Mononeuropathy: A disorder of a single nerve or nerve trunk. Mononeuropathies may be due to entrapment, compression, stretch injury, ischemia, infection, or inflammation of a nerve. The most common entrapments are of the median nerve of the wrist (the carpal tunnel syndrome) and ulnar nerve of the elbow (the cubital tunnel syndrome). In the lower extremities, common nerve entrapments are of the peroneal nerve (peroneal neuropathy) and the lateral femoral cutaneous nerve (meralgia paresthetica).
Polyneuropathies are generalised disorders of the peripheral nervous system. They affect individually or in combination the motor, sensory and vegetative nerves, the sheath-like structures of their connective tissue and the blood vessels, which supply them. Motor nerve fibres conduct instructions to the muscles. Sensory nerve fibres conduct sensations from the skin, neuromuscular spindles, tendons and joints to the spinal cord. Vegetative or autonomous nerve fibres innervate the internal organs, the blood vessels and the sweat glands in the skin.
