BIOXI18: BODY FLUIDS AND CIRCULATION

339458 Neural signal through the sympathetic nervous (part of ANS) increases the cardiac output because of

1 Increasing the rate of heartbeat
2 Increasing the strength of atrial contraction
3 1 and 2
4 Decreasing the speed of conduction
BIOXI18: BODY FLUIDS AND CIRCULATION

339459 Cardiac centre can moderate the cardiac functions through

1 Sympathetic nervous system only
2 Parasympathetic nervous system only
3 Autonomic nervous system (ANS)
4 CNS only
BIOXI18: BODY FLUIDS AND CIRCULATION

339460 Statement A :
Human heart is called myogenic because it is autoregulated by specialized nodal tissue called SA node.
Statement B :
A special neural centre in the medulla oblongata can moderate the cardiac function through autonomic nervous system.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
BIOXI18: BODY FLUIDS AND CIRCULATION

339461 Statement A :
Neural signals through the sympathetic nerves can decrease the rate of heartbeat, the strength of ventricular contraction.
Statement B :
Parasympathetic neural signals increase the rate of heartbeat, speed of conduction of action potential and thereby the cardiac output.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
