Give reason : (a) If neural connection...

Give reason :
(a) If neural connection of heart is severed then the mammalian heart will continue beating or not?
(b) If symathetic control to the heart is re - established in such case what will happen?
(c ) If parasympathetic control to the heart is re - established then what will happen?

Text Solution

Verified by Experts

(a) Yes, the mammalian heart will continue beating because the mammalian heart is myogenic in which the cardiac muscles fibres are produced spontaneously without requiring stimulation from nerve cells.
(b) If sympathetic control is re - established, heartbeat will increase because of the release of nor - adrenaline from sympathetic nervous system (SNS).
(c ) If parasympathetic control is re - established the heartbeat will become normal because of the release of acetylchloine from parasympathetic nervous system (PSNS) which decrease the heartbeat.

Reason : It gives important information concerning the spread of excitation to the different parts of heart and it is of value in the diagnosis of cases of abnormal cardiac rhythm and myocadial damage.

Reason : This happens because of the absence of heart in the prawn.

    In this question below is given a passage followed by several inferences. you have to examine each inference seperately in the context of the passage and decide upon its degree of truth or falsity. Mark your answr as : (a) If the inference is definitely true i.e. it direclty follows from the facts given in the passage (b) if the inference is probably true though out definitely true in the light of the facts given (c] If you think the data are inadequate from the facts given you can not say whether the inference is likely to be true or false . (d) If you think the inference is probably false though out definitely false in the light of the facts given (e) If you think the inference is definitely false i.e. it contradicts the given facts A radical new surgery procedure laughed at not long a go is holding out fresh hope of patients of cardiac myopathy or enlargement of the heart . The technique now in india allows patients to go home two weeks after the operation to lead a near normal sedentary life. Cardiac myopathy is a condition that has a variety for causative factors. An attack from one of the 20 identified viruses parasite infection long term alcohol abuse and blood pressure could bring it on and in rare cases it could follow child birth and is even known to run in families.The condition is marked by an increase in the size of the heart's chambers and a decrease in the efficiency of pumping. The efficiency of the heart is inversely proptional to the size of the heart.
