Reflexes don't go up the spinal cord to the brain, as the body wants to remove itself from the stimulus as quickly as possible. So, it goes in a loop, called a reflex arc, where the sensory neurons detect the tap and the stimulus is so strong it immediately jumps to the motor neurons to make the leg jerk. It all happens in the spinal cord.
However, you don't feel it because the nerves going up (afferent) and down (efferent) the spinal cord to the brain have been severed and so the brain doesn't detect it.
Where does CFS produced deep inside the brain flow to?
CSF, produced within specialized chambers deep inside the brain, flows over the surface of the brain and spinal cord.
What bones that protects your spinal cord are called?
They are called the vertebrae, and are divided into six different classes depending upon which part of the spine they consist of. The topmost ones are the cervical vertebrae, and the bottom-most ones the coxxygial vertebrae. The largest category are the lumbar vertebrae, which makes up at least a third of the spine as a whole.
It refers to the underside of something, usually a fish. Also refers to the belly area.
What does the structure of the mammalian brain indicate about intelligence?
Mammalian intelligence depends mostly on the folds present in the cortex. The more folded the cortex the smarter. If you compare a rat brain to a human brain, the rats brain will be alot smoother and flatter.
Describe the organization and distribution of spinal nerves?
In the human there are 31 pairs of spinal nerves, one on each side of the vertebral column. ... The posterior distribution includes the suboccipital nerve (C1 ), the greater ..... trademark of the Wikimedia Foundation, Inc., a non-profit organization.
Sympathetic nerves may leave the spinal cord at which vertebra?
Preganglionic sympathetic axons leave the spinal cord throughout the thoracic spine and the upper lumber spine (T1-L2).
These preganglionic sympathetic axons exit the spinal canal within the anterior primary ramus and then quickly separate to travel via the white ramus communicans to the ipsilateral sympathetic trunk.
Why did God create the spinal cord to be the main pathway of the nervous system?
Ask God first because I don't think humans have any ideas...
The spinal cords job is to send messages from parts of the body to the brain and vice versa. Did you know that if your spine is out of alignment the messages may not get through properly and can actually cause symptoms in your body that don't relate to your orignial issues. Some people don't believe in alternative medicine but having your spine aligned by a ligitimate Chiropractor can put your body at it's optimum health and allow it to heal itself...rather then popping pills that just cover your symptoms up, you may consider a trip to your local Chiropractor. I only speak from experience...
What kind of nerves are in the upward tract and downward tract of the spinal cord?
The ascending tracts (upward) contain sensory nerves, that pass sensory information from the body to the brain.
The descending tracts (downward) contain motor nerves that activate the muscles in the body according to the brain's "commands".
What is the tapering of the cord called?
The tapering of the spinal cord is known as the conus medullaris. It is the terminal end of the spinal cord, which typically occurs around the level of the first or second lumbar vertebra in adults. Below the conus medullaris, the spinal nerves continue as a collection known as the cauda equina. This structure is crucial for the proper functioning of the lower body and pelvic organs.

How long does a spinal cord tear take to heal once blood has been injected into the spinal cord?
It is not certain that full recovery can be made after a spinal cord injury, but stem cell injection therapies have been shown to help in some cases. It can take over 6 months for this therapy to show results.
In the case of a blood patch after spinal tap or epidural, the "leak" usually heals itself within a day or two.
If you can have it removed! I myself had a benign spinal cord tumor removed 9 months ago and still am recovering from it. The spinal cord tumor may likely just keep growing in size and cause more compressison on the spinal cord. This compression can lead to many bad symptoms and ultimately paralysis (in my case it would of at least).
A dorsol hollow nerve cord is a major phylum in the Kingdom Animalia. A chordate is characterized by the presence of a dorsal notochord at some stage of development.
An agal is a cord fastened around a kaffiyeh, a form of cloth worn around the head and neck by some Arabs.
