front 1 Function of nervous system: | back 1 Keeps us in touch with both our internal and external environments. Serving as the control center and communications network, the nervous system stores and processes information, stimulates movement, and detects change. |
front 2 psychology | back 2 The study of behavior and the function and processes of the mind |
front 3 Sensory | back 3 afferent, receptors detect changes that occur inside and outside the body and convey them to the brain |
front 4 Motor | back 4 efferent, signals from the brain to muscles and glands to cause an effect. |
front 5 The part of the nervous system under conscious or voluntary control is called the | back 5 somatic nervous system |
front 6 The part of the nervous system that relates to involuntary or automatic body functions is called the | back 6 autonomic nervous system. |
front 7 Two major divisions of the nervous system: | back 7 the central nervous system (CNS) and the peripheral nervous system (PNS) |
front 8 The nervous system is composed of two types of cells: | back 8 neurons and glial (neuroglial) cells. |
front 9 Neurons: | back 9 conduct impulses either to or from the nervous system |
front 10 • Neuroglia, or glia: | back 10 the supporting tissue cells of the nervous system that provide special support and protection. |
front 11 sciatic nerve | back 11 actually two nerves bound together; it is often considered the largest nerve in the body |
front 12 epidural hematoma | back 12 blood accumulates in the epidural space, the space outside the dura mater |
front 13 Accumulation of blood beneath the dura mater is called: | back 13 subdural hematoma |
front 14 intracerebral hematoma | back 14 bleeding occurs within the brain |
front 15 cerebro+vascul+ar accident (CVA), | back 15 normal blood supply to the brain is disrupted. results in insufficient oxygen to brain tissue and is caused by hemorrhage, occlusion (closing), or constriction of the blood vessels that normally supply oxygen to the brain. |
front 16 transient ischemic attack (TIA) | back 16 caused by a brief interruption in cerebral blood flow. |
front 17 hydrocephalus | back 17 accumulation of fluid in the skull. |
front 18 akinesia | back 18 (a-, no + kinesi/o, movement + -ia, condition) Complete or partial loss of muscle movement. |

front 20 aphagia | back 20 (a-, no + -phagia, eating) Inability or refusal to swallow; characterized by abstention from eating because swallowing is painful. |
front 21 aphasia | back 21 (-phasia, speech) An abnormal neurologic condition in which there is absence or impairment of the ability to communicate through speech, writing, or signs. |
front 22 bradykinesia | back 22 (brady-, slow + -kinesia, movement) Abnormal slowness of movement or sluggishness of mental and physical processes. |
front 23 brain tumo | back 23 r A neoplasm of the intracranial portion of the CNS; may be primary or secondary (metastasized from another area) |
front 24 dysphasia | back 24 (-phasia, speech) Speech impairment caused by a lesion in the brain; characterized by lack of coordination and failure to arrange words properly. |
