How is your brain protected?

The brain has three main parts: the cerebrum, cerebellum and brainstem. Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.

What 4 Things protect the brain?

The brain is protected by the skull (cranium), cerebrospinal fluid and 3 protective membranes (Meninges). The spinal cord is protected similarly but with vertebrae instead of the cranium.

What is the protective shield around the brain?

Our brains are protected by a shield known as the blood-brain barrier (BBB). It gets its name because, in a healthy brain, components of the blood are excluded from the brain tissue by a barrier made up of different cells and other factors, which creates a division between the circulatory system and the brain.

What are the 3 types of the brain?

The brain can be divided into three basic units: the forebrain, the midbrain, and the hindbrain. The hindbrain includes the upper part of the spinal cord, the brain stem, and a wrinkled ball of tissue called the cerebellum (1).

How is brain protected from injury and shock?

The brain, master organ of the body is protected by the hard bony covering called as skull or cranium and also it has three thin membranes known as meninges. The cerebrospinal fluid (CSF) is present between the meninges and brain which acts as a shock absorber and thus helps in the protection of the brain.

What protects the brain from external injury?
