The cranium protects the brain from injury and along with the 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 three things protect the brain from injury?
The brain and spinal cord are covered by three layers of meninges, or protective coverings: the dura mater, the arachnoid mater, and the pia mater. Cerebrospinal fluid surrounds the brain, cushioning it and providing shock absorption to prevent damage.
How is your brain protected?
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. There are three layers of meninges: Dura mater, which is closest to the bone.
What are the 3 major parts of the brain and their functions?
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 are 3 ways to keep your nervous system healthy?

- Exercise regularly. …
- Do not smoke or use other tobacco products. …
- Get plenty of rest.
- Take care of health conditions that may cause decreased nervous system functioning, such as: …
- Eat a balanced diet.
How can accidents that damage the brain instruct us in its functions?
A traumatic brain injury interferes with the way the brain normally works. When nerve cells in the brain are damaged, they can no longer send information to each other in the normal way. This causes changes in the person’s behavior and abilities.
What are the 3 main regions of the vertebrate brain?
The vertebrate brain is divided into three major divisions, the hindbrain, midbrain, and forebrain.
What are the three major divisions of the brain quizlet?
Terms in this set (3)

- Midbrain. In the middle of the brain and the top of the brainstem. Sensory pathways, visual and auditory processing/reflexes. …
- Forebrain. The most anterior and most promient part of the mammalian brain.
What are the 5 structures that protect the brain?
12.2: Support and Protection of the Brain
- Protective Coverings of the Brain.
- Cranial Meninges. Dura Mater. Arachnoid Mater. Pia Mater.
- Blood Supply to the Brain. Arterial Supply to the Brain. Venous Return from the Brain.
- Ventricular System. Ventricles. Cerebrospinal Fluid Circulation.
What protects the brain from external injury?
The brain is housed inside of a bony covering called the cranium. The cranium protects the brain from injury and along with the bones that protect the face are called the skull.
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.
