| Question | Answer |
|---|---|
| controlled voulntarily(by conscious will), and all its effectors are skeletal muscles | Somatic nervous system |
| in what process does The action potential, K+ channels open to allow K+ to leave the cell. | Repolarization |
| As the electrical charge returns to its resting value, the membrane is undergoing | Repolarization |
| A disease in which the myelin sheath around axons is damaged and the neuron fibers themselves degenerate. | Multiple sclerosis |
| paralysis of all four limbs | tetraplegia |
| CSF forms in four spaces within the brain called | ventricles |
| A vascular network in each ventricle that forms CSF by filtration of the blood and by cellular secretion. | choroid plexus |
| Ventricle extentions inot the lobes of the cerebrum are called | horns |
| These paired ventricles communicate with a midline space, the third ventricle, by means of openings called | interventricular foramina |
| Continuing down from the third ventricle a small canal extends through the midbrain into the fourth ventricle, which is located between the brain stem and the cerebellun | Cerebral aqueduct |
| Occupies the superior part of each hemisphere and lies posterior to the central sulcus. | parietal lobe |
| The gyrus just behind the central sulcus in ths lobe contains the _________ , where impulses from the skin, such as touch, pain, and temperature, are interpreted. | primary sensory area |
| lies posterior to the parietal lobe and extends ovet the cerebellum | occipital lobe |
| The speech muscles in the tongue, the soft palate, and the larynx are controlled her, in a region named the | motor speech area |
| motor speech area is also know as | Broca area |
| What influences the heartbeat, the contraction and relaxation of blood vessels, hormone secretion, and other vital body functions | hypothalamus |
| chronic disorder involving an abnormality of the brain's electrical activity with or without apparent changes in the nervous tissues | epilepsy |
| The rapidly accumulating blood puts pressure on blood vesels and interupts blood flow to the brain is called | epidural hematoma |
| Smell, taste, vision, and hearing located in the head are what kind of impulses | Special sensory impulses |
| impulses such as pain, touch, temperature and vibrations are what kind of impulses | General sensory inpulses |
| Cranial nerve I,II, and VIII contain what kind of fibers | Sensory fibers |
| Cranial nerve III, IV, VI, XI, and XII contain what kind of fibers | motor fibers |
| Cranial nerves V, VII, IX, and X contain what kind of fibers | mixed nerves |
| The ___ carries smell impulses from the receptors in the nasal mucosa to the brain. | olfactory nerve |
| The ___ is concerned with the contraction of most of the eye muscles. | oculomotor nerve |
| Cranial nerve V carries sensory inpulses from eye, upper jaw, and lower jaw toward the brain | trigeminal |
| Cranial nerve VIII caries sensory impulses for hearing and equilibrium from the inner ear towar th brain | vestibulocochlear |
| Cranial nerve XII controls the muscles of the tongue | hypoglossal |
| The ___ or eardrum, is at the end of the external auditory canal. | tympatic membrane |
| in static equilibrium each receptor is called a | macula |
| The receptors for ___ function when the body is spining or moving in different directions. | dynamic equilibrium |
| the receptors located at the base of the semicircular canals are called | cristae |
| These tates are experienced at the tip of the tongue | sweet |
| widespread receptors tha aid in the function by the internal ear's equilibrium receptores | proprioceptors |
| When sensory receptors are exposed to a continuous stimulus receptors often adjust themselves so that the sensation becomes less acute | sensory adaptation |
