d. Termination
Frequently when H1 and H2 receptors C. Both types of receptors are distributed among many
are located on the same cells, they act different cells and are often present on the same cells and
in what fashion? may act in an antagonistic fashion. For instance,
a. Synergistically neutrophils express both types of receptors, with stimulation of H1
receptors
b. Additively
resulting in the augmentation of neutrophil chemotaxis
c. Antagonistically
and H2 stimulation resulting in its inhibition. The two
d. Agonistically
receptors do not act synergistically, additively, or
agonistically.
