The Purpose of Crying

What happens when you cry, exactly? A salty fluid chock full of protein, water, mucus and oil is released from the lacrimal gland.This fluid, better known as tears

 In fact, three types of tears exist, all with different purposes. Basal tears are omnipresent in our eyes. These constant tears are what keep our eyes from drying out completely. the second type is reflex tears, which serve to protect the human eye from harsh irritants such as smoke, onions or even a very strong, dusty wind. To accomplish this feat, the sensory nerves in your cornea communicate this irritation to your brain stem, which in turn sends hormones to the glands in the eyelids. These hormones cause the eyes to produce tears, effectively ridding them of the irritating substance.

The third type of tears is emotional tears. It all starts in the cerebrum where sadness is registered. Theendocrine system is then triggered to release hormones to the ocular area, which then causes tears to form.

 Reflex tears are generally found to be about 98 percent water, whereas several chemicals are commonly present in emotional tears

 First is a protein called prolactin, which is also known to control breast milk production. Adrenocorticotropic hormones are also common and indicate high stress levels. The other chemical found in emotional tears is leucine-enkephalin, an endorphin that reduces pain and works to improve mood.

Frey estimates that women have about 60 percent more prolactin in their bodies at any given time than men [source: Women's Health]. He also believes that these elevated levels cause women to cry more because the protein revs up the endocrine system, which makes people more likely to cry.

Women tend to cry more loudly and with many more tears than men. This is believed to be because men have smaller tear glands than women, so they just can't produce the volume in one sitting that women do.

crying could be a safety mechanism of sorts because it rids the body of stress-related toxins. 

so y we cry while watchng Movie?

 The neuropeptide oxytocin  is a modulating empathy.

Oxytocin engages brain circuits that make us care about others, even complete strangers. 

Perhaps surprisingly, oxytocin engages at the smallest suggestion that someone wants to connect to us, for example, that a person's brain releases oxytocin when he or she is entrusted with money by a stranger. Now Could oxytocin make us cry in movies?

Yes. Acc to research those who saw the highly emotional part of the videos had a 47% increase in oxytocin as measured in blood. Controlling for distress (which was associated with elevated stress hormones), empathy was highly correlated with the spike in oxytocin.So oxytocin is a physiologic signature for empathy.Also women release more oxytocin and were more empathic than men.

So, we cry at movies because the oxytocin in the human brain is imperfectly tuned. It does not differentiate between actual human beings and flickering images of human beings. Either one is enough to kick oxytocin into high gear and impel our empathy
