    Structure of Nerve
    • A nerve consists of a bundle of nerve fibres. This bundle is called fasciculi.
    • A nerve is surrounded by epineurium, a layer of connective tissue. 
    • A fasciculus is covered by perineurium which is connective tissue.
    • Inside the nerve, each nerve fibre is surrounded by endoneurium.
    • A nerve conveys information in the form of electrochemical impulses (known as nerve impulses or action potentials) carried by the individual neurons that make up the nerve.
    • These impulses are extremely fast, with some myelinated neurons conducting at speeds up to 120 m/s.
    • The impulses travel from one neuron to another by crossing a synapse, and the message is converted from electrical to chemical and then back to electrical.
