Determining the exact number of nerves in the lower limb is complex, as individual nerve branches and variations exist. However, we can identify the major nerves that serve the lower limb. Based on the reference provided from UAMS Department of Neurobiology, some of the major nerves and their sources are outlined below:
Here's a breakdown of some key nerves of the lower limb:
| Nerve | Source |
|---|---|
| Saphenous n. | Femoral n. |
| Sciatic n. | Sacral plexus (ventral primary rami of spinal nerves L4-L5 and S1-S3) |
| Superficial fibular n. | Common fibular n. |
| Superior gluteal n. | Sacral plexus (ventral primary rami of spinal nerves L4-L5, S1) |
It's important to recognize that the sciatic nerve then branches into other nerves like the tibial and common fibular nerves, which further divide into smaller nerves. Therefore, instead of a single numerical answer, it is more accurate to identify the major nerves contributing to the innervation of the lower limb.
