Which body systems are involved in a broken bone that requires pain signals to be sent along neural tissue?

• A. Skeletal, Nervous, Integumentary, and Circulatory
• B. Digestive, Immune, and Lymphatic
• C. Nervous, Muscular, and Endocrine
• D. Integumentary, Nervous, and Digestive

Answer: (A)

The process of a broken bone generating pain signals involves the skeletal, nervous, integumentary, and circulatory systems, making the first option the correct choice.

When a bone fractures, the skeletal system is directly affected as it is the structure sustaining the injury. The nervous system plays a crucial role in this scenario by transmitting pain signals from the site of the injury to the brain, allowing for the sensation of pain to be experienced. Additionally, the integumentary system could come into play if the break causes a breach in the skin, where pain receptors are also present. The circulatory system is involved as well since blood vessels may be damaged during the fracture, leading to inflammation and the release of substances that enhance the perception of pain.

In this context, the other options fail to encompass all the relevant systems. While some combinations may include the nervous system, they do not adequately cover the skeletal aspects and other components crucial to the pain response following a broken bone.
