Which of the following is not true for histamine ?
Correct answer: B. causes bronchodialtion
- A. Causes arteriolar dialation
- B. causes bronchodialtion
- C. Causes pain when injected subcutaneously
- D. Is released following injury and in certain allergic responses
Explanation
Histamine causes arteriolar vasodilation, produces pain when injected intradermally or subcutaneously, and is released in injury and allergy. It causes bronchoconstriction, not bronchodilation, so option b is the false statement.
