Crying is the shedding of tears in response to an emotional state. The act of crying has been defined as "a complex secretomotor phenomenon characterized by the shedding of tears from the lacrimal apparatus, without any irritation of the ocular structures".<ref>{{#invoke:Citation/CS1|citation |CitationClass=journal }} Quoted by Michelle C.P. Hendriks, A.J.J.M. Vingerhoets in Crying: is it beneficial for one's well-being?</ref> A related medical term is lacrimation, which also refers to non-emotional shedding of tears. Crying is also known as weeping, wailing, whimpering, and bawling.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

For crying to be described as sobbing, it usually has to be accompanied by a set of other symptoms, such as slow but erratic inhalation, occasional instances of breath holding and muscular tremor.

A neuronal connection between the lacrimal gland (tear duct) and the areas of the human brain involved with emotion has been established.
