-
striated muscle tissue
muscle tissue characterized by transverse stripes
-
cardiac muscle, heart muscle
the muscle tissue of the heart; adapted to continued rhythmic contraction
-
smooth muscle
muscle tissue that does not appear striated under the microscope; has the form of thin layers or sheets
-
SA node, cardiac pacemaker, pacemaker, sinoatrial node
a specialized bit of heart tissue that controls the heartbeat
-
papillary muscle
any of several muscles associated with the atrioventricular valves
-
atrioventricular bundle, atrioventricular trunk, bundle of His, truncus atrioventricularis
a bundle of modified heart muscle that transmits the cardiac impulse from the atrioventricular node to the ventricles causing them to contract
-
atrioventricular node
a node of specialized heart muscle located in the septal wall of the right atrium; receives impulses from the sinoatrial node and transmits them to atrioventricular bundle
-
myocardium
the middle muscular layer of the heart wall
-
Purkinje fiber
a specialized cardiac muscle fiber that is part of the Purkinje network
-
Purkinje network, Purkinje's system, Purkinje's tissue
a network of Purkinje fibers that carry the cardiac impulse from the atrioventricular node to the ventricles of the heart and causes them to contract
