The brain is housed inside the bony covering called the cranium. The cranium protects the brain from injury. Together, the cranium and bones that protect the face are called the skull. Between the skull and brain is the meninges, which consist of three layers of tissue that cover and protect the brain and spinal cord.
What are the protection of the brain?
The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. The brain is also cushioned and protected by cerebrospinal fluid. This watery fluid is produced by special cells in the four hollow spaces in the brain, called ventricles.
Where is the brain least protected?
Non-Protected Areas of the Brain
Several areas of the human brain are not protected by the BBB. These include the circumventricular organs such as the area postrema, median eminence of the hypothalamus, pineal gland, and the posterior pituitary.
Why does your skull not protect your brain?
The brain probably moves very little inside the skull — there are only a few millimeters of space in the cranial vault — and it’s filled with cerebrospinal fluid, which acts as a protective layer.
What is between the brain and skull?
Between the skull and brain is the meninges, which consist of three layers of tissue that cover and protect the brain and spinal cord. From the outermost layer inward they are: the dura mater, arachnoid and pia mater. … Arachnoid: The second layer of the meninges is the arachnoid.
