Explanation:
11. The occipital lobe is found at the lower back of the brain. This is the smallest lobe, and it is also known as the visual center of the brain because it helps us process or interpret what we see with our eyes.
12. The frontal lobe is found, as the name suggests, in the front portion of the brain. It controls higher order of thinking skills (this means cognitive skills) like problem solving, decision making, and the like.
13. The pituitary gland is also known as the master gland. It is deemed so because it controls other glands in the endocrine system. It is about the size of a pea and it is found between the the hypothalamus and pineal gland.
14. Technically, the frontal lobe is responsible for language, speaking and memory. However, the frontal lobe, along with the other 3 lobes of the brain is part of the Cerebrum. It is the largest part of the brain.
15. The medulla oblongata is part of the hindbrain, specifically located on the brainstem. It is the lower half of the stem that connects to the spinal cord. It controls functions of the autonomic nervous system like breathing, heart rate, and the like.
16. Stroke happens when the blood supply to the brain is impeded or is insufficient. This deprives the brain of oxygen and the cells in the affected part of the brain then die.
17. Alzheimer's disease is a degenerative disease. It is called degenerative because it is progressive, The brain cells in the cerebrum start to deteriorate and affects the functions that the cerebrum controls. Â
18. Encephalitis is the inflammation of the brain. It can be caused by many things but infection is usually the cause, particularly viral infections. There are two types of encephalitis: primary encephalitis, which happens when the infection is in the brain itself; and secondary encephalitis, which happens when the infection occurs somewhere else other than the brain.
19. Concussion is a type of trauma to the brain. It usually occurs after a blow to the head that causes your brain to shake inside your skull. A concussion can lead to an altered mental state or even unconsciousness.
20. Brain tumor is the abnormal growth of tissue in the brain. Actually, any abnormal growth of cells is a tumor. Â Brain tumors can grow on the brain or can also occur as a result of another tumor growing in another part of the body and it metastasizes (spreads) to the brain.
