corticospinal tracts are the tracts of the upper motor neurons which originate in the cortex,(precentral gyrus). They terminate in the spinal cord by synapsing with the lower motor neurons either directly or through an interneuron.
lesion to the corticospinal tract results in
Spastic paralysis on the opp side if the lesion is above pyramidal decussation or before crossing over.
Positive Babinski's sign
loss of fine coordination in the distal limbs such as piano playing or typing

What is the main difference between the vertebral foramen and the intervertebral foramen in the spinal column?
The main difference between the vertebral foramen and the intervertebral foramen in the spinal column is that the vertebral foramen is a single opening within each vertebra that allows the spinal cord to pass through, while the intervertebral foramen are openings located between adjacent vertebrae that allow spinal nerves to exit the spinal cord and travel to the rest of the body.
What is the difference between the vertebral canal and foramen in the spinal column?
The vertebral canal is the hollow space within the spinal column that houses the spinal cord, while the foramen are openings in the vertebrae through which nerves pass.
What is the section that demonstrates the continuity between the spinal and cranial cavities?
A midsaggital plane will show the continuity between the spinal and cranial cavities.
What do Disc provide what to the spinal column?
Discs provide cushioning between the vertebrae in the spinal column, allowing for flexibility and shock absorption in the spine. They also help maintain the space between the vertebrae, which is important for preventing nerve compression and maintaining spinal alignment.
Cavity surrounded by the backbones is?
The cavity surrounded by the backbones is called the spinal canal. It houses and protects the spinal cord, which is a bundle of nerves that transmit signals between the brain and the rest of the body. The spinal canal is formed by the vertebral foramen of the stacked vertebrae.
What are the descending fibres of projection fibres?
They include = cortico-spinal fibres + cortico-bulbar fibres + cortico-pontine fibres + cortico-rubral fibres + cortico-striate fibres
What are the descending fibers that can be found in crus cerebri of the midbrain?
in the medial 1/5 = medial corticobulbar + forntopontine fibresin the intermediate 3/5 = cortiocspinal fibresin the lateral 1/5 = temporo-pontine + lateral corticobulbar fibres
Is lumbar spinal stenosis less severe than cervical spinal stenosis?
The difference between lumbar spinal stenosis and cervical spinal stenosis is mainly the location of the problem. however, between the two lumbar spinal stenosis is the more severe form of stenosis.
What is the main difference between the vertebral foramen and the intervertebral foramen in the spinal column?
The main difference between the vertebral foramen and the intervertebral foramen in the spinal column is that the vertebral foramen is a single opening within each vertebra that allows the spinal cord to pass through, while the intervertebral foramen are openings located between adjacent vertebrae that allow spinal nerves to exit the spinal cord and travel to the rest of the body.
What is the difference between a horn and a column in the spinal cord?
A horn is the gray matter of the spinal cord, and a column consist of white matter.
What is the difference between spinal vertebrae and spinal column?
Spinal vertebrae are the individual bones that make up the spinal column, which is the entire structure that protects and supports the spinal cord. The spinal column consists of multiple vertebrae stacked on top of each other, forming the backbone.
The difference between the brain and the spinal cord?
brain controls perception,reflexes,emotionsbehavioral sequences,etc. spinal cord helps in transmission of neural inputs between periphery and brain
What is the difference between the vertebral canal and foramen in the spinal column?
The vertebral canal is the hollow space within the spinal column that houses the spinal cord, while the foramen are openings in the vertebrae through which nerves pass.
What is the difference between ascending tracts and descending tracts of the spinal cord?
ascending carry sensory information toward the brain.descending convey motor command to the spinal cord.
Is there a difference between the lengths of the male and female adult spinal cords?
On average a human female is shorter than a human male, so on average the female spinal cord will be shorter than the male spinal cord. However, you can also see individual females who have longer spinal cords (are taller than) individual males.
Difference between cancer cells and cells of the spinal cord?
Spinal cord cells can never reproduce if they're damaged while cancer cells replicate incredibly fast.
Where is the spinal found?
in the spinal canal between the vertebrae.
