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.

However, patients are more likely to describe fatigue with a more generalized medical condition, such as worsening congestive heart failure. When dealing with consultants, specific nomenclature will demonstrate an emergency medicine practitioners competency in evaluating weakness.
