What extends from the brain and spinal cord to the different parts of the body?

• blood

• nerves

• vertebra

The middle layer supplies the brain with nutrients and oxygen as well as cushions it from shock. The inner layer acts as a wall that prevents bacteria from reaching the brain. The brain and spinal cord are also surrounded by cerebrospinal fluid that cushions the brain and spinal cord against shock from jumping, walking, running, and other movements.
