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.
What are the two main structures that protect the brain?
The brain and spinal cord are protected by bony structures — the skull and spinal column. Meninges are membranes that cover and protect the brain and spinal cord.
What 3 things protect the brain?
Protecting the brain
There are 3 layers of tissue called meninges that help protect the brain. The outer covering of tissue (called the dura mater), closely lines the inside of the skull. The second layer is the arachnoid mater, and the third layer, the pia mater, hugs the surface of the brain.
What are the two main things that protect the brain from physical damage quizlet?
The brain is encased within the cranial cavity of the skull, formed by the securely interlocked cranial bones. The spinal cord is located within the vertebral canal of the vertebral column. The surrounding skull and vertebral column provide a strong, protective shelter against damaging blows or bumps.
What three things protect the brain and spinal cord?
Three layers of membranes known as meninges protect the brain and spinal cord. The delicate inner layer is the pia mater. The middle layer is the arachnoid, a web-like structure filled with fluid that cushions the brain. The tough outer layer is called the dura mater.
What part of brain controls what?
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.
Why is it important to protect the brain?
Brain health is about keeping your mind active, feeding it plenty of nutrients and oxygen, and reducing risk factors that can harm the brain. Chronic conditions that affect our overall physical health – like diabetes, heart disease or high blood pressure, can affect our brain health.
How is the brain protected from damage?
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.
Which structure in the brain maintains the balance in humans?
The brain’s movement control centre
The cerebellum is a small part of the brain positioned at the back of the head, where it meets the spine, which acts as the body’s movement and balance control centre.
