When was the first spinal cord discovered?
Herophilus coined the term "spinal cord" around 200 BC. Galen more formally documented the spinal structures through anatomical studies in the second century A.D.
Where is the T1 and T2 on the spinal cord?
T1 and T2 refer to the first and second thoraxic vertebrae. They are the 8th and 9th vertebrae, starting from the top.
Your MRI showed you have a syrinx in the distal end of your spinal cord what does that mean?
Syringomyelia is a disorder in which a cyst forms within the spinal cord. This cyst aka syrinx expands over time, destroying a portion of the spinal cord from its center and expanding outward.
How do you treat a tear or injury to the extensor reticulum in the wrist?
depends: extend of injury acute / chronic, age of injury, and age of person if this is an acute tear without subluxation or bowstringing of the tendons then you can treat with a splint - wrist will be in neutral position if it's subluxing or bowstringing with extention of the wrist then you can try a splint and if no better then surgically suture the tear and splint. if this goes untreated then you can lose range of motion hope this helps
Which spinal cord structure contains the axons of cns motor neurons that control muscle and glands?
ventral root
Is the spinal cord posterior to the lungs?
No, the heart is anterior to the spine. Posterior means "behind" therefore the spine is posterior to the heart.
One of the soft, cushiony discs that separates each bone in your backbone from its neighbor has begun to bulge and put pressure on two of the nerves branching out from the spinal cord.
What tissue makes up the brain and spinal cord?
The spinal cord and the brain make up part of the nervous system called the central nervous system. The rest of the system is made up of the peripheral nervous system.
How many skateboard injuries cause spinal cord damage?
10,000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
Myoplasia is actually spelled "myeloplasia." It is a defect that causes abnormal development of the spinal cord. Myeloplasia can be toxin-inducing.
What part of the spinal cord acts as the center for simple reflex activity?
The gray matter is the center for simple reflex activity.
- Reflexes are rapid, automatic responses to stimuli that "buy time" for the planning and execution of more complex responses that are often consciously directed.
- The fastest reflexes are somatic motor reflexes that (1) involve myelinated axons, (2) involve only one segment of the spinal cord or one nucleus of the brain, and (3) are monosynaptic.
Orthopedic spinal surgeon salary?
Orthopedic Spine Surgeons have a low of $398,000 and a high of $1,352,000 with a middle figure of $670,000
*edit* actually, the above numbers are off a bit. The median salary for an orthopedic surgeon is in the $400,000 per year range, with the high end in the low to mid $700,000.
The salary depends a great deal on level of experience and location.
Is a woman's spinal cord longer than a man's?
Answer
Sorry your question is like "How long is a rope?"
Answer
The length of the spinal cord is related to the person's height, and the relative length of his or her trunk, which varies. Since men are generally taller than women, most men probably have a longer spinal cord than most women.
Answer
Actually, men's spinal cords are longer than womens. Mens is 45 cm and the woman's is 43 cm.
Ideally you would have a team of three to do a proper logroll. If you do, follow these steps:
- One person holds the casualty's head between their hands, with their left hand on the right side of the head and their right hand on the left. This allows them to keep steady control of the head during the roll. Once this person takes hold of the head, they must keep the head absolutely still with regard to spinal cord movement and they CANNOT let go until the logroll is complete (although it is strongly recommended that the head-holder never lets go until the casualty is fully backboarded, in a tactical situation this may not be possible)
- The other two people get on the same side of the person (coordinate with the head-holder as to which side so that they know how to cross their arms in step 1) - you will be rolling the person towards you so make sure you have space
- Raise the casualty's arm closest to you (the two rollers) so that it is fully extended above their head (as though the casualty were raising their hand high to ask a question)
- The roller closest to the casualty's head places one hand on the casaulty's far shoulder and one hand on the far hip
- The second roller places one hand just above the casualty's far hip and their other hand on the casualty's far knee
- The person holding the head will count to three aloud. On three, the two rollers will slowly and smoothly roll the casualty's back towards them - (pulling their arms inwards) IN COORDINATION WITH the head-holder - until the casualty is fully on their back
I strongly suggest you get hands-on training for this before attempting it.
What is the difference in a lumbar puncture and a spinal tap?
It's the same. Two terms used for one procedure. Or we may say that lumbar puncture is a spinal tap that is done in lumbar area, while spinal tap can also be performed right below the occipital bone (called suboccipital puncture). All in all it's a procedure to obtain the fluid that surrounds the brain and spinal cord.
Do involuntary responses include the spinal cord and not the brain?
No, the brain reads all signals and controls the entire body. The spinal cord is just a "path" for the neurons to take to get to the brain.
