Answer:
The signs of inflammation that are associated with histamine release is the expression of redness, heat, swelling, and pain.
Explanation:
The basophil- mast cell product, histamine, is a part of the innate immune mechanism in the body of higher animals to fight foreign agents. Since these molecules are kind of protective measures in the body, they do not lead to loss of function of the affected part where they are localized, however, they do increase the vasodilation and permeability of the blood vessels to white blood cells, mainly neutrophils and macrophages to fight microbes, and consequently lead to swelling, redness, heat and pain which can also be due to the secretion of bradykinin. Therefore, inflammation due to histamine is associated with option E.

The correct answers are option 2, 4 and 6
Explanation:
2-The T tubules are the extensions of the cell membrane that goes deep into the center of the middle of the skeletal and cardiac muscles and are in close contact with the sarcoplasmic reticulum.
These tubes plays 2 vital functions in connecting an action potential to muscle contraction. T tubules causes the action potential from the plasma membrane into the interior of the muscle cell through voltage-gated Na+ and K+ channels.
An action potential causes the opening and closing of Calcium channels in the sarcoplasmic reticulum. The resulting change in cytosolic Ca2+ concentration triggers contraction of the myofibrils.
The T tubules play two important roles in linking an action potential to muscle contraction.
