Compared to neurotransmitters, hormones act:
Correct answer: C. For a shorter period of time
- A. Faster
- B. On fewer cells
- C. For a shorter period of time
- D. Over longer distances
Explanation
Hormones typically act for shorter periods of time compared to neurotransmitters due to their mode of transportation and action. Hormones are released into the bloodstream and travel throughout the body, leading to a widespread but slower onset of action. In contrast, neurotransmitters act locally at synapses, facilitating rapid communication between neurons. Additionally, hormones are subject to rapid degradation and clearance from the bloodstream, limiting their duration of action compared to neurotransmitters, which can be rapidly recycled or broken down.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
