Ganglion cells in the lateral cricoarytenoid muscle of the normal adult rat. A light microscopic study

The innervation of the lateral cricoarytenoid muscle was examined using light microscopy. Some ganglion cells are considered to enter the muscle, accompanied by branched nerves. These findings suggest that, in the rat lateral cricoarytenoid muscle, intramuscular ganglion cells exist and may be involved in innervating and contracting smooth muscle cells of the arterioles, thus regulating the blood flow or intravascular pressure.
