Final answer:
The correct option is 'b. Dilation of blood vessels leading to the skeletal muscles' since epinephrine typically prioritizes vasoconstriction in high levels, although at lower levels it can cause vasodilation. The correct answer is option b.
Step-by-step explanation:
Epinephrine (adrenaline) typically elicits a sympathetic response by binding to adrenergic receptors on various cell types. This can result in increased heart rate, increased blood glucose levels, and increased respiration, facilitating the fight-or-flight response. Adrenergic receptors are classified as α-adrenergic and β-adrenergic, where α-adrenergic receptors when activated typically cause vasoconstriction, and β-adrenergic receptors are associated with vasodilation and other metabolic effects.
Given these effects, the option that would NOT be an expected outcome of epinephrine binding to adrenergic receptors is the dilation of blood vessels leading to the skeletal muscles, as in high enough levels, epinephrine will prioritize vasoconstriction over vasodilation. However, this is somewhat complex since lower levels of epinephrine can actually promote vasodilation. Nonetheless, in the context of the question set and given options, the correct option in the final answer is b. Dilation of blood vessels leading to the skeletal muscles.
