1. contained within the cranium
  2. brain and spinal cord
    central nervous system (CNS)
  3. clear, colorless fluid contained in ventricles; cushions brain and spinal cord from shock, transports nutrients, and clears metabolic waste
    cerebrospinal fluid (CSF)
  4. largest portion of the brain; divided into left and right hemispheres
  5. three layers of membrane that cover the brain and the spinal cord
  6. cordlike structure that carries impulses from one part of the body to another
  7. system of nerves extending from the brain and spinal cord
    peripheral nervous system (PNS)
  8. passes through the vertebral canal; conducts nerve impulses to and from the brain
    spinal cord
  9. disease charaterized by early dementia, confusion, loss of recognition of persons or familiar surroundings, restlessness, and impaired memory
    Alzheimer disease (AD)
  10. jarring or shaking that results in injury; may be caused b slight or severe head injury; symptons include vertigo, headache, and loss of consciousness
  11. disorder caused by inc. amoount of CSF in the ventricles of the brain, which cause enlargement of the cranium in infants
  12. diagnostic procedure performed by insertion of a needle into the subarachnoid space usually between the 3rd and 4th lumbar vertebrae
    lumbar puncture (LP)
  13. degenerative disease characterized by sclerotic patches along the brain and spinal cord
    multiple sclerosis (MS)
  14. paralysis from the waist down caused by damage to the lower level of spinal cord
  15. chronic degenerative disease of the central nervous system; symptoms include resting tremors of the hands and feet; rigidity, expressionless face, and shuffling gait
    Parkinson disease (PD)
  16. sudden attack with an involuntary series of contractions
    seizure (convulsion)
  17. disorder caused by interruption of blood supply to a region of the brain, depriving nerve cells in the affected area of oxygen and nutrients; cells may be damaged or die within minutes. Speech, movement, memory, and other CNS functions may be affected in varying degrees.
    stroke (cerebrovascular accident, CVA)
  18. bleeding caused by a ruptured blood vessel just outside the brain(usually a ruptured cerebral aneurysm) that rapidly fills the space between the brain and skull(subarachnoid space) with blood
    subarachnoid hemorrhage
  19. sudden deficient supply of blood to the brain lasting a short time; symptons may be similar to stroke, but are temporary and the usual outcome is complete recovery.
    transient ischemic attack (TIA)
  20. gland that secretes adrenaline; located above each kidney
    adrenal gland
  21. a chemical substance secreted by an endocrine gland that is carried by the blood to a target tissue
  22. clusters of endocrine tissue found throughout the pancreas, made up of different cell types that secrete the hormone insulin
    islets of Langerhans
  23. sum total of all the chemical processes that take place in a living organism
  24. long organ that lies transversely across the upper abdomen that has a role in digestion as well as hormone secretion; contains the islets of Langerhans, which perform endocrine functions
  25. pea-sized gland located under the hypothalamus near the brain; often called the master gland because it regulates many of the other glands
    pituitary gland
  26. lymphatic organ located behind the sternum; produces T cells and secretes a hormone that supports the immune system
  27. butterfly-shaped gland below the larynx on the front and sides of the trachea; secretes hormones that regulate the metabolism of carbohydrates, proteins, and fats
    thyroid gland
  28. chronic syndrome resulting from a deficiency in the hormonal secretion of the adrenal cortex
    Addison disease
  29. chronic disease involving a disorder of carbohydrate metabolism caused by underactivity of the islets of Langerhans in the pancreas and resulting in insufficient production of insulin
    diabetes mellitus (DM)
  30. a blood test to determine the amount of glucose in the blood after fasting for 8-10hrs
    fasting blood sugar (FBS)
  31. enlargement of the thyroid gland
  32. a disorder of the thyroid gland characterized by the presence of hyperthyroidism, goiter, and exophthalmos (protusion of the eyes)
    Graves disease
