Firstly, what is the sciatic nerve? Here is a brief anatomy lesson for you! The sciatic nerve is a major nerve of the lower limb. It is a thick rope like band approximately 2cm wide, which makes it one of the largest nerves in the body. The sciatic nerve derives from the spinal cord in the lower back. It stems from several nerve roots (L4-S3) which then come together to form the sciatic nerve and enters the gluteal region. It then travels down the back of the thigh, and as it reaches the back of the knee it then splits into two separate nerves called the tibial and common peroneal nerves. Two of the main roles for the sciatic nerve or any nerve is to supply motor (movement) and sensory (sensation) functions. The sciatic nerve innervates muscles of the leg to allow movement and sensation for the lower leg and foot.
