How crustacean heart differs from human's?
1. Open and closed circulatory
2. Myogenic (human) and neurogenic (crustacean) heartbeat
Neurogenic vs. Myogenic
The cardiac muscle possesses automaticity and
contract spontaneously. A myogenic heart is capable of generating a cardiac
contraction independent of nervous input.
A neurogenic heart requires nervous input
Crustacean cardiac ganglion is a cluster of
neurons on the heart wall and produces rhythmic motor output for the heartbeat.
