Medical Glossary - N

  • negligence
    An employer can be sued for compensation for industrial disease or injury but, for an action of negligence to succeed, it has to be proved that the job actually caused the disease, it could have been prevented by the assessment and monitoring of working conditions and that a good employer would thus have prevented it.

  • neuralgia
    An acute pain in a nerve or a series of nerves especially in the head or face.

  • neurasthenia
    An old-fashioned unspecific word usually meaning weakness of the nervous system or nervous exhaustion. Not a phrase that is used much these days.

  • neuritis
    Inflammation of a nerve. This may be localised to one point of the body - as in sciatica - or it may be more generally known as multiple neuritis or polyneuritis.

  • neuro muscular junction
    The specialised area where a motor nerve ends in close proximity to the muscle membrane and is able to initiate muscle contraction.

  • neurodynamic testing
    See Brachial Plexus and Adverse Neural Tension.

  • neurolernma
    A membranous sheath encasing a nerve.

  • neuropsychology

  • no fault system
    This is a compensation scheme such as has been set up in New Zealand and Sweden where an insurance company pays compensation following diagnosis of injury. It is not necessary to prove negligence. The schemes are said to be quick and cheap to administer but have the disadvantage of not adapting quickly to new industrial diseases or compensating where there is only a probability that the problem is work related.

  • nociceptors
    Nerve endings which detect and respond to painful or unpleasant stimuli.

  • nosology
    The branch of medical science dealing with the systematic classification of diseases usually described as the nomenclature of disease.
