Aromatherapy: Essential Oils For Brain Function! Trivia Quiz

Explanation
The cerebro-spinal fluid plays a crucial role in protecting the brain from infections by containing cells that act against infection. These cells help to prevent the entry and spread of harmful pathogens in the brain. Additionally, the cerebro-spinal fluid supplies essential nutrients to the brain and spinal cord, ensuring their proper functioning and maintenance. However, it does not generate motor impulses to the muscles, which is not a function of the cerebro-spinal fluid.

Explanation
The brachial plexus is a network of nerves that originates from the spinal cord in the neck and supplies the upper limb. The radial nerve, axillary nerve, and median nerve are all branches of the brachial plexus and play a crucial role in innervating different muscles and providing sensory information to the upper limb. Therefore, these three nerves are correct answers as they are part of the brachial plexus and supply the upper limb.

Explanation
The Autonomic Nervous System is indeed a part of the nervous system that operates without conscious control. It receives instructions from the brain and controls various involuntary bodily functions such as heart rate, digestion, and breathing. This system works automatically to maintain homeostasis in the body, ensuring that essential processes continue to function properly without us having to consciously think about them. Therefore, the statement "The Autonomic Nervous System is part of the nervous system which receives instructions from the brain, usually not under conscious control" is true.

Explanation
The given statement is incorrect. The functions of the left hemisphere of the brain are primarily related to logical thinking, language processing, and analytical tasks. It is considered to be the dominant hemisphere for most individuals. On the other hand, the right hemisphere is associated with creativity, intuition, spatial awareness, and holistic thinking. Both hemispheres work together and are involved in various cognitive processes, but they have different specialization and functions. Therefore, the correct answer is False.

Explanation
The statement is false because the cerebrum is not covered by two layers of meninges. The cerebrum is indeed the largest part of the brain and fills most of the skull, but it is covered by three layers of meninges: the dura mater, arachnoid mater, and pia mater.

Explanation
The cerebellum, which is divided by the Pons Varolii, is responsible for coordinating muscle movement, maintaining balance, and regulating muscle tone and alertness.
