Question

the type of innervation that refers to the fact that many structures in the body are innervated by nerve fibers from both the sympathetic and parasympathetic divisions of the ans is called innervation. What is the dual innervation of the ANS?

Answer 1

Dual innervation refers to the phenomenon wherein organs receive nerve fibers from both the sympathetic and parasympathetic divisions of the autonomic nervous system, helping to maintain homeostasis through opposing effects.

Step-by-step explanation:

The concept being asked about is known as dual innervation of the autonomic nervous system (ANS), which is a crucial aspect of physiological regulation. Dual innervation refers to when organs are supplied by both sympathetic and parasympathetic nerves, often exerting opposing effects to maintain homeostasis. An example is the heart, where the sympathetic nervous system increases heart rate and the parasympathetic nervous system decreases it. This balance ensures proper function of the body's organs and is vital for everyday and emergency responses.
