The Brain Flashcards

All 6 cards in this deck

What is the function of the cerebellum?: Coordinates muscle movement and balance (fine movement).
What is the function of the medulla oblongata?: Controls unconscious (involuntary) activities such as heart rate and breathing rate.
What is the function of the cerebral hemispheres?: Control conscious thought, memory, language and intelligence.
True or false? The medulla oblongata controls balance and coordinated movement.: False. The cerebellum does that; the medulla oblongata controls unconscious activities such as heart rate.
Why is a brain tumour difficult to treat?: The brain is encased in the skull so it is hard to reach, and surgery or radiotherapy can damage surrounding healthy brain tissue.
Why can damage caused by a spinal injury usually not be repaired?: Neurones of the central nervous system do not repair or regenerate, so the loss of function (e.g. paralysis) is permanent.
