Spinal Cord

Not directly. Th spinal cord carries nerve signals to and from the brain. Some of those signals go to nerves that stimulate muscle movement.

Yes; the brain is part of the Central nervous system itself, and the spinal cord forms a part of the nervous tissue itself. It is all one continuous tissue.

there are different things which could cause tingling in the face, for example the tension associated with migraine can commonly cause numbness and tingling due to pressure.

The ependymal cells.

No you can not feel your toe.

I am a paraplegic and my spinal cord has been severed with my Thoracic 4, 5 & 6 vertebra were shattered in a car crash. (I am a T-4 Para) I can't feel my toes, or my feet or anything below my chest.

Even though I still have 3% of the nerves connected I do not have sensation. I used to have phantom sensnsation thinking could feel my toes, but when I close my eyes I couldn't tell when someone touched my feet.

The Autonomic nervous system which controls breathing, heartbeat, blood pressure, & blinking and other reflexes is still connected. It's you "Auto" matic nerves. A condition known as autonomic dysreflexia can cause problems if the spinal cord is severed above T-3. I can even cause a severse stroke as your blood pressure can rise out of control if you bend your leg in an awkward position, get an infection or caused by other continuos pain.

Usually, this refers to an Anterior Cruciate Ligament tear, where the knee is in a fixed position and a twisting force is applied to it. This manifests itself as knee weakness when weight is put on it, with the sensation of the knee "slipping" forward. Damage of the meniscal cartilage around it is also common.

In the young or active athlete, ACL repair is surgically undertaken using a tendon graft to repair the ligament. In the not so active, the quadriceps muscles supporting the knee can be built up through physiotherapy and so surgery can be avoided.

Myelitis is inflammation of the spinal cord or of the bone marrow

The cervical curvature is the most superior spinal curvature.

We certainly do have a lot of nerves in our bodies. Far too many for anyone to count. Most of them are so tiny that you can't see them at all, but the ones that you can see are a very pale yellow, almost white!

The spinal cord is made up of nerve tissue. This is a thick bundle of neurons that runs through the spinal canal or the vertebral column. The vertebral column is the tower of vertebral bones typically called the "spine" by laymen. The spine is in fact the amalgamation of the two. In other words the spine is the vertebral column with the nervous spinal cord running through it.

I had a herniated disk at C5 C6. My symptoms started out as just an aching in between my shoulder blades. Over a period of about 2 weeks it progressivly got worse, the pain became so bad in my neck, shoulders and down my arm I would sit up and cry at night. I couldn't get rid of the pain till I had surgery. My disc was herniated into my spinal cord which was causing impingement. I had alot of numbness, tingling, pins and needles all over my body. The pain was unbearable!

The somatic nervous system, which is part of the peripheral nervous system, delivers motor and sensory information along the central nervous system- essentially connecting things like the skin nerves to the brain.

The cerebellum connects the cerebrum and the spinal cord.

afferent nerves

Beetles and other insects are invertebrates which mean that they do not have a spine and/or backbone. The spinal cord is a bundle of tissues and cells and it is the center of the nervous system. The spinal cord extends from the brain and connects to the spine. The beetle exoskeleton is made of hard plates and the body is three different parts; the head, the thorax, and the abdomen. But the beetle as well as other insects have a ventral nerve cord.similar to the human spinal cord.

Our spinal cord protects the nerves that send messages to the brain. It is made up of a series of connected bones or vertebrae. These vertebrae are stacked on top of each other forming an ‘S’ shape with the curve being the most at the neck and in the lower back. Each vertebra has a disc between them which acts as a shock absorber. Unfortunately, though there are situations where the spine can be injured and needs surgery.

Causes for spinal cord injuries can be aging, lack of exercise, and overuse of the affected joint.

There are different ways in which spinal fixation is approached. Some approach it from the back of the spine, known as Posterior Lumbar Interbody Fusion while some approach it from the side known as Transforaminal Lumbar Interbody Fusion. Both methods can be used depending on the patients’ medical history.

Ranka Hospital, Pune provides treatment for spinal cord injuries.

The H-shaped grey matter of the spinal cord contains motor neurons that control movement, smaller interneurons that handle communication within and between the segments of the spinal cord, and cells that receive sensory signals and then send information up to centers in the brain.

In human anatomy the spinal column has been divided into four sections for reference and specificity; the cervical spine, the thoracic spine, the lumbar spine and the sacral spine. The Cervical Spine is the section in the neck area comprised of seven vertebrae starting at the base of the skull and counting down the spine. To refer to the individual vertebrae in that area you would again start at the base of the skull with C1, and then count down to the last cervical vetebra, C7. The cervical spine is made up of C1, C2, C3, C4, C5, C6, and C7. The Thoracic Spine is the next section down the back located in the chest area and is comprised of twelve vetebrae. The ribs connect to the thoracic spine and create a strong skeletal structure that protects the vital organs. The vertebrae in the thoracic spine start with the eighth vertebra down which is called T1 and continued through T12. The third major region of the spine, the Lumbar Spine,starts below the thoracic spine with the thirteenth vertebra, L1, and continues through L5 for most people, although it is not uncommon for some people to have a sixth Lumbar verterbra, L6. When you have a low backache, it is usually in the area of the Lumbar Spine since it is the part of the vertebral column that supports most of the body's weight. The final section of the spine continues from the last lumbar vertebra, number seventeen (or eighteen, if there are six in this section) and down to the pelvis. This is called the Sacral Spine and has only one vertebra, the sacrum, called S1, and the coccyx bone which is also known as the tail bone. The sacrum and coccyx are uniquely shaped.

The cerebrospinal nervous system consists of the brain, spinal cord and the peripheral nerves given off by these to the outer parts of the body. 31 pairs of nerves emerge from the spinal cord. Each nerve has 2 roots - 1 anterior(at the front of the spine) and 1 posterior (at the back of the spine) carrying sensory nerves. Motor nerves carry impulses to the muscles, & have the responsibility for bodily movement. On the other hand, sensory nerves are responsible for carrying sensory impulses which provide the brain with information about sensation i.e. hot and cold.

It is called the central commissure. Some also call it the Grey Commisure.

well, from what i know from my previous studies and witnesses. there are quite lots of ways to prevent serious cordial injuries in the spine depending on the place and how it was injured. first of all, the victim i.e. it could be anyone should develop or have a good and healthy way of living, indulging oneself in lots of exercises would do a great good to the spine. also one should try ones best to be extremely flexible in such an area as it increases the regenerative ability of the inter-vertebral discs that are located in between each spinal vertebra. another way is DO NOT SMOKE or take in HARD DRUGS. they weaken the bones thus reducing their ability to protect the internal organ which is the cord itself. having a very nutritive diet would help too. lots of milk and vegetables with (sometimes) calcium pills e.g SANDOZ tablets as supplements. always visit the doctor to see how you are performing with your body. ensure that you are physically fit at all times. Although i am just a student writing, i do believe that if you take this advise seriously be sure of recovering from any spinal injury. just stick tothe rules and be wise when driving. well, from what i know from my previous studies and witnesses. there are quite lots of ways to prevent serious cordial injuries in the spine depending on the place and how it was injured. first of all, the victim i.e. it could be anyone should develop or have a good and healthy way of living, indulging oneself in lots of exercises would do a great good to the spine. also one should try ones best to be extremely flexible in such an area as it increases the regenerative ability of the inter-vertebral discs that are located in between each spinal vertebra. another way is DO NOT SMOKE or take in HARD DRUGS. they weaken the bones thus reducing their ability to protect the internal organ which is the cord itself. having a very nutritive diet would help too. lots of milk and vegetables with (sometimes) calcium pills e.g SANDOZ tablets as supplements. always visit the doctor to see how you are performing with your body. ensure that you are physically fit at all times.

my apologies your answer was correct i missread it

peripheral nervous system, or PNS, consists of the nerves outside the cns.

No, not all animals have spinal cords. Only vertebrates have spinal cords.

(However, their are plenty of spineless people and they are vertebrates)
