How do tears come about?

Post by schizophrenicsinner » Fri Aug 04, 2006 4:18 pm

:) Is it biological to cry? If so, how? With which glands, etc. ? How do our emotions work with tears? Thanks! A curious one! :twisted:

Is it biological? :shock: They come from our tear ducts. Tears can clean our eyes. We cry when we're sad probably to show others as a form of non-verbal communication. Tears also get rid of excess hormones produced due to our emotional state

There's not such a thing as a Science, right? Is there? They must have ideas on that subject, no?

tears are produces as a response to the stimulation of the brain through the parasympathetic nervous system of the tear glands.they are produced by a classical cellular secretion by Golgi vesicles.
