The lumbar ganglia are paravertebral ganglia located in the inferior portion of the sympathetic trunk. The lumbar portion of the sympathetic trunk typically has 4 lumbar ganglia. The lumbar splanchnic nerves arise from the ganglia here, and contribute sympathetic efferent fibers to the nearby plexuses.

2023年8月8日 · In this article, the lumbar sympathetic chain is discussed in detail below. Location and relations: It presents four interconnected ganglia, on either side. Lumbar sympathetic chain lies anterolateral to the bodies of lumbar vertebrae, …

Discover the complex function of lumbar paravertebral ganglia in the human nervous system.

2023年10月30日 · 23 pairs of ganglia can be found: 3 in the cervical region (which fuse to create the superior, middle and inferior cervical ganglions), 12 in the thoracic region, 4 in the lumbar region, four in the sacral region, and a single, and the unpaired ganglion impar mentioned above.

The lumbar ganglia are a group of four interconnected ganglia forming the lumbar part of the sympathetic chain. They are situated along the anterolateral surfaces of lumbar vertebral bodies, deep to the medial aspect of psoas major muscle, on either side.

The sympathetic chain ganglia constitute a row of ganglia along the vertebral column that receive central input from the lateral horn of the thoracic and upper lumbar spinal cord. At the superior end of the chain ganglia are three paravertebral ganglia in the cervical region.

In the context of Neuroscience, 'Lumbar Ganglia' refers to the clusters of nerve cell bodies located along the lumbar sympathetic trunk, which play a role in distributing postganglionic fibers to the lumbar spinal nerves.

There are typically four sympathetic chain ganglia found at lumbar vertebral levels. They are known as lumbar paravertebral ganglia. The neurons in these ganglia are postganglionic sympathetic neurons that synapse with axons from preganglionic sympathetic neurons.

In the horizontal plane, the ganglia lay from 0 to 0.5 cm posterior to the anterior border of the third lumbar vertebra and 1.8 to 3.0 cm laterally from the center of the third lumbar vertebra. The sympathetic chain always lay anterior to the psoas muscle.
