Pain in back of upper thigh - under left buttock Sciatica is pain, tingling, or numbness produced by an irritation of the nerve roots that lead to the sciatic nerve.The sciatic nerve is formed by the nerve roots coming out of the spinal cord into the lower back.It goes down through the buttock, then its branches extend down the back of the leg to the ankle and foot.ymptoms of sciatica include pain that begins in your back or buttock and moves down your leg and may move into your foot. Weakness, tingling, or numbness in the leg may also occur. 1  Sitting, standing for a long time, and movements that cause the spine to flex (such as knee-to-chest exercises) may make symptoms worse.

Sciatic nerve The sciatic nerve branches into different parts of the body along its path, hence its ability to supply such a large area of the body. It is a mixed-function nerve, meaning that it contains both sensory neurons and motor neurons.

Sciatca - Causes and Treatment of Sciatica The sciatic nerve is the largest and longest nerve in the body. It runs from the lower back region through the buttock and continues down the back of the leg. The sciatic nerve controls the movement of many muscles in the thigh and leg as well as provides a means of sensory input to the brain.

Sciatic nerve The sciatic nerve (/ s aɪ ˈ æ t ɪ k /; also called ischiadic nerve, ischiatic nerve, butt nerve) is a large nerve in humans and animals. It begins in the lower back and runs through the buttock and down the lower limb. It is the longest and widest single nerve in the human body, going from the top of the leg to the foot on the posterior aspect.

What You Need to Know About Sciatica Sciatica symptoms occur when the large sciatic nerve is irritated or compressed in the lumbar spine. The sciatic nerve is the largest single nerve in the body and is composed of individual nerve roots that start by branching out from the spine in the lower back and combine to form the sciatic nerve..1  The sciatic nerve starts in the lower back at lumbar segment 3 (L3).he specific sciatica symptoms-the leg pain, numbness, tingling, weakness, and possibly symptoms that radiate into the foot-largely depend on where the nerve is pinched. For example, a lumbar segment 5 (L5) nerve impingement can cause weakness in extension of the big toe and potentially in the ankle.

The Sciatic Nerve The sciatic nerve innervates most of the hind limb. As is the case with many of the large nerves of the vertebrate nervous system, the sciatic nerve is a mixed-function nerve, meaning it is made up of the axons of sensory and motor neurons. The sciatic nerve gives rise to branches as it progresses distally along the hind limb.

Sciatica Medical Definition of Sciatic nerve. Sciatic nerve: The largest nerve in the body, the sciatic nerve begins from nerve roots in the lumbar part of the spinal cord (in the low back) and extends through the buttock area to send nerve endings down to the legs.

The Sciatic Nerve Although the sciatic nerve passes through the gluteal region, it does not innervate any muscles there. However, the sciatic nerve does directly innervate the muscles in the posterior compartment of the thigh, and the hamstring portion of the adductor magnus. The sciatic nerve also indirectly innervates several other muscles, via its two terminal branches:

Where in the Spine does the Sciatic Nerve Originate? The Sciatic Nerve. The sciatic nerve actually originates from several nerve “roots” along the spine collectively known as the lumbosacral plexus. This means it is made up of several spinal nerves whose roots come out from the spine from L4 through S3.These spinal nerves come together to form the sciatic nerve, which is the largest nerve in the body. From the lower back, the sciatic nerve follows the back of each thigh down to each foot.It connects the spine directly to the muscles in the feet and legs.This one very important nerve is responsible for delivering nerve signals to most of the lower half of the body.he Sciatic Nerve.

Sciatca - Causes and Treatment of Sciatica If you have pain extending from your back or buttock and traveling down your leg into your calf, you may have a condition called sciatica. If you do, learning about sciatica and your physical therapy treatment options can help you recover quickly. The sciatic nerve is the largest and longest nerve in the body. It runs from the lower back region through the buttock and continues down the back of the leg. 1  The sciatic nerve controls the movement of many muscles in the thigh and leg as well as provides a means of sensory input to the brain. When the sciatic nerve becomes irritated and inflamed, it results in sciatica. Sciatica is a common cause of low back pain and leg pain. It is usually caused by pressure on the sciatic nerve from a herniated disc.

There may also be weakness, numbness, tingling, particularly in the leg and/or foot. The location of the pain and/or numbness varies according to the location that the sciatic nerve or nerve root is affected. The pain can range from burning to aching and can vary in intensity. The pain may be intermittent or constant.

Sciatica Causes and Treatment The diagnosis of sciatica means that there is irritation of the sciatic nerve. The sciatic nerve transfers information to and from your brain. The brain sends messages to the muscles, and the nerve transmits signals back about pain and sensations. The sciatic nerve is quite large, in fact, it is the largest peripheral nerve in the body.

- Sciatic nerve pain can be so excruciating and debilitating that you don’t even want to get off the couch. Common causes of sciatica can include a ruptured disk, a narrowing of the spine canal called spinal stenosis, and injury. The sciatic nerve runs down the spine and branches off, like a zipper, down the legs. The pain of pressure on the sciatic can feel like sharp shocks running down your leg (generally just one at a time) or nagging lower back pain. Sometimes people experience numbness or tingling in the leg, too.

Sciatic nerve The sciatic nerve is the dominant nerve that innervates the lower back and the lower extremities. It travels from the lower spine, through the pelvis, and down each leg. It is the longest and widest nerve in the human body. The sciatic nerve primarily supplies the muscles of the lower leg, including the calf, ankle, and the back portion of the knee. It also supplies sensation to the sole of the foot, the ankle, the entire lower leg, and the back of the thigh. The sciatic nerve branches into different parts of the body along its path, hence its ability to supply such a large area of the body.

- The sciatic nerve supplies sensation to almost all major muscle groups in the lower leg. The femoral nerve supplies sensation to the muscles in the front of the thigh down to the knee. Irritation or trauma to these nerves could produce hip pain that travels down the leg.
