The rate of heartbeat is regulated by the integrated activity of inhibiting and accelerating effects occuring in which part of the brain ?A. CerebellumB. DiencephalonC. Medula oblongataD. Pons Vorolii |
Answer» Correct Answer - C A special neutral centre in the medulla oblongata can moderate the cardiac function through autonomic nervous system (ANS). Neutral signals through the sympathetic nerves (part of ANS) can increase the rate of heartbeat, the strength of ventricular contraction and thereby the cardiac output. On the other hand, parasympathetic neutral signals (another component of ANS) decrease the rate of heartbeat, speed of conduction of action potential and thereby the cardiac output. |

Erythroblastosis foetalis occurs: |
Answer» A protein named as rhesus antigen, is present on the surface of red blood corpuscIes. The population having this protein are called Rh positive `(RH^+)` while others who do not have this protein are known as Rh negative `(Rh^-)` (dominant). Erythroblastosis Foetalis occurs due to Rh incompatibility between the foetus and mother during pregnancy. Rh antigen of the foetus do not get exposed to the `Rh^-` blood of the mother in the first pregnancy. However, during the delivery of the first child, there is a possibility of exposure of the maternal blood to small amounts of the `Rh^+` blood from the foetus. In such cases, the mother starts preparing antibodies against Rh antigen in her blood and during her subsequent pregnancies the Rh antibodies from the mother (Rh-ve) leak into the blood of the foetus (Rh + ve) resulting in the destruction of foeta| RBCs. This could be fatal to the foetus or could cause severe anaemia and jaundice , even may lead to the death of the foetus. |
