GTS Fascial System & Connective Tissue Anatomy 2 — Questions and Answers
Question 1: What is the primary role of hyaluronic acid within the fascial system?
- Providing tensile strength to collagen fibers
- Lubricating fascial layers to allow gliding (Correct answer)
- Stimulating nerve regeneration
- Producing inflammatory cytokines
Correct answer: Lubricating fascial layers to allow gliding
Hyaluronic acid is a glycosaminoglycan in the loose connective tissue between fascial layers that acts as a lubricant, facilitating the sliding and gliding of adjacent fascial planes.
Question 2: Which type of fascia is the most relevant target when applying Graston Technique to deep musculature?
- Superficial fascia
- Deep fascia (Correct answer)
- Visceral fascia
- Meningeal fascia
Correct answer: Deep fascia
Deep fascia is the dense, organized connective tissue that directly invests muscles and tendons, making it the primary target when using IASTM tools to address musculoskeletal restrictions.
Question 3: What structural change to collagen occurs during pathological scar tissue formation?
- Collagen becomes more elastic and flexible
- Collagen fibers become randomly oriented instead of parallel (Correct answer)
- Collagen production decreases significantly
- Type II collagen replaces Type I collagen
Correct answer: Collagen fibers become randomly oriented instead of parallel
During scar tissue formation, collagen fibers are deposited in a disorganized, random pattern rather than the parallel alignment of healthy tissue, resulting in reduced functional capacity.
Question 4: Which mechanical property allows fascia to resist deformation yet return to its original shape after loading?
- Plasticity
- Viscosity
- Viscoelasticity (Correct answer)
- Rigidity
Correct answer: Viscoelasticity
Viscoelasticity combines elastic behavior (deformation resistance and recovery) with viscous behavior (time-dependent response), allowing fascia to absorb forces and return to its original shape.
Question 5: Which mechanoreceptors in superficial connective tissue are sensitive to light touch and low-frequency vibration?
- Meissner's corpuscles (Correct answer)
- Pacinian corpuscles
- Ruffini endings
- Golgi tendon organs
Correct answer: Meissner's corpuscles
Meissner's corpuscles are encapsulated mechanoreceptors located in the superficial connective tissue that are specifically tuned to detect light touch and low-frequency vibration.
Question 6: Which phase of tissue healing is characterized by fibroblast proliferation and new collagen synthesis?
- Hemostatic phase
- Proliferative phase (Correct answer)
- Remodeling phase
- Inflammatory phase
Correct answer: Proliferative phase
The proliferative phase (approximately days 4–21) is defined by fibroblast proliferation and Type III collagen synthesis, beginning the structural rebuilding of damaged tissue.
Question 7: Which structural property primarily distinguishes tendons from ligaments in terms of their connective tissue organization?
- Tendons contain Type II collagen; ligaments contain Type I collagen
- Tendons connect muscle to bone; ligaments connect bone to bone (Correct answer)
- Tendons are composed of loose connective tissue; ligaments are dense
- Tendons are highly vascular; ligaments are avascular
Correct answer: Tendons connect muscle to bone; ligaments connect bone to bone
The defining structural distinction is their anatomical role: tendons transmit muscle force to bone (muscle-to-bone), while ligaments stabilize joints by connecting bone to bone.
