Spinal Cord
The spinal cord is long, cylindrical rod present inside the neural canal of vertebral column. It is a part of central nervous system and controls reflex actions of the body.

The spinal cord is a collection of nerves, surrounded and protected by bone (the spine). Muscles attach to the spine to maintain posture and the integrity of the system.
The spinal cord connects the brain to the body. It allows the brain to send and receive signals to and from organs and tissue all throughout the body.
What is involved in spinal decompression therapy?
Spinal decompression therapy will help you lengthen and strengthen your spinal cord. This should allow you to walk better and recover from a major spinal injury.
What is complete acute spinal cord injury involving c5?
There are two types of spinal cord injuries. Complete spinal cord injuries refer to the types of injuries that result in complete loss of function below the level of the injury, while incomplete spinal cord injuries are those that result in some sensation and feeling below the point of injury. The level and degree of function in incomplete injuries is highly individual, and is dependent upon the way in which the spinal cord has been damaged. Complete spinal cord injuries result in complete paraplegia or complete tetraplegia. Complete paraplegia is described as permanent loss of motor and nerve function at T1 level or below, resulting in loss of sensation and movement in the legs, bowel, bladder, and sexual region. Arms and hands retain normal function. Some people with complete paraplegia have partial trunk movement, allowing them to stand or walk short distances with assistive equipment. In the majority of cases, complete paraplegics choose to get around via a self-propelled wheelchair. Complete tetraplegia is characterized by the loss of hand and arm movement as well. Some tetraplegics require ventilator systems in order to breathe. Depending upon the location of the injury, some tetraplegics may have some arm and hand movement present. http://www.brainandspinalcord.org/spinal-cord-injuries/index.html
Level of Injury: Doctors and specialists use the level of injury to most accurately predict which parts of the body are most likely to be affected by loss of movement and sensation. Complete injuries will result in total loss of movement and sensation below the point of injury, while incomplete injuries will result in some degree of loss of movement and sensation below the point of injury. Levels of injury are classified as: • Neck
• C-1 to C-4
• C-5
• C-6
• C-7 and T-1
• T-1 to T-8
• T-9 to T-12 http://www.brainandspinalcord.org/spinal-cord-injury/index.html
This may be done to improve posture, increase ability to ventilate the lungs, prevent pain, or treat spinal instability and reduce the risk of nerve damage.
What disassembly found that the power cord of Apple HomePod mini is also not removable?
iBee Parts - Professional Factory Supplier For iPhone Samsung Huawei LCD Screen & Battery Repair Parts Replacement.
Apple's newly released HomePod mini uses a USB-C power cord that can be plugged into a separate power adapter. Some people speculate that the power cord can be removed, but this is not the case. Follow this article to find out!
MacRumors forum member ouimetnick discovered during disassembly that the power cord cannot be taken out, and if it is removed, it cannot be replaced.
It is understood that the standard HomePod is also equipped with a wire that cannot be removed, but technically it can be pulled out with sufficient strength and then reconnected. This does not seem to be the case with HomePod mini, and trying to remove the cable may cause damage to the speaker.
The disassembly also showed the built-in S5 chip that powers the device. Of course, ordinary users are not recommended to open the HomePod mini.

Will spinal cord compression put you in a wheelchair?
I had a ACD with Fusion in 2008. I have always had pains since which have gotten worse over the last year. I have had MRI march this year which showed normal. I have had shooting pains in my brain for few weeks now. So question is, have the nerves been pinched, compressed further up. Regards Debbie

Do memory foam pillows help keep the spine in alignment while sleeping?
Memory foam pillows do indeed keep the spine in alignment while sleeping as being kept at the head does this exact thing to the rest of the body. It is quite a miraclious invention.
That means there is a bulging disc that is impinging on the central canal (spinal cord) between the vertebral bodies at the C6-C7 levels, which may or may not be symptomatic.
Schwann cells (PNS)
If the ventral roots are destroyed can impulses reach the spinal cord?
In short, Yes.
A majority of the "signals" that travel through the ventral roots are motor "signals" going out to the periphery from the spinal cord. As such, the signals have already "reached" the spinal cord from the brain or another region of the spinal cord.
Thus, A ventral root lesion will interrupt signals from reaching the periphery.

What spinal segment structure carries non-myelinated GVE fibers?
The white ramus communicans carries non-myelinated GVE fibers.
The blank are carried to the brain and spinal cord by nerves?
i would say that blank is "messages" or electrical impulses.
peripheral nerves
What happens if the spinal cord does not work properly?
there would be difficulty in standing upright and walking of any living organism that can move
When the disc is properly positioned are the spinal cord or peripheral nerves impaired in any way?
no they aren't impaired
This sounds almost like a trick question from a diagnostic standpoint.
If the fibrous disc material, called the annulus fibrosus, that is located between two spinal bones, called vertebrae, are normal and healthy then there is little reason to think that the disc tissue it self could compromise or impair the nearby spinal cord or roots of the spinal nerves. Meaning that if the disc tissue is normal and healthy then by itself it would not likely pose a problem to the nearby nerve tissue.
However, there is more that could potentially harm or impair the spinal cord or nerve roots than just the spinal disc.
A few things that might pose a risk to the spinal cord and nerve roots other than a bulged or herniated disc:
- Spinal stenosis
- Spinal arthritis
- Spinal dysarticulation or subluxation
- Spinal fracture
- Spinal trauma
- Facet hypertrophy
- Muscle spasm
- Congenital anamoly
Can you talk with one vocal cord?
I don't think you can talk with one vocal cord, since whenever you speak, the vocal cords are come together and vibrate. If you only had one, the other one would need something to vibrate against to produce sound.
