What is nerve root effacement?

Nerve root effacement refers to nerve root compression. This is an issue where the root of the nerve is compressed into the spine before exiting it, which can cause some painful back symptoms.

How do you injure your spinal cord?

There are many ways to hurt your back. For those over the age of 50, bending over the wrong way or too often is especially dangerous because it stresses the bones of the back and spine.

Which nervous systeam includes the spinal cord and the brain?

The centeral nervous system contains the brain and the spinal cord.

What two regions is the spinal cord enlarged?

the spinal cord is enlarged at the region from where the plexus originate

so it is enlarged at the cervical from where the roots for brachial plexus originates the and thoracolumbar level where the cauda equina originates

Why are spinal cord injuries so serious?

Spinal cord injuries are serious because if they aren't treated correctly, they can leave someone paralyzed. The spine injury is one of the worst types of innjury because there is a very big possibily that you will never be able to walk again, as said earlier.

How spinal nerves connected to the spinal cord?

dorsal and ventral roots.
Each spinal nerve is attached to the spinal cord via 2 dorsal roots and 2 ventral roots. The term "spinal nerve" actually refers to the location where these 4 roots come together outside of the spinal cord.

Are chordates a central solid nerve cord?

Yes, chordate's nerve cord is hollow as opposed to animals that are non chordate with a nerve cord which are solid.

What is neuro foramina?

a neuroforamen is the tiny hole in the bone in a vertebra that allow the nerve endings from the spinal column to pass through in order to transmit signals to the brain from eternal or internal stimulus.

Oes nerves that carry stimuli lead to or away from the brain and spinal cord?

All the nerves in your body are connected to your spinal nerves which then send messages from different areas in your body up through your central nervous system to your brain. Ex: When you walk your nerves in your feet and legs send a message up into your spine to the brain. So the question isn't really carrying messages toward or away its that it sends messages back and forth through your spine actually.

What causes spinal fluid in blood?

Blood, as seen in subarachnoid hemorrhage. If its pathologically yellow due to the breakdown of hemoglobin in blood, its called xanthochromia.

What is a traumatic injury to the neck and spinal cord can result in?

A spinal cord injury can result in a loss of sensation and/or loss of function below the area of spinal cord injury.

The degree to which the body is affected, will depend how high up the spinal cord the injury occurs. If the injury is in the neck, cervical region, then the arms will also be affected, resulting in Quadriplegia.

What sense organ goes to the spinal cord before the brain?

This mainly happens in the case of a reflex action. The spine receives the information from the receptor and gives commands to the effector a fraction of a second before the brain registers the action.

This happens only with the sense of touch

What are the protective layers around the brain and spinal cord?

Pia Mater, Subarachnoid Space, Arachnoid Mater, Dura Mater, Crainum/Vertebral Bodies.

What is the definition of spinal meningitis?

What is Spinal Meningitis?

Meningitis is an infection that causes inflammation of the membranes covering the brain and spinal cord. Non-bacterial meningitis is often referred to as "aseptic meningitis." Bacterial meningitis may be referred to as "purulent meningitis."

Causes, incidence, and risk factorsThe most common causes of meningitis are viral infections that usually resolve without treatment. However, bacterial infections of the meninges are extremely serious illnesses, and may result in death or brain damage, even if treated. Meningitis is also caused by fungi, chemical irritation, drug allergies, and tumors. Types of Memingitis include:
  • Meningitis - cryptococcal
  • Syphilitic aseptic meningitis
  • Meningitis - H. influenza
  • Meningitis - meningococcal
  • Meningitis - pneumococcal
  • Meningitis - staphylococcal
  • Meningitis - tuberculosis
  • Aseptic meningitis
  • Meningitis gram negative
  • Carcinomatous meningitis (meningitis due to cancer)
  • Acute bacterial meningitis is a true medical emergency, and requires immediate hospital-based treatment. Bacterial strains that cause meningitis include Streptococcus pneumonia, Haemophilus influenza, Neisseria meningitides (meningococcus), Listeria monocytogenes, and many other types of bacteria. In the U.S. almost 20,000 cases of bacterial meningitis occur yearly.

Viral Meningitis is milder and occurs more often than bacterial meningitis. It usually develops in the late summer and early fall, often affects children and adults under 30. Seventy percent of the infections occur in children under the age of 5. Most Viral Meningitis is associated with enteroviruses, which are viruses that commonly cause intestinal illness.

However, many other types of viruses can also cause meningitis. For example, Viral Meningitis may occur as a complication in people with genital herpes. Recently, West Nile virus spread by mosquito bites has become a cause of Viral Meningitis in most of the U.S. In addition to causing Viral Meningitis, West Nile virus may cause encephalitis in some patients and a polio-like syndrome in others.

Spinal Meningitis Symptoms
  • Fever and chills
  • Severe headache
  • Nausea and vomiting
  • Stiff neck (meningismus)
  • Sensitivity to light (photophobia)
  • Mental status changes

Additional symptoms that may be associated with this disease:

  • Decreased consciousness
  • Rapid breathing
  • Agitation
  • Opisthotonos (severe neck stiffness, ultimately resulting in a characteristic arched posture-seen in infants or small children)
  • Bulging fontanelles (the soft spots in a baby's skull may bulge)
  • Poor feeding or irritability in children
  • Meningitis is an important cause of fever in newborn children. For this reason, a lumbar puncture is often done on newborns who have a fever of uncertain origin.
Signs and tests
  • Lumbar puncture with CSF glucose measurement and CSF cell count
  • Gram-stain and culture of CSF (cerebral spinal fluid)
  • Chest x-ray to look for other sites of infection
  • Head CT scan looking for hydrocephalus, abscess or deep swelling
Treatment of Spinal MeningitisAntibiotics will be prescribed for bacterial meningitis; the type will vary depending on the infecting organism. Antibiotics are not effective in Viral Meningitis. Treatment of secondary symptoms including brain swelling, shock, and seizures will require other medications and intravenous fluids. Hospitalization may be required depending on the severity of the illness and the needed treatment. Expectations (prognosis) of Spinal MeningitisEarly diagnosis and treatment of bacterial meningitis is essential to prevent permanent neurological or spinal damage. Viral Meningitis is typically not so serious, and symptoms should disappear within 2-weeks with no residual complications. Complications of Spinal Meningitis
  • Hearing loss or deafness
  • Brain damage
  • Loss of vision
  • Hydrocephalus
Calling your health care providerIf you feel that you or your child have symptoms suggestive of meningitis, you must seek emergency medical help immediately. Early treatment is key to a good outcome. Prevention of Spinal MeningitisHaemophilus vaccine (HiB vaccine) in children will help prevent one type of meningitis. The pneumococcal conjugate vaccine is now a routine childhood immunization and is very effective at preventing Pneumococcal Meningitis.

It's highly recommended household contacts and people with close contact with individuals with meningococcal meningitis receive preventative antibiotics to avoid becoming infected themselves.

Some communities conduct vaccination campaigns following an outbreak of meningococcal meningitis. Military recruits are routinely vaccinated against this form of meningitis because of its high rate of occurrence.

The American Academy of Pediatrics and the American College Health Assn encourage college students (particularly freshmen living in dorms) to consider being vaccinated with the meningococcal vaccine.

How to Deal with Spinal Meningitis?

With the arrival of late summer and early fall Spinal Meningitis raises its ugly head to search for preys, its victims are often children below five and adults below thirty. Spinal Meningitis is a lay-term for inflammation of the meninges-membranes covering the brain and spinal cord. It affects the brain and spine simultaneously.

Causes'Purulent Meningitis' refers to the infection caused by bacteria. 'Aseptic meningitis' is non bacterial meningitis- caused by virus, fungi, chemicals and tumors. SymptomsThe symptoms of both bacterial and non bacterial "spinal meningitis symptoms" are very similar. The onslaught of meningitis disease is preceded generally by a splitting headache, fever and chills, severe stiff neck, sensitivity to light, vomiting, loss of appetite, and sweating.

Bacterial Meningitis may show some extra symptoms like mental status changes, Dementia, twitching, perturbation, skin rashes and protrusive soft skull spots in case of babies.

DiagnosisIf you experience these symptoms seek medical attention right away. Delays can cause incurable secondary defects like blindness, deafness and brain damage or may be life threatening.

Common meningitis disease diagnosis tools the doctor uses for spinal meningitis include a Lumbar Puncture to inspect cerebrospinal fluid, bacterial culture, chest X-ray and a CT scan of the brain to locate meningitis disease damage.

Medical TreatmentBacterial Meningitis is treated with antibiotics administered orally first and then intraveinously. The earlier the disease is detected and treated the better will be the results. Although rarely seen, this form of Meningitis is more serious that than Viral Meningitis. Antibiotics can't cure Viral Meningitis. The disease usually resolves on its own. Secondary defects can be treated with intravenous fluids. Natural TreatmentGolden Seal is a natural tonic that strengthens the spinal nerves and prevents recurrence of spinal meningitis. Black Cohosh is good for spinal meningitis, but its use is unadvisable for pregnant women. Both these medicines should be taken only for short time periods.

Prevention is always better than cure. Thanks to administration of drugs and vaccines like Haemophilus vaccine, Meningococcal vaccine and Pneumococcal conjugate vaccine you can prevent some types of Spinal Meningitis.
