The core terms that recur across research, clinic, and movement — briefly explained.
- Collagen Anatomy
- The most abundant protein in connective tissue — roughly 30% of the body's total protein — and fascia's primary building block.
- Elastin Anatomy
- The rubber-like protein that lets connective tissue return to its original shape after being stretched.
- Fascia Anatomy
- The continuous fibrous connective-tissue network that wraps, separates, and connects every muscle, organ, nerve, and vessel.
- Fuzz Anatomy
- Gil Hedley's popular name for the loose fibres between muscle and fascia that thicken in stillness.
- Ground substance Anatomy
- The gel-like matrix between fibres that governs how easily fluid, nutrients, and signals move through connective tissue.
- Myofascia Anatomy
- Muscle and its surrounding fascia treated as a single functional unit of force transmission.
- Plantar fascia Anatomy
- The thick fascial sheet under the foot that stores and releases elastic energy with every stride.
- Thoracolumbar fascia Anatomy
- The large fascial sheet of the lower back — innervated like the cornea and often implicated in lumbar pain.
