Fig. 2-4 The blood and nerve supply of a synovial joint. An artery is shown supplying the epiphysis, joint capsule, and synovial membrane. The nerve contains (1) sensory (mostly pain) fibers from the capsule and synovial membrane, (2) autonomic (postganglionic sympathetic) fibers to blood vessels, (3) sensory (pain) fibers from the adventitia of blood vessels, and (4) proprioceptive fibers. Arrowheads indicate direction of conduction. Click for high resolution image.
