Muscle fascicle
Introduction
Overview
Overview
In anatomy, a fascicle is a bundle of skeletal muscle fibers surrounded by connective tissue.
Specialized muscle fibers in the heart which transmit electrical impulses from the Atrioventricular Node (AV Node) to the Purkinje Fibers are fascicles, also referred to as bundle branches. These start as a single fascicle of fibers at the AV node called the Bundle of His that then splits into three bundle branches: the right fascicular branch, left anterior fascicular branch, and left posterior fascicular branch.
