Nerve (Definition)

The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more

Each peripheral nerve provides what innervation to peripheral structures.?

Good question: I wish I could remember. When I have a question about that, I get out my old anatomy book from med school and look it up. The book is 1100 pages long. I refer to it frequently when I want to relearn what peripheral nerve innervates what structure. For laypeople I recommend Frank Netter's Atlas of Human Anatomy. It's available from Amazon. ...Read more

How many genito femoral nerves innervate the cremaster muscle?A single nerve or multiple?

A nerve: The genitofemoral nerve is a single nerve, about the diameter of a piece of spaghetti. It splits into a genital branch and a femoral branch. In males, the genital branch innervates the cremaster muscle and part of the scrotal skin. As with most nerves large enough to have a name, it is composed of a bunch of nerve fibers, also known as axons. ...Read more

Nerve damage after recent dental implants (Inferior Alveolar Nerve)?

Nerve damage after recent dental implants (Inferior Alveolar Nerve)?

Question ?: If you have damage, see the Surgeon. Sometimes this can be helped by removing the implant if it is impinging on the nerve or the proximal space. Sometimes it is inflammation and can be resolved with time and medication. See the Oral Surgeon and get a CT scan to evaluate. It is a risk and occasionally happens, but most often is resolved. Good Luck. ...Read more

Posterior left disc herniation 6.3x10.5mm impinging on the left s1 nerve root also a degree of narrowing of the left neural foramen impinging L5 nerve?

Disc protrusion: The L5-S1 disc is very susceptible to protrusion since it gets more load than most other lumbar discs. The disc is impinging on the nerve roots as they exits the spinal canal. Your neurologist might suggest conservative approaches like muscle strengthening exercises & physical therapy to help address your pain. http://www.nlm.nih.gov/medlineplus/herniateddisk.html ...Read more

Does migraine affect the trigeminal nerve?

Does migraine affect the  trigeminal nerve?

Migraines: The function of the trigeminal nerve should remain normal in patients with migraines ( good facial sensation and good masseter muscle strength). However, it is the trigeminal nerve the main neural structure implied in the mechanism of migraine. A cascade of neuro-inflammatory response on the trigeminal nerve is what ultimately mediates the pain in migraine sufferers. ...Read more

Trigeminal nerve: The most common form of paroxysmal orofacial pain is trigeminal neuralgia. Typically, a pain attack is accompanied by tic-like cramps or involuntary spasms of the facial muscles ("tic douloureux"), and often leads to a complaint of muscle pain. See a neurologist for evaluation, tests, imaging and treatment. ...Read more

Can Maxalt (rizatriptan) work on the Trigeminal Nerve?

For migraine...: ...there are theories that the trigeminal nerve is involved. Maxalt (rizatriptan) works to decrease and stop abnormal firing and release of certain chemicals that cause the migraine pain. For the more typical trigeminal disease, trigeminal neuralgia, Maxalt (rizatriptan) does not have any effect because the mechanism of pain is different. Good question! ...Read more

Are both cluster headaches and migraines related to the trigeminal nerve? If so, how are they related? How does the trigeminal nerve affect one's head

Superb questions!: You are apparently young and smart. This could be a good research project for you. Cluster headache, like trigeminal neuralgia, produces what is called a "neuralgiform" pain syndrome (no space for details). Migraine is different. But both are neurological syndromes. The exact biological differences are poorly defined. "Cortical spreading depression" is more typical of migraine. ...Read more

Abbreviation "lpr?": Sorry, I'm not understanding what you are trying to ask with the abbreviation "lpr." There are known relationships between the trigeminal nerve and certain forms of headaches. There are also ASSOCIATIONS between GERD and migraines, however, the mechansim of cause and effect remains under discussion. Medications used to treat GERD can cause severe headaches as well...consider that...All the best. ...Read more
