What is nervus Ischiadicus?

Anatomical terms of neuroanatomy. The sciatic nerve, also called the ischiadic nerve, is a large nerve in humans and other vertebrate animals which is the largest branch of the sacral plexus and runs alongside the hip joint and down the lower limb.

Does the sciatic nerve affect the knee?

The sciatic nerve extends from your toes all the way up to your lower back. Because this critical nerve travels through the back of your knee and controls muscles in that area, problems with it often lead to knee pain.

What are the symptoms of sciatica of the knee?

• Weakness while extending the knee (attempting to straighten your leg)

Where does the sciatic nerve run down the leg?

The sciatic nerve runs from the back, under the buttock, and downward through the hip area into each leg.

Is Piriformis a muscle?

The piriformis muscle is a flat, band-like muscle located in the buttocks near the top of the hip joint. This muscle is important in lower body movement because it stabilizes the hip joint and lifts and rotates the thigh away from the body.

Where does the nerve to the biceps femoris come from?

The nerve to the short head of the Biceps femoris comes from the common peroneal part of the sciatic, while the other muscular branches arise from the tibial portion, as may be seen in those cases where there is a high division of the sciatic nerve.

Where does the sciatic nerve meet the spinal Rami?

It is formed from both anterior and posterior divisions of the anterior (ventral) rami of spinal nerves L4 through S3. The anterior branches of these five spinal nerves meet and converge in the posterior pelvic region  to form a single large nerve.

What are the symptoms of compression of the sciatic nerve?

Piriformis syndrome refers to compression of the sciatic nerve by the piriformis muscle. It is also known as deep gluteal syndrome. Clinical features include radicular pain, numbness, muscle weakness and buttock tenderness. The pain can occasionally be exacerbated by internal rotation of the lower limb at the hip.
