The nerve pathway travels down from the s1 spine. If the nerve root at the s1 is impinged or herniated, symptoms of sciatica can appear.
nerve my a$$ nerve
starting in the spinal cord, trace a motor pathway to the adductor muscles of the thigh. Include the spinal cord root, spinal nerve, nerve plexus, and specific peripheral nerve involved in the pathway
that's because god made us like that. no im kidding, but it is true, but anyway, we have a nerve pathway because we do!:p
peripheral nerve system
The optic nerve (cranial nerve II) carries sensory information about light intensity to the brain as part of the afferent pathway in the pupillary reflex.
the common peroneal nerve and the tibial nerve:Common Peroneal Nerve, comprised of nerve fibers from L5, S1, S2, and S3.Tibial Nerve comprised of nerve fibers from L4, L5, S1, S2 and S3)
The nerves coming off the spinal cord at L5 and S1 are being pushed out of their normal position.
A contralateral motor pathway is a neutral pathway located at the opposite side of the brain. It is on the eighth nerve of the cochlear nucleus.
It means that the disc between L5-S1 has protruded out to one side (not centrally), and is affecting (most likely compressing) the S1 nerve root which is below the level of the herniation (the L5 nerve root has already exited the IVF). From this report I am assuming you are having some sensory or motor problems in your lower limbs?!
When the S1 nerve is pinched, pain can be felt in the lower back, buttocks, back of the thigh, calf, outside edge of the foot, and in some cases, the little toe. This type of pain is known as sciatica and can be sharp, shooting, or burning in nature.
Evidence of impression on the L5 and S1 nerve root on the right at the L5-S1 level typically includes imaging findings such as a herniated disc, foraminal stenosis, or a mass effect from adjacent structures. On MRI, this may present as displacement or compression of the nerve roots, along with associated edema or inflammation in the surrounding tissues. Clinical symptoms may also be evident, including radicular pain, numbness, or weakness in the lower extremity corresponding to the affected nerve roots.
