Compare And Contrast Meninges Of Spinal Cord And Brain
I've heard that the brain, spinal cord and other central nervous system tissue is where mad cow disease is found. Would steak be ok to eat?
Well... muscles cont: Contain nerves. I would not eat any part of the cow that had mad cow. But... Eating the brain and spinal cord or tail (which contains the spinal cord) would obviously be worse than a slice of steak. ...Read more
No: Spinal cord injury affects portions of the body b elow the site of the injury. The brain is not affected, but these injuries are frequently very disturbing and sometimes dangerous. The person suffering from this can be depressed and needing of assistance in many other ways. ...Read moreSee 2 more doctor answers
Can't answer: Specifically. Evaluation for tumor and infection would be reasonable reasons. Certain congenital issues such as chiari malformations would also prompt these studies. ...Read more
Go to ER now: An infection of the area surrounding the brain can cause meningitis- fever, stiff neck, headache, and changes in conciousness. An infection within the brain itself is encephalitis- causing changes in personality, level of conciousness, and even seizures or other abnormal movements. These conditions are both very life-threatening, but treatable, and should be evaluated by a physician immediately. ...Read more
Menigeal: Carcinomatosis (if a cancer) or lymphomtous or leukemic menigitis. The former carries a poor prognosis. It is addressed in children with cranio-spinal irradiation and intr-thecal chemotherapy. In adults with solid tumors, it is a mark of quite advanced disease, causes cranial neuropathy, and weakness. Rarely only site of disease. ...Read more
Medulloblastoma: Medulloblastoma is a tumor that sheds cells which can float throughout the spinal fluid space around the brain and spinal cord. If the tumor sheds these cells then they can migrate anywhere along the brain and spinal cord. ...Read more
Fiberoptic cables: Like phone cords, the brain connects down through the brainstem by tracts like fiberoptic cables connecting the motor/sensory areas of the brain to the areas of the spinal cord sending out nerves to your body. Long and very complex but wonderfully made! ...Read more
Not quite correct: For years, it was felt that nerve cells would not heal. If the cell body dies (apoptosis), it does not resurrect. If the nerve fibre axon is transected, it will not reconnect. But the myelin covering can regenerate, and the brain can employ alternative pathway connections with time. ...Read more
Almost correct: The gray matter (nervous system tissue with cell bodies) is inside the cord, surrounded by white matter (axons: nerve fibers going to & from the brain). While there is gray matter on the surface of the brain, it is also present in collections deep inside the brain. The organization of the central nervous system is quite complex. ...Read more
Glutamate receptors: Glutamate is the major excitatory neurotransmitter in the cns, and could be expressed elsewhere in body, but the receptor description used above is designed to study brain pathways pre-dominantly, and has not be studied extensively othewise. Nmda antagonism is mechanism of several drugs, but to date, no successful ampa agonist. ...Read more
Can MS show lesions only in the brain and not in the spinal cord? And what type of MS would this be?
See below: If you have optic neuritis and suspicious lesions in the brain, you have a very high chance of having multiple sclerosis. The absence of lesions in spinal cord is not exclusionary. Although other disorders may cause your issues, would get diagnosis confirmed, and start a potent MS agent ASAP, if that seems to be answer. ...Read more
Can MS lesions be just in spinal cord not brain or visa versa? Also does MS always show up in spinal fluid?
Good questions: MS lesions may either be in the brain or the spinal cord, or in both. Sometimes, rarely, they are not found in either location. Evidence does not always appear in the spinal fluid. These are not perfect tests, but in most cases, they will help give the answer. ...Read moreSee 3 more doctor answers
If a neurological examination is normal, do that mean that there is no problem with your brain and spinal cord?
Neuro exam: That is normal is a very good thing. If you still have symptoms consider a second opinion w/another doctor. Also look into natural and non-invasive treatments if doc is ok w/them. A health psychologist will know about them. Peace and good health. ...Read more
Does happen: Far less common presentation, but several patients may have initial lesions in spinal cord. However, here's the main challenge: a condition called neuro-myelitis optica might present this way also, and the drugs for ms would make things worse, so get an aquaporin 4 study to make things more precise. ...Read more
Prion: Prions are proteins that have changed conformation, so that the normal function of the protein inside the cells won't work. The prions' also causes other normal proteins to misfold and make more prions, spreading the process. The prions affect many cells in the body, but they particularly harm nerve cells in the brain, causing progressive rapid degeneration. They are not alive, and have no dna. ...Read more
How do people get paralyzed below the waist? Is the cause from a nerve in the brain or spinal cord?
Spinal cord: This is from a spinal cord injury in the thoracic spine. ...Read more
