What is the difference in a bush cord of wood and a cord of wood?
a cord of wood is 4ftx8ft by 16 inches deep a bush cord is 4ftx8ftx4ft
Does the nerve going to the eyebrow go to the spinal cord?
There are 31 pairs of spinal nerves which originate in the spinal cord. There are twelve cranial nerves, which are referred to by Roman numerals. Ten of the twelve cranial nerves originate from the brainstem; the other two stem from the forebrain and thalamus.
The nerve that is responsible for eyebrow movement is the VII cranial nerve, also known as the facial nerve. This is one of the ten cranial nerves originating from the brainstem.
How many pairs of spinal nerves are in the spinal cord?

The human peripheral nervous system has 31 pairs of spinal nerves.

It could be a mumber of things but I advise getting checked by Dr. or medical clinic
Where can someone find information about Spinal Disk replacement?
The best way to find out needed info on spinal disk replacement is to schedule an appointment with you orthopedic specialist. Otherwise you can check out organizations online such as Spine Health, Spine Universe, Ortho Info, or the Mayo Clinic. Information can also be found via your local hospital.
Is the largest part of the nervous system that involves the brain and spinal cord?
the largest part of the nervous system is the peripheral nervous system (PNS) which includes all nerves in all parts of the body except the brain and spinal cord.
Opening providing for exit of spinal nerves?
Intervertebral foramina.
The left an right pedicles have notches on their inferior and superior surfaces that create openings, the intervertebral foramina, for spinal nerves to leave the spinal cord between adjacent vertebra.

The foramen magnum is where the spinal cord enters the cranial cavity.

What part of the spinal cord is in charge for pain and temperature?
Incoming pain, temperature and crude touch sensations from the body enters the spinal cord via pseudounipolar neurons through the posterior rootlets of each spinal nerve. Once entering the spinal cord, these neurons travel up and down 1-2 vertebral segments within the dorsal lateral tract (tract of lissauer) before they synapse onto secondary neurons. The secondary neurons cross to the other side of the spinal cord (decussate) through the anterior white commissure, and then travel up to the brainstem within the spinothalamic tract. Once in the brainstem, these neurons synapse onto the thalamus at various nuclei. From the thalamus, this sensory information is sent to various regions of the brain where it is interpreted consiously.
Pain, temperature and crude touch sensation from the face follows a similar route, except that the secondary neurons travel to the thalamus within the contralateral trigeminal lemniscus.
Why would one vocal cord quit working my left vocal cord is not moving.?
I had this problem about 25 years ago....before widespread use of CAT scans and before the invention of the MRI A small tumor, a hamartoma, was found after extensive X rays in the musculature controlling the vocal cord I had surgery to remove it with good results. Later, I experienced serious voice weakness, as there may have been damage in the imprecise effort to excise the tumor. There was significant dyssymmetry in the vocal cord movement. The doctors could never could determine the reason, except the surgery damage theory. I had medialization thyroplasty to "shim" the weaker vocal cord toward the mid-line with good results. At present, I have a strong voice but this is because each morning I inhale water in the shower to "wash off" the vocal cords. In other words, the acccumulation of phlegm overnight is not moved away normally by my vocal cord movement---so I do it artificially with the hot shower water. After my experience, I am convinced that quite a number of people to not have perfect vocal cord symmetry. Beware, many speech therapists and EMTs are not very aware of these procedures I recommend contact with Dr. Albert Merati at the University of Washington Roger in Wichita
Spina bifida is a congenital defect that occurs when a small part of the spinal cord along with its meninges are exposed.
What forms the content of the central canal in the spinal cord?
Ependymal cells line the central canal of the spinal cord
Is tethered spinal cord and AVM the same?
== == No.
AVM: arteriovenous malformation, which is basically veins or arteries that are not properly formed. This is extremely rare and symptoms don't usually show until the patient is in his/her 30's
Tethered Spinal Cord: A disorder caused by tissue attachments that limit the movement of the cord within the column. Causes abnormal stretching of the spinal cord.
How many segments make up your entire spinal cord?
The spine consist of 24 moving segments plus the sacrum and the coccyx.
Is the spinal cord made out of bone?
The human spinal cord is protected by the bony spinal column. The spinal column is made up of bones called vertebrae. The spinal cord itself is made of neurons, similar to the brain itself.
How are cerebral cavernous malformations diagnosed?
Cerebral cavernous malformations are usually diagnosed by computerized axial tomography (CAT) scan or, more accurately, a magnetic resonance imaging (MRI) scan with gradient echo sequencing.
