g is also affected by the fact that the Earth rotates and an observer on its surface therefore experiences a centrifugal force. We can summarise by saying: (1) If the Earth were a non-rotating perfect sphere, the acceleration due to gravity would be constant. (2) Because of rotation, the Earth is flattened at poles. This affects g in two ways:-
Multifocal motor neuropathy (MMN) is a disease that affects your body's motor nerves. Those are the nerves that control your muscles.
This type of peripheral nerve disease is inherited. Genetic errors may cause any number of disturbances of the peripheral nerves mainly by damaging the myelin sheath or the axons that make up the nerve fibers. These types of neuropathy can be classified as : Hereditary motor and sensory neuropathies (HMSNs)
