Correction:Pathophysiology and etiology of nerve injury following peripheral nerve blockade

Under the discussion section, in the anatomical considerations paragraph the article reads: A nerve can be considered a distinct organ composed of neural tissue, a connective tissue stroma, and blood supply.Nerve cells, or neurons, are composed of a cell body, dendrites, and an axon.The axon is a cytoplasmic extension of the neuron that transmits electrical signals along its length from the cell body proximally to any distance from a few millimeters to nearly 1 m distally.Most peripheral nerves transmit both afferent motor and efferent sensory signals.In the peripheral nervous system, the majority of axons have a sheath of Schwann cells that encase the axon in a layer of myelin (figure 1).There is an error in the penultimate sentence which should read: Most peripheral nerves transmit both efferent motor and afferent sensory signals.
