Question

The sciatic nerve is a combination of which two nerves?

1) pudendal and posterior femoral cutaneous
2) posterior femoral cutaneous and tibial
3) pudendal and common fibular
4) common fibular and tibial

Answer 1

The sciatic nerve is a combination of the tibial and common fibular nerves, extending from the sacral plexus through the hip and gluteal region into the leg.

Step-by-step explanation:

The sciatic nerve is a major systemic nerve originating from the sacral plexus, which includes parts of the lower lumbar and sacral spinal nerves. This significant nerve is a combination of two important nerves: the tibial and common fibular (also known as the peroneal nerve) nerves. The sciatic nerve extends across the hip joint, through the gluteal region and into the upper posterior leg, where it continues down to the lower leg and foot.
