Explanation:
Detailed explanation-1: -In contrast to the body’s response to a nerve impulse, hormones usually cause a slower, but longer lasting, response. For example, the brain sends a signal to an endocrine gland to release adrenaline into the bloodstream. When the adrenaline reaches the heart, it makes the heart beat more rapidly.
Detailed explanation-2: -Hormones bring about their characteristic effects on target cells by modifying cellular activity. Protein hormones react with receptors on the surface of the cell, and the sequence of events that results in hormone action is relatively rapid.
