baroreceptor (C2)
noun
Pronunciation: /ˌbæroʊrɪˈsɛptər/
Definition
A specialized nerve ending that detects changes in blood pressure and sends signals to the brain to regulate heart rate and vascular resistance.
Examples
The baroreceptor reflex is essential for maintaining stable blood pressure during sudden posture changes.
When blood pressure drops, the baroreceptor activity decreases, triggering the heart to beat faster.
Chronic hypertension can eventually cause the baroreceptor sensitivity to reset to a higher, less healthy level.
