Summary Introduction
Introduction:
The lumbar plexus starts from the T12 to L4 of the ventral rami of the spinal nerve. It supplies the lower limbs and the pelvic girdle. Lumbar and sacral plexus are together called the lumbosacral plexus. The femoral nerve, femoral cutaneous nerve, and the genitofemoral nerve are the three important nerves of the lumbar plexus.

What is the function of the dorsal roots of the spinal cord?A. They receive sensory input.B. They control motor output.C. They convey information from the brain to the spinal cord.D. They convey information from the spinal cord to the brain.
Spinal nerves are called mixed nerves because they (a) are associated with a pair of dorsal root ganglia. (b) exit at intervertebral foramina. (c) contain sensory and motor fibers. (d) are associated with a pair of dorsal and ventral roots.
(a) What are the superior and inferior boundaries of the spinal cord in the vertebral canal? (b) A correctly executed lumbar spinal tap could poke the cauda equina or filum terminale, but not the conus medullaris. Explain.
