FROG BRAINS Starting  at the  most  anterior  part of the  head,  the  olfactory  nerves  connect  to the  nostrils  and  then  to the   olfactory lobes  (A)  where  odors  are  proce s s e d.   Just  posterior  to the  olfactory  lobes  are  two elongate  bodies  with rounded  base s,  this  is the   cerebrum  (B),  and  it is the  frog’s  thinking  center.   The  cerebrum  is the   part of the  brain  that helps  the  frog  respond  to its environm e nt.    Posterior  to the  cerebrum  are  the   optic lobes  (C),  which  function  in vision.    The  ridge  just   behind  the  optic  lobes  is the   cerebellum  (D),  it is used  to coordinate  the  frog’s  muscle s  and  maintain  balance.  Posterior  to the  cereb ellum  is the   medulla oblongata  (E)  which  connects  the  brain  to the   spinal cord  (F).
