The blood-brain barrier prevents various substances that could be poisonous to brain tissue (toxins), as well as many agents of infection, from crossing from the blood stream into the brain tissue.

skull your brain to be protected.
There are three things that protect the CNS; brain and spinal cord. Bone which is the skull for the brain and the vertebrae for the spinal cord, meninges which is a protective membrane, and the spaces between the meninges are filled with cerebrospinal fluid for cushion and protection.
Netilmicin does not cross the blood-brain barrier.
thebone membraneprotects the brain by using the blood brain barrier filters and other materials.cerebrospinal fluid containing the detoxification chemicals that helps to protect the brain.The brain is protected by the skull (a bone structure), the blood brain barrier (BBB) filters the passage of harmful substances other other foreign materials,cerebrospinal fluid contains detoxification chemicals and helps cushion the brain, and there are 3 membranes that protect the brain called dura, arachnoid and pia mater.
Insulin does crosses the blood brain barrier. Insulin crosses the blood brain barrier through the process of receptor-mediated transcytosis.
Inflammation may cause the blood-brain barrier to become less effective at preventing the passage of toxic substances into brain tissue.
The blood-brain barrier is effective against the passage of ? Metabolic waste such as urea
The blood brain barrier is inhibited in case of inflamed meninges. Probably the injection of histamine may release the blood brain barrier. The expert comment is awaited in this regard.
The blood brain barrier (BBB) is composed of a high concentration of endothelial cells in the brain's capillaries, which help to prevent toxins from passing into the brain from the blood supply.
