Muscle & bone ↗Tendons connect muscle to bone
Tendons transmit muscle force and can store and return elastic energy. Their contribution depends on task, loading rate, and tissue properties.

Transfer force.
Remodel slowly.
Tendons, ligaments, fascia, capsules, and extracellular matrix support movement and joint stability, but their mechanical properties and adaptation clocks differ from muscle fibers.
Ligaments guide motion
Ligaments help constrain and guide joint movement with capsule, bone shape, cartilage, muscle force, and sensory feedback.
Fascial planes distribute force
Fascial and other connective tissues provide pathways for force transfer and sliding among structures, while also containing nerves and vessels.
Stability is a system property
Joint stability arises from passive structures, active muscle control, sensory information, external load, and movement history.
Fibers provide tensile structure
Collagen-rich matrix is synthesized, organized, cross-linked, and degraded continuously; organization is as important as total material.
Resident cells sense and respond
Tenocytes, fibroblasts, immune cells, vascular cells, and neighboring tissues respond to mechanical, inflammatory, and metabolic context.
Healing changes over phases
Inflammation, matrix deposition, vascular changes, and remodeling overlap after injury; repaired tissue may not exactly reproduce original structure.
Matrix adaptation is not immediate
Connective-tissue turnover often unfolds across longer clocks than acute muscle metabolism, making abrupt load jumps a different stimulus.
Gradual loading supports adaptation
Appropriate progression balances stimulus with recovery, but suitable loading differs by tissue, task, age, injury history, health, and clinical advice.
Pain is important but nonspecific
Pain can reflect many interacting biological, mechanical, and nervous-system factors and cannot on its own identify tissue damage or readiness.
Some signs need assessment
A sudden pop, deformity, rapid swelling, instability, locking, loss of function, or inability to bear weight can require prompt evaluation.
This is not a rehabilitation plan
The map cannot diagnose a tendon or ligament condition, choose exercises, set loading progression, or determine safe return to sport or work.
