1. Is the ability of cerebral blood vessels to change in diameter in response to arterial pressure changes. This ability controls the blood volume occupying the brain, ensuring there is enough to sustain cellular function and restricting too much volume from entering the confined cranial cavity
2. Also known as a nerve cell, is the basic functional unit of the nervous system and serves as the transmitter of nerve impulses
3. Are star-shaped cells that play a critical role in transport of nutrients, gases, and waste products among neurons, the vascular system, and cerebrospinal fluid (CSF); in the formation of scar tissue in the brain; and in the function of the blood-brain
4. Constitute the supportive tissue of the CNS
5. This circle is formed by the anterior communicating artery, which joins together the two anterior cerebral arteries, and the posterior communicating arteries, which arise from the internal carotid arteries and connect to the posterior cerebral arteries
6. Is a deficit in language output or speech production from a dysfunction in the dominant frontal lobe
7. Is the inability to comprehend language and follow commands is called receptive dysphasia
8. A colorless liquid that is comparable to serum, is secreted from the blood into the lateral ventricles of the brain, and serves chiefly to maintain uniform pressure within the brain and spinal cord
9. To protrude through an abnormal body opening
10. Collection of blood in the subdural space
11. Sudden impairment or loss of consciousness, sensation, and voluntary motion that is caused by rupture or obstruction (as by a clot) of a blood vessel supplying the brain, and is accompanied by permanent damage of brain tissue
12. A stroke caused by the narrowing or blockage of a blood vessel supplying the brain
13. A stroke caused by the rupture of a blood vessel in or on the surface of the brain with bleeding into the surrounding tissue
14. Situated or occurring within or introduced or administered into the cerebrum
15. Congenital abnormality forming an abnormal communication between arterial and venous systems in the brain
16. An abnormal blood-filled bulge of a blood vessel and especially an artery resulting from weakening (as from disease) of the vessel wall
17. The physical manifestations (such as convulsions, sensory disturbances, or loss of consciousness) resulting from abnormal electrical discharges in the brain (as in epilepsy)
18. A disease marked by inflammation of the meninges that is either a relatively mild illness caused by a virus (such as various Coxsackieviruses) or a more severe usually life-threatening illness caused by a bacterium (especially the meningococcus, Neisseria meningitides, or the serotype designated B of Haemophilus influenzae
19. A temporary condition following transection of the spinal cord that is characterized by muscular flaccidity and loss of motor reflexes in all parts of the body below the point of transection
20. A disorder of spinal reflex activity occurring in those with spinal cord injury that is characterized by a sudden onset of hypertension, bradycardia, excessive sweating, and headache
