Anatomy & Physiology Musculoskeletal #23

Question

Which student statement accurately reflects the relationship between cardiac muscle and skeletal muscle tissue?

Answers

  1. “Skeletal and cardiac muscles are both involuntary.”
    • Rationale:

      This is not a true statement regarding the relationship between skeletal and cardiac muscles as these muscles are not both involuntary; the cardiac muscles are involuntary.

  2. “Cardiac muscle is striated while skeletal muscle is smooth.”
    • Rationale:

      This is not a true statement regarding the relationship between skeletal and cardiac muscles. Both of these muscles are striated; striation is defined as lines or bands in the muscle.

  3. “Skeletal muscle is voluntary while cardiac muscle is involuntary.”
    • Rationale:

      This is a true statement regarding the relationship between skeletal and cardiac muscles. Skeletal muscle is under voluntary control while cardiac muscle is under involuntary control.

  4. “The cardiac muscles are connected to bones while skeletal muscles are found in the heart.”
    • Rationale:

      This is not a true statement regarding the relationship between skeletal and cardiac muscles. Skeletal muscles are connected to bones while cardiac muscle is found in the heart.

Overview

The musculoskeletal system is broken down into two subsystems, the muscular system and the skeletal system.

Explanation

Learning Outcomes

The muscular system can be described as having three different types of muscles. These muscles include cardiac, skeletal, and smooth muscles. An accurate statement regarding the relationship between skeletal and cardiac muscles is that skeletal muscle is voluntary while cardiac muscle is involuntary.

Test Taking Tip

Ask yourself if each statement is true or false. The true statement is the correct choice for this question.
