Paralysis is a symptom of a problem, not a disease itself.
The underlying problem which causes it might be hereditary (genetic, such as an evolving case of multiple sclerosis). Or, of course paralysis can be caused by injury to the spinal cord. In this latter case, your preventative measures would be things like wearing a helmet when cycling. Genetic issues cannot be prevented.
What forms the white matter in the spinal cord?
myelinated axons the grey matter are the cell bodies . . . which is logical when you think about it the axons need to be on the outside of the spinal cord so they can extend to all the other parts of the body to carry sensory information.
Do snakes have a spinal column?
Like all reptiles snakes do have a spinal column and a skeletal structure.
What two tracts do the spinal cord have?
ascending (sensory/afferent) and descending (efferent/motor) tracts.
Addition: Other than these two types of tracts, the white matter of spinal cord also contains "associative tracts" containing short ascending and descending fibres which coordinate the function of the different regions of spinal cord.
Which of these protect the spinal cord as it extends down the back from the medulla?
The Dura, Arachnoid, and the Pia Mater (the meninges)
What are the nerves outside the brain and spinal cord?
The peripheral nervous system contains all the nerves in the body that lie outside of the spinal cord and brain.
They communicate with the central nervous system to make sure our body parts, such as our fingers, can send signals to the central nervous system for processing in our brains.
Why is it important to destroy the brain and spinal cord of a frog before conducting an experiment?
So the frog does not feel pain and it also prevents reflexs movements such as hopping.
IS spinal cord is encased in bones called vertebrae to help protect it?
yes it is encased to keep for any mishaps occurring and damaging the spinal cortex:)))
What does the spinal nerve do?
Spinal nerves are pain receptors that carry signals to the brain when pain is felt.
vocal cords create your voice by vibrating, and in so doing, they alter the pressure of the air at audio frequencies. We call this variation in air pressure Sound.
Does ecstasy deplete your spinal fluid?
No, that is just a popular ecstasy myth. Ecstasy (MDMA) releases Serotonin in the brain which makes you happy. Other things that could be laced with the ecstasy (ie: Meth, Speed, Caffeine, MDA, MDEA, or BZP) also don't release spinal fluid.
However you could hurt your back because your dancing all night. :)
What are symptoms of spinal arachnoidits?
Typical symptoms of spinal arachnoiditis include back pain that increases with activity, pain in one or both legs or feet, and sensory abnormalities of some type, usually involving decreased reflexes.
Usually they are simply called nerves. Depending on the scenario, sometimes they are called nerve tracts or pathways.
How does the spinal cord function in maintaining homeostasis?
it sends messages to the brain to keep it healthy now i told you fools the dang on answer now stop searching and go get a life you don't need to be on the net go and do something
, wow that's just dang rude you should be ashamed maybe that person is in calss teying to look up answers!
Which spinal cord plexus supplies the abdominal wall?
The lumbar plexus supplies the abdominal wall, external genitals, and part of the lower limbs. Arising from this plexus are the ilioinguinal, femoral, and obturator nerves.
No. It's a structure, consisting mainly of parts of two "organs"; the central nervous system and the skeleton.
What neurons that carry impulse to the brain and spinal cord called?
These are called efferent neurons. The one that carry impulses away are afferent. Afferent (A) are away (A).
What is the membrane that covers the spinal cord?
The meninges (from the Greek meninx, meaning "membrane") cover and protect the brain and spinal cord. The meninges have three layers: 1) the dura mater, 2) the arachnoid, and 3) the pia mater. The dura mater is the outermost layer covering the central nervous system. The arachnoid (from the Greek arachne, meaning "spider") is a web-like network of collagen and elastic fibers. The innermost layer of the meninges is the pia mater. The pia mater is firmly attached to the neural tissue of the spinal cord and brain. Cerebrospinal fluid fills the space between the pia matter and the arachnoid membrane. Most of the blood vessels that supply blood to the central nervous system are in the pia mater.
