Cocaine effects on body

(Complete Item Description)

Abstract:: Imagine that the circles, called vesicles, at the top of the images are filled with molecules of dopamine, such as the arrow labeled as "1". The vesicles fuse with the axonal membrane to release the dopamine into the area called the synaptic gap. Dopamine can then activate the next axon ("6") or be recycled into the previous axon (through "5"). Cocaine blocks the channel that takes dopamine up again ("5"), so dopamine activates the next axon continuously. This can cause extreme mood swings.
