Histamine receptor discrepancy

How can the same H1 type receptors cause both smooth cell constriction (bonchoconstriction) and smooth cell relaxation (systemic vasodilatation)? Ca2+ signalling cause constriction. I think the vasodilatation is caused by the H2 receptors. Vasodilatation should be removed from the H1 part of the table. 193.6.168.249 (talk) 14:03, 16 December 2016 (UTC)[reply]

I’m new editor

Hi, Im student from Uskudar University. I edit this article (Histamine receptor) as an assignment for my course (recent development in biotechnology ). I already completed Wikipedia training modules to be proficient in Wikipedia editing. I would appreciate any support.
