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.

What in the body signals the spinal cord to initiate urination?
See also:The neural control of micturition. Clare J. Fowler, Derek Griffiths, and William C. de Groat. Published in final edited form in: Nat Rev Neurosci. 2008 Jun; 9(6): 453–466.
Quoted: "The neural pathways that control lower-urinary-tract function are organized as simple on–off switching circuits that maintain a reciprocal relationship between the urinary bladder and the urethral outlet. Storage reflexes are activated during bladder filling and are organized primarily in the spinal cord, whereas voiding is mediated by reflex mechanisms that are organized in the brain (FIG. 5)."
The part of a spinal nerve that contains only sensory neurons is the?
The part of a spinal nerve that contains only sensory neurons is called the ventral root. There's also the axons of motor neurons and axons of sensory neurons.
What is a movement caused by the spinal cord interpreting an impulse from sensory receptors?
a reflex
How does liofen xl 20 capsules works on body?
Liofen-XL 20 mg capsules work on the body by blocking equally polysynaptic as well as monosynaptic reflexes at spinal point.
No they don't. Only certain types of animals have backbones, not any plants.
How dangerous is it to remove a tumor from the spinal cord?
Removing a tumor from the spinal cord can be quite dangerous due to the delicate nature of spinal cord tissue and surrounding structures. Risks include potential nerve damage, which can lead to paralysis, loss of sensation, or bladder and bowel dysfunction. The complexity of the surgery also increases the likelihood of complications such as infection, bleeding, or spinal instability. Each case is unique, so the specific risks depend on the tumor's location, size, and the patient's overall health.
Spinocerebellar refers to pathways in the nervous system that connect the spinal cord to the cerebellum, which is involved in coordinating movement and balance. These pathways carry proprioceptive information, allowing the cerebellum to process body position and movement. Dysfunction in these pathways can lead to various disorders, often characterized by coordination and balance issues. Spinocerebellar ataxias are a group of genetic conditions that affect these pathways, leading to progressive motor impairment.
How would you describe the spinal cord?
The spinal cord is a bundle of nerves and, along with the brain, it makes up the central nervous system. Nerves carry messages through the spinal cord to the brain, allowing us to feel, taste, smell, see, and hear. Nerves also carry messages from the brain through the spinal cord and to the muscles, allowing us to move.

How can a person who has spinal cord damage at C6 still have control of his or her head and neck?
This is because the spinal cord injury is at one of the lower cervical vertebrae. The severity of the injury increases as the vertebrae get higher. Usually, damage to the cervical vertebrae results in some form of quadriplegia, depending on which vertebrae is damaged. C6 specifically, carries functions up to the wrist. That is, if C6 is damaged, individuals lose fine motor skills in the hands and below, but retain some wrist function.
In order to lose control of the head and neck, there must be damage of C2 or higher (which is most likely fatal, as injuries above C4 require a ventilator, as the person is no longer able to breathe on their own).
What part or parts of the body does the spinal cord make up?
um that's a toughie! the spinal cord and .......
What are the symptoms of vocal cord paralysis?
It's where at least one of your vocal cords can't move. It effects how you talk or sing. Your voice will be weak and airy.

How does the spinal cord serve as a relay station?
Transmits neural signals between the brain and the rest of the body.
The spine is divided in to different regions and then each vertebrae within that segment is numbered. The vertebrae in the neck are called cervical vertebrae and there are 7 of them. Therefore, a fracture of C6 is a fracture in the 6th cervical vertebrae (at the base of the neck).
What does a protrusion in C6 mean?
Sounds like a (1) bulging disc, or (2) herniated disc. The disk is a hard rubbery "shock absorber" located between each veterbrae. They have a tendency to bulge --like mashing a marshmellow--as we get older and the stretching of the nerve fibers within the disc can cause chronic pain. A herniation is where the disk bulges out in such a way that the part "bulging" puts pressure on a nerve root exiting between each vertebrae. This causes terrible pain to radiate down the arm, and if chronic can cause weakness (and waisting) in certain muscles in the arm on the affected side.
What would happen if there would be transection along the lumbar 4 5 and s1 of the spinal cord?
Some hip, knee and foot movement depending on the level of injury. The lower the injury, the more control over movement.
A manual wheelchair may be used for everyday living, with the ability to go over uneven ground.
Ability to transfer independently from bed to chair, and chair to car. It may be possible to transfer from floor to chair depending on upper body strength.
Depending on the level of injury, walking may be possible with assistance or aids. Walking will be slow and difficult though.

Where is T3 on spinal cord and how does work?
It is the third thoracic (chest) vertebrae where spinal cord nerves branch out to control functions in and around the chest. You also have cervical (Neck) and lumbar(lower back) vertebra.
I've got the same problem but with a right sided protrusion, my osteopath and sports rehab therapist are confident i can stabilise it with yoga, swimming and area specific strengthening exercises! will let you know....

What is the significance of fractures of the transverse L1 and L2 spinal processes?
I just had a volume rendered 3-D CT for my lower back and found to my surprise that my left L1 transverse process was in floating large and small chunks slowly descending through my abdomen, the left L-2 looks like a amateur welder welded it back-on (plain fracture). I can't recall any pain...but I did have 'idiomatic' pleurisy some years ago...perhaps that was it's 'referred pain'.
What does it mean when the brainstem moves and goes into the spinal cord?
It means you should call your doctor...
I have already seen my doctor, had an MRI (that's how I know about the brain stem. I saw my doctor today to review the results of the MRI, but he was very vague in his explanation and I left his office not knowing any more than when I walked in.
