| Question | Answer |
|---|---|
| Branch of the nervous system that contains theh sympathetic and parasympathetic nervous systems | autonomic nervous system |
| waterty, clear fluid that surrounds the brain and spinal cord | cerebrospinal fluid |
| section of brain located below the cerebrum at the top of the brainstem | midbrain |
| regulates and controls autonomic nervous system, temperature, appetite, water balance, sleep and blood vessel constriction and dilation | hypothalamus |
| mass of nerve tissue well protected by membranes and the cranium | brain |
| division of the peripheral nervous system which carries messages between the central nervous system and the body | somatic nervous system |
| the largest and highest section of the brain | cerebrum |
| consists of nerves and has 2 divisions, the somatic nervous system and the autonomic nervous system | peripheral nervous system |
| section of brain responsible for muscle coordination, balance, posture, and muscle tone | cerebellum |
| structure within the diencephalon that act as a relay center and directs sensory impulses to the cerebrum | thalamus |
| consists of the brain and spinal cord | central nervous system |
| section of the brain located between the cerebrum and midbrain, contains 2 structures; the thalamus and hypothalamus | diencephalon |
| lowest part of the brainstem, it connects with the spinal cord and is responsible for regulating heartbeat, respiration, swallowing, coughing, and blood pressure | medulla oblongata |
| combination of many nerve fibers located outside the brain and spinal cord | nerves |
| complex highly organized system that coordinates all the activities of the body | nervous system |
| division of the autonomic nervous system, works after an emergency to decrease heart rate, respiration, blood pressure, and increasing activity in the digestive tract | parasympathetic system |
| four hollow spaces within the brain that contain clear, colorless fluid called cerebrospinal fluid | ventricles |
| section of brain located below the midbrain and in the brainstem, responsible for conducting messages to other parts of the brain, certain reflexes including chewing, tasting, and saliva production | pons |
| 3 membranes that cover and protect the brain and spinal cord | meninges |
| basic structural unit of the nervous system | neuron |
| continues down from the medulla oblongata and ends at the first or second lumbar vertebrae | spinal cord |
| one of the two divisions of the autonomic nervous system; in times of emergency it increases heartrate, blood pressure, respirations, and slows activity in the digestive tract | sympathetic nervous system |
| acute inflammation of nerve cells and is caused by the herpes virus | shingles |
| disturbance in voluntary muscle action and is caused by brain damage | cerebral palsy |
| chronic progressive disabling condition resulting from degeneration of the myelin sheath in the CNS | muliple sclerosis |
| inflammation of the brain, caused by a virus that is frequently contracted from a mosquito bite | encephalitis |
| occurs when blood flow to the brain is impaired, resulting in lack of oxygen and a destruction of brain tissue | cerebrovascular accident (CVA)(stroke) |
| excessive accumulation of cerebrospinal fluid in the ventricles | hydrocephalus |
| results from a brain or spinal cord injury that destroys neurons and results in a loss of function and sensation below the level of the injury | paralysis |
| brain disorder associated with abnormal electrical impulses in the neurons of the brain | epilepsy |
| inflammation of the meninges of the brain and/or the spinal cord | meningitis |
| chronic, progressive condition involving degeneration of brain cells | parkinson's disease |
| What are the two types of spinal nerves | afferent and efferent |
| milder seizures that are characterized by a loss of consciousness lasting only a few seconds | petit mal or absence seizures |
| most severe seizures that are characterized by a loss of consciousness lasting several minutes; convulsions accoumpanied by violent shaking and thrashing movements | grand mal seizures |
| paralysis of the arms, legs, and body below the spinal cord injury | quadriplegia |
| symptoms of this disease include tremors, stiffness, muscular rigidity, a shuffling gait, and a loss of facial expression | parkinson's disease |
| paralysis of the lower half of the body or lower extremities | paraplegia |
| drug that helps prevent injury to neurons are called_____ | neuroprotective agents |
| the part of the brain responsible for conducting impulses between brain parts and for certain eye reflexes is the ______ | midbrain |
| A ________________________ accident commonly causes quadriplegia, hemiplegia, or paraplegia | cerebrovascular (accident) |
