31.    What is the primary purpose of the blood brain barrier (BBB)? a.    provides the brain with oxygenated bloodb.    provides the brain with glucose & other nutrientsc.    drains venous blood via the internal jugular vein back to the heartd.    is a barrier that protects the brain from toxic substances in the bloode.    causes strokes when blood cannot flow to the brain  

19.    What happens if ONLY the ventral roots of a spinal nerve between C5-T1 are severed? a.    motor control of visceral organs to the thoracic & abdominal cavity would be impairedb.    the spinal cord would not be able to receive any sensory information at that levelc.    the brain would not be able to communicate in any way with spinal cordd.    incoming sensory information to the brachial plexus of the spinal cord would be disruptede.    motor control of skeletal muscles to the brachial plexus would be interrupted  

20. In diagnosing bacterial and viral infections of the brain, samples of cerebrospinal fluid (CSF) are extracted for analysis.  This procedure would withdraw CSF from the?   a. cerebral spinal space between the brain & spinal cord b. epidural space above the dura mater c. subarachnoid space of the brain between the dura mater & arachnoid d. subarachnoid space of the spinal cord between the arachnoid and pia mater e. ventricles of the brain that contain CSF

36.    Damage to the pyramidal cells of the frontal lobe of the cerebral cortex would directly affect? a.    sensory perception of painb.    sightc.    voluntary somatic motor & voluntary skeletal muscle controld.   hearing & olfactione.   taste  

28.    The regulation and control of subconscious  non-vital reflex physiologic functions, such as thirst, appetite, body temperature, sex, fear, and most autonomic functions, originates in the? a.    diencephalons (hypothalamus)b.    spinal cordc.    cerebellumd.    cerebrume.    medulla oblongata  

13. Which statement below, about the spinal cord, is TRUE? a.    there are 8 cervical vertebrae and 7 cervical spinal nerve segmentsb.    there are 7 cervical vertebrae and 8 cervical spinal nerve segmentsc.    there are 26 spinal nerve segments and 31 vertebraed.    there are 7 cervical, 12 thoracic, 5 lumbar, 5 sacral & 1 coccygeal, spinal nerve segmentse.    the vital cranial vegus nerve comes off the spinal cord at spinal nerve segment C-3  

27.    Why would a person who suffers a severe injury to the spinal cord at the level of C-3 or above, lose all sensory and motor function below that level, but still maintain normal heart, liver, kidney, and digestive functions? a.    vital organ function is totally controlled by the spinal cord & cranial reflexesb.    the organs mentioned above are controlled the vagus nerve which comes off below C-3c.    vital organ function is controlled by the phrenic nerve which comes off segment C-3d.    the spinal cord has complete control over those vital organs mentioned abovee.    vital organ function is controlled by the vagus nerve which is a cranial nerve

39.    A tumor that results in violent mood swings, depression, emotion changes and lack of motivation could likely involve the? a.    hypothalamus, pre-frontal cortex & limbic systemb.    medulla oblongatac.    cerebellumd.    ponse.    brain stem

25.    The order of formation of a plexus, beginning with the spinal cord & ending at the nerve, is? a.    spinal cord, roots, rootlets, rami, spinal nerves, trunks, cords, peripheral nervesb.    spinal cord, roots, rootlets, spinal nerves, rami, cords, trunks, peripheral nervesc.    spinal cord, rootlets, roots, spinal nerves, rami, peripheral nerves, trunks, cordsd.    spinal cord, rootlets, roots, spinal nerves, peripheral nerves, trunks, cords, ramie.   spinal cord, rootlets, roots, spinal nerves, rami, trunks, cords, peripheral nerves  

11.    What reflexes are the simplest, most-rapid, and consist of type-A fibers? a.    acquired reflexesb.    innate reflexesc.    polysynaptic or crossed extensor reflexesd.    monosynaptic reflexes or patellar reflexese.    c & d
