Bundle Branches Page 12

• The Purkinje fibers from the Bundle of HIS divide into two main branches, the right(a) and left bundle(b) branches.
• These Purkinje fiber branches rapidly transmit depolarization waves to the ventricular muscle.

Terminal Purkinje Fibers Page 13

• Terminal Purkinje fibers(a) conduct depolarization impulses from the bundle branches(b) to cardiac muscle cells(c).
