Sad news came from the Indonesian entertainment industry. The news of the death of one celebgram, Laura Anna at the age of 21, is still a topic that is still being discussed by the public, Mother. Previously, Laura Anna was known to have had an accident two years ago and suffered a spinal cord injury or also known as a spinal cord injury. Before knowing more about spinal cord injuries, it’s good if you understand the nerve pathways in the spinal cord first. Nervous pathways in the spinal cord The chairman of the DKI Jakarta Neurosurgery Specialist Association, dr Wawan Mulyawan, explained that the nervous system network carries information in the form of electrical nerve impulses to and from the entire body 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. Besides the brain, the spinal cord is the most important part of the network in the nervous system called the central nervous system or CNS,” explained Wawan. Apart from the CNS, there is another nervous system called the peripheral nervous system, which is located outside the nerves in the brain and spinal cord. Furthermore, Wawan explained that there are two main systems that can convey information from the brain to the body and vice versa, through the spinal cord. Outbound or efferent pathways, which send commands from the brain to the body to control movement or motor muscles, and autonomic pathways in charge of controlling the heart, intestines, and other organs. Incoming or afferent pathways, which will transmit information from the outside through the skin, muscles, and other organs to the brain or sensory. “This is all in the spinal cord formed by more than 20 million axons, which are arranged in spinal pathways or tracts that go in and out of the brain,” said Wawan. In his written statement, Wawan explained that the spinal cord consists of several segments, namely the cervical segment (around the neck, arms, and hands), the total segment (around the chest area), the lumbar segment (around the hip and leg 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 certain areas of the body,” said Wawan. Spinal cord injury Based on the definition of the PERDOSSI Association in 2006, spinal cord injury is an injury to the spine, either directly or indirectly, which can cause permanent disability or death. Two types of damage from spinal cord injuries: 1. Direct damage from impact or compression (primary) Injuries to the spinal cord usually result from trauma to the spine, from around the neck to the sacral spine. A fractured or broken bone will put pressure on the spinal cord or even tear it. A spinal cord injury can occur without a clear spinal fracture, and conversely, a person may experience a spinal fracture without a spinal cord injury. However, most spinal cord injuries compress or tear the spinal cord. The severity of nerve damage depends on the strength of the compression of the nerve by the spinal cord, the severity of the impacting force, and the duration of compression or duration of rescue. 2. Additional (secondary) damage Secondary damage can occur due to ongoing primary damage, due to inadequate or inappropriate assistance, so that the damage that should be lighter, becomes more severe or becomes permanent. “If after an accident or injury is not treated immediately, it will lead to insufficient delivery of nutrients and oxygen to nerve cells, and eventually permanent death,” explained Wawan. , it can even self-destruct by producing toxic chemicals or free radicals.
