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.

Where is the best place for spinal cord injury?
There are no "best" places for spinal cord injury. Any injury to the spine has negative results. The most severe injuries and more common ones occur within the lower spinal columns.
How many spinal cord injuries happen a year?
According to The University of Alabama's National Spinal Cord Injury Statistical Center (NSCISC), which compiles the data, approximately 11,000 spinal cord injuries (SCIs) occur each year
What are facts about the spinal cord?
Some facts about the spinal cord:
- It is easy to break
- the spinal cord is a part of the nervous system
- it sends messages to the brain
What is the main disadvantage of Luque rods?
The main disadvantage is that the risk of injury to the nerves and spinal cord is higher than with a some other forms of instrumentation. This is because wires must be threaded through each vertebra near the spinal column.
Do vocal cords produce high pitch?
it is totally dependent on who is speaking and who is the person he is talking to
How much does spinal fluid donation pay?
Legally you can only donate 50ml of your 120ml - 150ml amount. Prices vary from £100 per ml to £200 per ml. Even though the body regenerates the fluid, it does not create more fluid once it's gone.
How does damage to the spinal cord affect your mental processes and behavior?
Spinal injury does not affect mental processing at all. This is save for the psychological effects of having to come to terms with the disability. It would also not affect the base personality of the injured person - the behviour of the injured person would remain the same - depending on the mobility requirement of the behaviour you are referring to - as well as the psychological acceptance level of the individual.
What part of nervous system carry all spinal nerves?
The nervous system consists of the brain, spinal cord, and a complex network of neurons. This system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. This system can be divided into two parts: the central nervous system and the peripheral nervous system. Let's take a look at the peripheral nervous system.
Peripheral Nervous SystemThere are two types of cells in the peripheral nervous system. These cells carry information to (sensory nervous cells) and from (motor nervous cells) the central nervous system (CNS). Cells of the sensory nervous system send information to the CNS from internal organs or from external stimuli.Motor nervous system cells carry information from the CNS to organs, muscles, and glands. The motor nervous system is divided into the somatic nervous system and the autonomic nervous system. The somatic nervous system controls skeletal muscle as well as external sensory organs such as the skin. This system is said to be voluntary because the responses can be controlled consciously. Reflex reactions of skeletal muscle however are an exception. These are involuntary reactions to external stimuli.
The autonomic nervous system controls involuntary muscles, such as smooth and cardiac muscle. This system is also called the involuntary nervous system. The autonomic nervous system can further be divided into the parasympathetic and sympathetic divisions.
The parasympathetic division controls various functions which include inhibiting heart rate, constricting pupils, and contracting the bladder. The nerves of the sympathetic division often have an opposite effect when they are located within the same organs as parasympathetic nerves. Nerves of the sympathetic division speed up heart rate, dilate pupils, and relax the bladder. The sympathetic system is also involved in the flight or fight response. This is a response to potential danger that results in accelerated heart rate and an increase in metabolic rate.
Thats all I know about a nervous system and spinal nerves hope it is helpful.
What part of the brain connects the spinal cord and various parts of the brain called?
medula oblongata
Why does a crush fracture of a thoracic vertebra rarely result in damage to the spinal cord?
In a crush fracture, the vertebral body collapses. This may not cause displacement of intervertebral (IV) discs or any of the verebral components. Thus, the spinal cord is unlikely to get injured. Crush fracture of the body indicates collapse, and so long the vertebral arch and IV discs are not dirupted the spinal canal will not be compromised. But that may also be applicable to all regions. The thoracic region however as it is convex posteriorly, collapse of the vertebral body will simply increase the convexity.
What could an M-and-M sized lump be on the lower spine that periodically gets very sore?
It could be many things ... slipped disc, disintigrating disc or a bone spur. I would suggest you get go to the doctors and get an x-ray done. If it's a slipped disc you can see a Chiropractor. A lump like that at the top of the crease of the buttocks could be a pilonidal cyst. It can be very painful, but a doctor can lance and drain it.
Describe the protective structures and the gross anatomical features of the spinal cord?
two types of connective tissue coverings - bony vertebrae and tough, connective tissue meninges - plus a cushion of cerebrospinal fluid surround and protect the delicate nervous tissue of the spinal cord.
What neurotransmitters enhance pain messages at the injury site at in the spinal cord?
Certain neurotransmitters, especially substance P and calcitonin gene-related peptide, actively enhance the pain message at the injury site and within the spinal cord.
What is the ambilicol cord connected to?
The correct spelling is umbilical, and this cord is attached to the baby's navel when it is born. The baby receives nutrients through this cord prior to the time the physician cuts it.
What is one responsibility of the spinal cord?
To send messages to the different nerves throughout the human body via the spinal cord so that the body can move (for example a person walking).

Essentially, when a spinal tap is given, a needle is inserted into the spinal canal in the lumbar area, medicine (or an anesthetic) is inserted directly into the cerebrospinal fluid (CSF). Numbness is usually immediate.
However, in an epidural, a hollow needle and a catheder are inserted into space between the spinal column and the outer membrane of the spinal cord (EPIDURAL space). Hence the name "epidural".
There are a lot of folks walking around with a c-spine herniated nucleus pulposis (HNP) and don't know it until for some reason an MRI is ordered...!!
What would tell me to refer you to my boss (a neurosurgeon) would be an MRI that demosntrated moderate-severe compression of the spinal cord, that you have symptoms of upper extremety wasting/weakness of the muscles, inability to work with your arms above your head for any length of time AND abnormal nerve conduction studies (NCV's & EMG's) of the upper extremeties. A neurologist often could be the referring physician as well...
The key is an advanced degree of spinal cord compression AND those symptoms I mentioned above...
A neurosurgeon is the final authority as to whether you need surgery --or not...
