Anatomy & Physiology Musculoskeletal #22

Question

Which is the location where cardiac muscle tissue is found in the human body?

Answers

  1. The legs
    • Rationale:

      The legs contain muscles which can be either superficial or deep skeletal muscle tissue. Cardiac muscle tissue is only found in the heart.

  2. The arms
    • Rationale:

      The arms contain muscles which can be either superficial or deep skeletal muscle tissue. Cardiac muscle tissue is only found in the heart.

  3. The lungs
    • Rationale:

      The lungs have no skeletal muscles. The work of breathing is done by the abdominal muscles, the diaphragm, the intercostal muscles, and the muscles in the neck. Cardiac muscle tissue is only found in the heart.

  4. The heart
    • Rationale:

      The only location where cardiac muscle is found is within the heart tissue.

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; they are cardiac, skeletal, and smooth. Cardiac muscle is a striated muscle. It is not under voluntary control and is found in the heart.

Test Taking Tip

Consider where each type of muscle is located to answer this question correctly.
