Answer 2

Answer :-

Myogenic Heart :-

■ In "Myogenic Heart", the contractions are initiated by a special node of modified cardiac muscles called "Sino-Atrial node" (SA node).

■ Examples :-

• Hearts of "Vertebrates"

• Hearts of "Tunicates"

• Hearts of "Molluscs"

Neurogenic Heart :-

■ In "Neurogenic Heart", the contractions are initiated by a nerve ganglion, situated in the vicinity of the heart.

■ Examples :-

• Invertebrates like anthropods (Cockroach)

• Some annelids (Earthworm)

Extra Information :-

~~~~~~~~~~~~~~~~~~~

☆ Acetylcholine secreted by the nerve ending accelerates the neurogenic heartbeat.

☆ In neurogenic heart, the heartbeats originate by nevous stimulation.

☆ If the nerve supply of the hearts of vertebrates is cut off or even removed from the body, it continues to beat.
