1. The Skull: The skull is the primary protective structure for the brain, providing both a hard, outer shell as well as cushioning within the cranium.
2. Meninges : The meninges are layers of tissue that surround and protect the brain and spinal cord.
3. Cerebrospinal Fluid: The cerebrospinal fluid is a clear, colourless liquid that cushions and protects the brain and spinal cord from impact and injury.
4. Blood-Brain Barrier: The blood-brain barrier is a protective barrier of cells that line the blood vessels within the brain and prevent certain substances from entering the brain tissue.
5. Protective Reflexes: Protective reflexes are built-in reactions that occur when the body senses a threat to the head, such as a sudden jerk of the neck, tensing of the neck muscles, and closing of the eyes.
