Which of the following receive innervation from general visceral efferent fibers?

General visceral efferent fibers (GVE) are part of the autonomic nervous system, which controls involuntary body functions. These fibers carry motor signals from the central nervous system to various organs and glands in the body.

The structures that receive innervation from GVE fibers include:

1. Smooth muscle: This type of muscle is found in the walls of organs and structures such as the esophagus, stomach, intestines, bronchi, uterus, urethra, blood vessels, and the iris of the eye. GVE fibers control the contraction and relaxation of these muscles.

2. Cardiac muscle: This is the muscle tissue of the heart. GVE fibers regulate the rate and force of heart contractions.

3. Glands: GVE fibers control the secretion of glands, including salivary glands, gastric glands, sweat glands, and others.

So, to answer your question, the structures that receive innervation from general visceral efferent fibers are smooth muscles, cardiac muscles, and glands.
