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.
Symptomatic dysfunction of the bulbar musculature is an important feature of NMJ processes and will manifest as dysphonia, dysphagia, dysarthria, and difficulty handling secretions. Impulses flow from the cerebrum out to the muscle, with stepwise compartmentalization of the anatomical subunits in between.
