Nerves form a network of pathways for conducting information throughout the body. Any of the cordlike bundles of fibers made up of neurons through which sensory stimuli and motor impulses pass between the brain or other parts of the central nervous system and the eyes, glands, muscles, and other parts of the body. Having passed the medial (upper) canal of arterial and venous lacuna of the tarsal tunnel, the nerve lies behind the vessels situated above the abductor muscle of the first toe. Difficult test to perform, therefore: May need to perform side-to-side comparisons (comparing amplitude and peak latency) CPT codes for nerve conduction studies. The medial plantar nerve arises under the flexor retinaculum, runs deep to the AbH, and, with the medial plantar vessels, travels between the AbH and flexor digitorum brevis . The EMG also showed that the motor function of those nerves weren't working, but the sensory aspect was fine. A nerve provides a common pathway for the electrochemical nerve impulses called action potentials that are transmitted along each of the axons to peripheral organs or, in the case of sensory .
