What is the primary role of negative feedback control loops in the endocrine system?
What is the primary role of negative feedback control loops in the endocrine system?
- To regulate physiological functions (correct)
- To eliminate the need for hormonal production
- To amplify hormonal signals for increased effect
- To completely cease hormone activity
How does hypersecretion of hormones typically occur?
How does hypersecretion of hormones typically occur?
- Through increased feedback regulation
- From loss of feedback regulation (correct)
- Due to a deficiency of hormone production
- As a result of target cell receptor dysfunction
What distinguishes the endocrine system from the nervous system in physiological responses?
What distinguishes the endocrine system from the nervous system in physiological responses?
- Nervous system responses are regulated only within local networks.
- Endocrine responses are slower but longer-lasting. (correct)
- Endocrine responses are faster and shorter-lasting.
- Nervous system responses produce greater amplification effects.
