Sad news came from the Indonesian entertainment industry. The news of the death of one of the celebrities, Laura Anna at the age of 21, is still a topic that is still discussed in public, mom.
Before, Laura Anna known to have had an accident and a spinal cord injury two years ago or also known as Spinal cord injury.
Before you learn more about spinal cord injuries, it would be good if Bunda understood the nerve pathways in the spinal cord first.
Nerve tracts in the spinal cord
The chairman of the DKI Jakarta Neurosurgery Specialist Association, Dr. Wawan Mulyawan, stated that the nervous system of the nervous system carries information in the form of electrical nerve impulses to and from the entire body in order to regulate all activities of the human body.
“The basic unit of the nervous system is a nerve cell or neuron, which consists of a cell body, axons and dendrites. In addition to the brain, the spinal cord is the most important part of the nervous system’s network called the central nervous system. “System or CNS,” Wawan explained.
In addition to the CNS, there is another nervous system called the peripheral nervous system that is outside of the CNS nerve in the brain and spinal cord.
In addition, Wawan explained that there are two main systems that can carry information from the brain to the body and vice versa through the spinal cord.
- Outbound or efferent pathways that send commands from the brain to the body to control movement or motor muscles, and autonomic pathways that are responsible for controlling the heart, intestines, and other organs.
- Incoming or afferent pathways that carry information from the outside through the skin, muscles, and other organs to the brain or sensory organs.
“This is all in the spinal cord, made up of more than 20 million axons arranged in spinal tracts or pathways that go in and out of the brain,” Wawan said.
Wawan stated in his written statement that the spinal cord consists of several segments, namely the neck segment (around the neck, arms and hands), the total segment (around the chest area), the lumbar segment (around the hips and legs). Area) and the sacral segment (around the pelvic area, toes, and some parts of the foot).
“They look anatomically, although they look small, from each segment and are connected to specific areas of the body,” said Wawan.
Spinal cord injury (Spinal cord injury)
As defined by the PERDOSSI Association in 2006, a spinal cord injury is a direct or indirect injury to the spine that can result in permanent disability or death.
Two types of damage result from a spinal cord injury:
1.Direct damage from impact or compression (primary)
Injuries to the spinal cord usually occur as a result of trauma to the spine from the neck area to the sacrum. A broken or broken bone puts pressure on the spinal cord or even tears it.
A spinal cord injury can occur without a clear spinal fracture, and conversely, a person can experience a spinal fracture without a spinal cord injury.
However, most spinal cord injuries compress or tear the spinal cord. The severity of the nerve damage depends on the strength of the compression of the nerve by the spinal cord, the strength of the force acting and the duration of the compression or the rescue time.
2. Additional damage (secondary)
Secondary damage can result from ongoing primary damage, from inadequate or improper assistance, so that the damage, which should be lighter, becomes more severe or becomes permanent.
“If immediate treatment is not given after an accident or injury, it will lead to inadequate supply of nutrients and oxygen to nerve cells and ultimately to permanent death,” said Wawan.
When the nerve cells in the marrow bone Injured spinal cord, axon, or astrocyte injuries are not treated quickly and appropriately and can even self-destruct from the production of toxic chemicals or free radicals.
