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.
ISTJ stands for Introversion, Sensing, Thinking and Judging, which are the ways in which you prefer to energize, perceive information, make decisions and live your life. The MBTI is based on Jung's personality theory.
