all muscle cells exhibit this property to the same degree, particularly in the case of cardiac and smooth muscle compared to skeletal muscle.

Elasticity in Muscle Tissue

Elasticity refers to the ability of a material to return to its original shape after deformation. In muscle tissue, this property is crucial for maintaining functionality during movement. However, while elasticity is a characteristic of muscle tissue, it is not universally applicable to all types of muscle cells, as some may have limited elastic properties depending on their specific roles in the body.

True or False Statements

In evaluating statements as true or false, it is essential to understand the definitions and characteristics of the subject matter. A false statement can often be corrected by providing accurate information or clarifying misconceptions. In this context, recognizing the nuances of muscle cell properties is vital for determining the truthfulness of the statement regarding elasticity.
