Doctor insights on:
Sensory Nerve Action Potential
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 moreSee 1 more doctor answer
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
Location: Pain refers to different areas.Get a more detailed answer ›
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 moreSee 1 more doctor answer
Concerning lateral pterygoid muscle,why protrusive action functions to test intactness of mandibular nerve?
Lateral pterygoid: The motor function of the mandibular branch of the fifth cranial nerve is tested by asking the patient to clench their teeth together and to open their mouth against resistance. The "thumb" test is the only reliable test to examine lateral pterygoid muscle. ...Read moreSee 1 more doctor answer
Pinched lumbar nerves. Any negative side effects to long term mechanized traction to relieve pinch nerve?
No, not Realy: As long as mechanical stretch gives you productive hours in your day, it is a good technique. If you forgo stretch of your legs, conditioning and strengthening exercise you will not achieve full recovery. When you know you have bad discs, avoid prolonged sitting, driving, and jarring sports which lead to chronic facet problems (arthritis) in the back. Inversion techniques / yoga mimic traction. ...Read moreSee 2 more doctor answers

Image guided cervicothoracic sym. Ganglion block along with t.N block most likely will help your pain , is relatively low risk procedure in trained hands. ...Read moreSee 2 more doctor answers
Injury location: Although specific sensory branches go to skin and motor branches go to muscle, the main nerve trunks contain both. These large cables split off smaller branches that contain only sensory or motor nerve cells. If an injury occurs on the skin, sensantion nearby is affected. If a small motor nerve is injured, nearby muscles are paralyzed. But if a large nerve is injured, both can occur. ...Read moreSee 1 more doctor answer
Brain not affected: Given the types of TOPICAL TAGS I see you have used for this question the short answer is NO. There is absolutely no relationship between penile "nerve" damage as you state and some type of future dysfunction of the brain in terms of a functional or neurodegenerative order. ...Read more
Is ilioinguinal nerve the same size as sciatic nerve?Saw mr neurography image of the sciatic nerve.Can ilioinguinal nerve appear that clearly on mrn?
Not likely: The sciatic nerve is anatomically larger than the ilioinguinal nerve. Mrn is not widely available. The ilioinguinal nerve is not as likely to be seen as clearly on mrn as the sciatic nerve. ...Read more
Possibly: Nerve injury implies some kind of damage to the nerve itself. While spinal cord and nerves are both nervous tissue, nerves typically are structures that have branched outside the spinal cord. Injury to the sciatic nerve, for example, is not considered a spinal cord injury. They are very different structures. ...Read moreSee 1 more doctor answer
Can the ilioinguinal nerve and genital branch of genitofemoral nerve be evaluated by MRI for any problems?
Here are some...: Why do you raise this Q? Any concern after a surgery should be evaluated with detailed history to specify the features of symptoms with clear sequence of events + properly physical exam so to define what you felt & concerned after surgery is related with surgery itself or just lingering effect of healing process. For possible injury to nerve, all imaging studies are useless. So, faithfully work... ...Read moreSee 1 more doctor answer
Is there a connection between vagus nerve irritation (causing hiccuping) and dementia?
What are causes of vagus nerve irritation?
Not directly: Elderly people may suffer both, but they are not related. Damage to the nerve can result from injuries or even some surgeries. Aging alone can impair it to some degree. Discuss this w/ your doctor so you'll understand better about your condition and what to expect (or not). Best! ...Read more
