Question

"Dual innervation" refers to an organ receiving

A) two nerves from the spinal cord.
B) both autonomic and somatomotor nerves.
C) both sympathetic and parasympathetic nerves.
D) nerves from both the brain and the spinal cord.
E) None of the answers are correct.

Answer 1

Dual innervation is when an organ is innervated by both the sympathetic and parasympathetic nervous systems to regulate its activity and maintain homeostasis(option c).

Step-by-step explanation:

Dual innervation refers to the phenomenon where an organ receives innervation from both the sympathetic and parasympathetic nervous systems, which are two divisions of the autonomic nervous system(option c).

These two systems often work in opposition to each other to maintain homeostasis within the body. For example, the heart receives this kind of dual innervation; the sympathetic nerves increase the heart rate, while the parasympathetic nerves decrease it.
