Which of the following structures or substances is incorrectly paired ...
Incorrect Pairing: Fibroblasts and Skeletal Muscle
The correct answer is option 'C', as it inaccurately associates fibroblasts with skeletal muscle. Below is a detailed explanation:
Understanding the Components
- Fibroblasts:
- These are specialized cells primarily found in connective tissues.
- Their main role is to produce collagen and other fibers, providing structural support to tissues.
- Skeletal Muscle:
- Skeletal muscle is a type of muscle tissue responsible for voluntary movements.
- It is composed of muscle fibers (myocytes) that are organized into bundles and are innervated by motor neurons.
Correct Associations
- Haversian System — Bone:
- The Haversian system, or osteon, is the fundamental functional unit of compact bone, providing strength and support.
- Platelets — Blood:
- Platelets, or thrombocytes, are small cell fragments in blood that play a crucial role in clotting.
- Chondroitin Sulfate — Cartilage:
- Chondroitin sulfate is a key component of cartilage, contributing to its elasticity and resistance to compression.
Conclusion
The pairing of fibroblasts with skeletal muscle is inaccurate, as fibroblasts are not involved in the structure or function of skeletal muscle. Instead, they are integral to connective tissues, while skeletal muscle is made up of muscle fibers. Understanding the distinct roles of these cells and tissues is essential for grasping the complexity of human anatomy and physiology.

Which of the following structures or substances is incorrectly paired ...
Fibroblasts are cells found in connective tissues, not skeletal muscle. They are responsible for producing collagen and other fibers. Skeletal muscle contains muscle fibers, not fibroblasts. The other pairings are correct: the Haversian system is part of bone, platelets are found in blood, and chondroitin sulfate is a component of cartilage.
