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.
There are three types of motor nerves. Somatic motor nerves control skeletal muscles, which cause movement. Special visceral motor nerves control muscles in the face and neck. General visceral motor nerves control the smooth muscles that lack voluntary control, such as the heart. Another term for a motor nerve is motor neuron.. Motor nerves work by sending chemicals, known as neurotransmitters, across a gap between the nerve and the muscle. The neurotransmitters bind to receptors in the muscle fiber and trigger movement.
