The Water Cycle: The U.S. Geological Survey explains what the water cycle is and where water comes from. Animated Water Cycle: This animated water cycle diagram allows kids to click on different parts of the cycle to see how water changes form and moves.
The neuromuscular junction (NMJ) is the site of communication between motor nerve axons and muscle fibres. It is composed of four specialised cell types: motor neurons, Schwann cells, muscle fibres and the recently discovered kranocytes.
Learning objectives: Disorders affecting the neuromuscular junction (NMJ) are among the most interesting. and rewarding seen in the EMG laboratory. These disorders are generally pure motor. syndromes that usually preferentially affect proximal, bulbar, or extraocular muscles. They are confused occasionally with myopathies.
