Release of the chemical histamine causes?
Release of histamine causes dilation of blood vessels, increased vascular permeability, and smooth muscle contraction. This can result in symptoms such as itching, redness, swelling, and bronchoconstriction depending on the location of release and the receptors it activates.
Can itching be caused by toxic release of some sort?
Yes. Usually it is caused by a histamine reaction from the body' immune system.
Can narcotics abuse cause itching?

How cold ice induce histamine release?
Ice can induce histamine release by causing the blood vessels in the skin to constrict, leading to a rapid rewarming process when the skin is rewarmed. This rapid rewarming can trigger the release of histamine from mast cells in the skin, leading to itching, redness, and swelling at the site of contact with ice.
What cells release histamine How does the body respond to the release of histamine?
Mast cells and basophils release histamine. When histamine is released, it causes blood vessels to dilate, which can lead to symptoms such as redness and swelling (inflammation), increased mucus production, and smooth muscle contraction, resulting in symptoms like itching and bronchoconstriction.
What cells of the dermis release histamine and play a role in the hypersensitivity reactions of the skin?
Mast cells are the cells of the dermis that release histamine and play a crucial role in hypersensitivity reactions of the skin. Histamine release from mast cells can trigger allergic responses and inflammation in the skin, leading to symptoms like redness, itching, and swelling.
What is produced when inflexible dry or cracked skin cells release histamine as they are tugged which sets off a nerve ending?
The release of histamine from dry or cracked skin cells when tugged can activate nerve endings, leading to sensations of itching or discomfort. This process can trigger an inflammatory response, further exacerbating skin irritation and potentially leading to increased dryness and cracking.
What do basophils release?
Histamine and heparin
What cause skin allergy?
The release of histamine causes the itching. Hence the use of "antihistamines" to get rid of the itching.
What cells produce histamine?
Mast cells are the primary cells that produce and release histamine. Histamine is stored in granules within mast cells and is released in response to allergens and other triggers, leading to symptoms of allergy such as itching, sneezing, and swelling.
What cause the skin to itch?
Usually itching is caused by the release of histamine as part of an immune response, either an inappropriate response to proteins in the environment (i.e. allergies) or to a parasitic infection.
