The lumbar plexus is an important network of nerves that originates primarily from the lumbar spinal cord.
Understanding the Lumbar Plexus
The lumbar plexus is essentially a "web" or network of nerves. According to the provided reference, this network is formed just to the side of where the spinal nerves T12-L5 exit the spinal cord through the intervertebral foramina. This area serves as a crucial point for nerve distribution to the lower limbs and pelvic region.
Key Features of the Lumbar Plexus
- Nerve Origin: Arises from spinal nerves T12-L5.
- Location: Situated lateral to the intervertebral foramina of the lumbar spine.
- Structure: A network (plexus) of interconnected nerve fibers.
- Function: Distributes nerves to the lower limbs and pelvic region.
