Which term does not apply to human heart? a. Neurogenic b. Pacemaker c. Four chambered d. Mitral valve
Option A.A neurogenic heart is the one in which impulses are originated by nerves. This type of heart is present in cockroach and some invertebrates. Human heart is myogenic which means that impulses are originated by muscles. The SA node in human heart is called pacemaker as it initiates and maintains the rhythmic contraction of heart. Human heart is four chambered consisting of 2 auricles and 2 ventricles. Mitral valve is also known as bicuspid valve and present between left atrium and left ventricle. Hence, neurogenic heart does not apply to human heart.
