Figure 6.12: Somatic and Autonomic Efferents

Figure 6.12 A: An illustration depicts the somatic efferents that arise from the ventral horn and pass through the ventral root, spinal nerve, and skeletal muscle.An illustration depicts the somatic efferents that arise from the ventral horn and pass through the ventral root, spinal nerve, and skeletal muscle. Figure 6.12 B: An illustration depicts the sympathetic efferent, which arises from the intermediolateral nucleus through preganglionic fibers from white ramus. The sympathetic efferent pair with postganglionic fibers in the gray ramus forming sympathetic chain ganglion and reaches the skeletal muscle through prevertebral ganglion. Figure 6.12 C: An illustration depicts the parasympathetic efferent, which arises from the sacral parasympathetic nuclei and passes through preganglionic fiber and postganglionic fiber to reach the terminal ganglion near the end organ.
