The nodal musculature can generate action potentials only in response to external stimuli . III. The number of action potential that could be generated in a minute varies at different parts of the nodal system . IV. The SAN can generate the maximum number of action potential , i.e., 80-85 min^(-1)

(i) Human heart is an ectodermal derivative (ii) Mitral valve guards the opening between the right atrium and left ventricle (iii) SAN is located on the left upper corner of the right atrium (iv) Stroke volume xx Heart rate = Cardiac output.

Choose the correct option. (i) Human heart is ectodermal in origin. (ii) Mitral valve guards the opening between right atrium and left ventricle. (iii) SAN is located on the left upper corner of right atrium (iv) Stroke volume xx heart rate = Cardiac output

Read the statements regarding the cardiac system and choose the right option Human heart is an ectodermal derivative Mitral valve guards the opening between the right atrium and left ventricle SAN is located on the left upper corner of the right atrium Stroke volume xx Heart rate = Cardiac output

Assertion. The S-A node acts as pace maker. Reason. The S-A node is located in the wall of the right atrium near the interatrial septum.
