Ventricular syncytium
 |
The ventricular syncytium is a network of cardiac muscle cells connected by gap junctions.
Purpose[edit | edit source]
Because of the connected nature of the syncytium with gap juctions, the heart muscle is able to have a coordinated contraction of the ventricles.
Types[edit | edit source]
There are two syncytia of the heart:
- The ventricular syncytium and the
- The atrial syncytium
Both of these are separated by fibrous tissue.
Control[edit | edit source]
Cardiac muscle, found in the walls of the heart, is partly under control of the autonomic nervous system.
Cardiac muscle[edit | edit source]
The cardiac muscle cell has one central nucleus, like smooth muscle, but it also is striated, like skeletal muscle.
Contraction[edit | edit source]
The contraction of cardiac muscle is involuntary, strong, and rhythmical.
