The spinal cord is an essential part of the human body as it helps in controlling various functions such as body movement, sensation, and the ability to perform various actions. To ensure that the spinal cord functions efficiently, it requires protection from various factors that can cause damage to it. In this article, we explore what protects the spinal cord.
The Protective Structures of the Spinal Cord
The spinal cord is protected by various structures that help to cushion it and prevent damage from external factors. The structures that protect the spinal cord include:
The vertebral column is made up of 33 individual bones known as vertebrae that are stacked on top of one another. The vertebrae help to protect the spinal cord from external injuries by surrounding it. Each vertebra is separated from the adjacent vertebrae by intervertebral discs that act as shock absorbers.
The meninges are a series of three membranes that surround the brain and spinal cord. They provide cushioning and support to the spinal cord while also helping to protect it from any external pressure. The three meninges are:
- Dura Mater: This is the outermost covering of the meninges and is a thick, tough membrane that provides protection to the spinal cord.
- Arachnoid Mater: This is the middle covering of the meninges and is a delicate layer that helps to cushion the spinal cord.
- Pia Mater: This is a thin membrane that is located closest to the spinal cord and helps to nourish and protect it.
The cerebrospinal fluid is a clear, colorless liquid that circulates around the brain and spinal cord. It acts as a cushioning agent, helping to protect the spinal cord from any impact or shock.
Common Causes of Spinal Cord Injuries
Besides understanding the structures that protect the spinal cord, it is also essential to know of some common causes of spinal cord injuries. The following are some of the most common causes of spinal cord injuries:
One of the most common causes of spinal cord injuries is trauma. This can occur from a sudden accident or fall that causes a fracture or dislocation in the vertebrae. The impact can cause damage to the spinal cord and result in injury.
Several diseases can lead to spinal cord injuries, including multiple sclerosis, spinal tumors, and polio. These conditions can cause damage to the spinal cord that results in the inability to control body movements.
Infections of the spinal cord such as meningitis, syphilis, and tuberculosis can cause inflammation that can lead to spinal cord injuries.
The spinal cord can also be injured due to compression caused by conditions such as herniated discs or bone spurs.
Preventing Spinal Cord Injuries
While it may not be possible to protect the spinal cord entirely from injury, there are some preventive measures that one can take to reduce the risk. The following are some of the ways to prevent spinal cord injuries:
Wear a Seat Belt
Wearing a seatbelt while driving or riding in a car can prevent spinal cord injuries in the event of an accident. Seat belts help to keep the body restrained, reducing the risk of injury.
Practice Safe Sport
Wearing appropriate protective gear while engaging in high-risk sports such as football or baseball can reduce the risk of spinal cord injuries. Helmets, knee pads, and elbow pads are essential in preventing spinal cord injuries.
Avoid Diving into Shallow Waters
The risk of spinal cord injury increases when diving into shallow waters. Before diving, it is essential to check the water depth and make sure it is deep enough to avoid injury.
The spinal cord is an essential part of the human body that requires protection from various external factors that can cause injury. Understanding the structures that protect it and the common causes of spinal cord injuries can help to reduce the risk of injury.
