Innervation of the heart

This anatomy tutorial by Kenhub covers the innervation of the heart, focusing on the roles of afferent and efferent fibers, as well as the sympathetic and parasympathetic fibers. The cardiac plexus, a key structure in heart innervation, is discussed in detail, highlighting its location and function. The tutorial explains how parasympathetic fibers from the vagus nerve decrease heart rate and contraction force, while sympathetic fibers from the thoracic spinal cord increase these functions. The video concludes with suggestions for further learning through Kenhub's resources.
