translation icon : beta-adrenoceptor
  • Activation of the beta-adrenoceptor increases heart rate and promotes blood vessel dilation during physical activity.

Examples

  • The drug targets the beta-adrenoceptor to reduce high blood pressure.

  • The beta-adrenoceptor plays a crucial role in regulating heart rate.

  • Activation of the beta-adrenoceptor increases the heart rate during stress.

  • Scientists studied how the beta-adrenoceptor mediates different responses in cardiac tissue.

  • Researchers are studying how beta-adrenoceptors affect blood pressure.

  • The beta-adrenoceptor is essential for the body's response to stress, as it influences heart rate and circulation.

  • Inhibiting the beta-adrenoceptor can lead to lower heart rates, making it a target for treating cardiovascular diseases.

Morphology

beta-adrenoceptor = adrenoceptor (semi-transparent) = beta + adreno + receptor

The structure 'beta-' + 'adrenoceptor' is clear, but 'adreno-' is a specialized combining form (from adrenaline) and may be unfamiliar to average learners.

Etymology

Beta-adrenoceptor breaks into three parts: beta meaning 'second', a Greek letter used to name types; adreno- which links to adrenaline, the body chemical that speeds the heart; and receptor, a 'receiver' that gets signals. So a beta-adrenoceptor is a receptor that 'receives' signals from beta-type adrenaline-like chemicals and helps change heart rate and the size of blood vessels.
