Crying
Crying is believed to be an outlet or a result of a burst of intense emotional sensations, such as agony, surprise, or joy and could explain why people cry during cheerful events, as well as very painful events. A globus sensation experienced in crying is a response to the stress experienced by the sympathetic nervous system of fight or flight. Another function increased by the sympathetic nervous system is breathing, which includes opening the throat by expanding the glottis to increase air flow. Following this sympathetic response, eventually the parasympathetic nervous system attempts to undo the response by decreasing high stress activities and increasing recuperative processes, which includes digestion, which requires closing the fully expanded glottis to prevent food from entering the larynx.People tend to remember the positive aspects of crying, and may create a link between other simultaneous positive events, such as resolving feelings of grief.Crying is the dropping of tears, or welling of tears in the eyes, in response to an emotional state or physical pain.The act of crying is a complex secretomotor phenomenon characterized by the shedding of tears from the lacrimal apparatus, without any irritation of the ocular structures, instead, giving a relief which protects from conjunctivitis.
