5 Matching questions

  1. sympathetic division
  2. brain stem
  3. arachnoid mater
  4. spinal nerves
  5. limbic system
  1. a "emotional brain"; system of functionally related neural structures in brain that regulate and produce emotional behavior; hypothalamus is a key component
  2. b middle layer of meninges; cerebrospinal fluid and blood vessels found here;
    "spiderweb-like mother"
  3. c 31 pairs of nerves arising from the spinal cord;
    named for location on vertebrae (8C, 12T, 5L, 5S, 1C);
    composed of 2 roots: dorsal and ventral
  4. d "fight-or-flight" division of ANS;
    expends energy;
    mobilizes body for action (ie, heart rate increase, blood vessels dilate, glucose released into blood, etc);
  5. e midbrain, pons, and medulla oblongata;
    brain regions connecting "higher" brain regions and spinal cord

5 Multiple choice questions

  1. neuron that detects specific information about environment (stimulus) and conducts information encoded in action potentials via ascending tracts to the CNS;
    aka Affarent neuron
  2. brain region containing thalamus and hypothalamus;
    hypothalamus is an integral part of the limbic system, and thalamus is functionally connected to limbic system
  3. "rest-and-digest" division of ANS;
    conserves energy; increases digestion and absorption and relaxtion (ie, heart rate slows, glucose is stored, etc)
  4. detect environment (internal or external) & relays info to CNS;
    aka afferent receptors
  5. watery fluid in and around brain and spinal cord;
    produced in brain ventricles;
    performs the functions of blood in the brain (ie carries nutrients, hormones, waste products, gases, etc)

5 True/False questions

  1. dura materhard thick outer layer of meninges;
    "hard mother"

          

  2. ascending tractbundles of axons sending motor commands "down" to muscles

          

  3. subdural spacesmall space below dura mater

          

  4. reflexinvoluntary response to a stimulus, such as knee-jerk response

          

  5. cerebrum"little brain" in the inferior posterior portion of brain; controls and coordinates body movement (and all that goes along with it)
