The bundle of His is a part of the electrical system of the heart. It is a collection of cells that carry electrical signals from the AV node to the bundle branches. The electrical system that controls the heartbeat is made up of several parts that signal the heart muscle to contract. ...

Gln2, Leu-7 and HNK-1 share the same spatio–temporal pattern, including the cells of the AV node and AV bundle from early stages onward, e.g., from the moment the first signs of formation of the ventricular septum are visible (4–5 weeks human, rat E11). The pattern shows the pr...
InWilhelm His …muscle fibres (known as the bundle of His) running along the muscular partition between the left and right chambers of the heart. He found that these fibres help communicate a single rhythm of contraction to all parts of the heart. ...
An electron microscope study of the atrioventricular node and the bundle of His was done after an in vivo fixation. Three types of cells have been described: (1) pacemaker cells localized in the atrioventricular node and the upper parts of both branches, (2) conduction, or "transitional" ...
A bundle of nerve fibers immediately surrounding the gray matter of the spinal cord. It is divided into three regions, the anterior, lateral, and posterior bundles, which lie in the corresponding funiculi. bundle of His bundle of His
Electrical signals in the heart are sent via conducting cells. The bundle of His comprises nerve fibers that stretch from the atrioventricular node to the Purkinje fibers. Bundle of His can also be called the atrioventricular bundle. The atrioventricular node sends an electrical signal to the ...

The bundle of His works in conjunction with the S-A node, S-A meaning sinoatrial; the A-V node, A-V meaning atrioventricular; bundle branches; and Purkinje fibers to set the pace of the heart. This is all facilitated by the pacemaker cells, which are made up of specialized heart ...
