The motor neurons of the autonomic nervous system…..  

  Excess CSF is removed from the subarachnoid space by…  

  BONUS #5:    Which is an exclusively sympathetic function?  

  The portion of the brain involved primarily with vision is found in what lobe?  

Projection tracts….  

  This portion of the brain ensures that skeletal muscle contraction follows the correct pattern leading to smooth, coordinated movements.  It is the part of the brain that does not initiate somatic motor movements, but rather coordinates and fine-tunes those movements.  

  Just like your eyeballs, please protect your sense of hearing… take this advice from someone who’s been around too many loud jets, gunfire, and loud concert speakers.  The sensation of loudness or the volume of a sound is detected by ________.   

  BONUS #7:    We can touch our finger to our nose while our eyes are closed in part because we can sense the position and movement of our joints as well as the length of stretch in our muscles.  These sensations create awareness of our body’s positioning.  The following receptors are most likely responsible for this ability.  

  In most cases, sound gets to our ears thru the air (= gas) and these pressure waves eventually get directed to the liquid environment (endolymph/ perilymph) of the inner ear.  Due to this transition (from gas to liquid), the signal requires amplification… this structure, along with its two close “cousins” nearby, help increase the vibrations going into the cochlea.
