Answer to Question 1

Ca++ entry into terminal causes release of neurotransmitter (NT) molecules, primarily from vesicles, into cleft. NT passively diffuses across cleft and binds to post-synaptic receptors to induce either IPSP or EPSP, depending upon the type of ion flow into or out of post-synaptic neuron. The NT then dissociates from the receptors and may undergo reuptake back into the axon terminal or nearby glial cells, be enzymatically inactivated, or diffuse throughout the extracellular fluid.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
