The choices for this question are:
<span>(1) Medial rotation of an extended knee
(2) Lateral rotation of an extended knee
(3) Forward sliding of the tibia on the femur
(4) Forward sliding of the femur
The correct answer is "forward sliding of the tibia on the femur". This is in all due respect to the anatomy of the anterior cruciate ligament wherein it is attached to (1) the anterior intercondylar notch of the femur and (2) anterior intercondylar eminence of the tibia. If this ligament if torn, the tibia will be pushed more anteriorly than normal in relation to the femur, leading to pain and difficulty ambulating.</span>
Lets see this with example
if you put a red blood cell in a glass of water the red blood cell is in hypotonic solution and that water flows into less concentrated area ( in to the red blood cell ) which eventually will swell and burst.
Another plot is when we put the same red blood cell in a glass full of salty solution which is Heterogeneous solution. In these case the water will move out from the cell to the solution which cause the cell to shrink.
