Visceral innervation involves which type of innervation?

• A. It involves bilateral innervation by the ANS via visceral afferents
• B. It involves unilateral innervation by somatic nerves
• C. It is always fast and localized
• D. It is only from skin

Answer: (A)

Visceral innervation is carried by the autonomic nervous system, which supplies the internal organs with both motor control to smooth muscle and glands and sensory input via visceral afferents. Because the ANS operates on both sides of the body to regulate internal functions, this innervation is bilateral rather than unilateral. In contrast to somatic nerves, which relate to skin and skeletal muscle and tend to produce fast, well-localized sensations, visceral afferents convey diffuse, often poorly localized signals from the organs. Therefore, the correct description is bilateral innervation by the ANS via visceral afferents.
