__rostral__________________ toward the nose
__medial__________________ toward the midline
__afferent__________________
projecting toward a point of reference
__ipsilateral__________________ on the same side of the body
2. The ventricles of the brain are filled with the fluid called _cerebrospinal fluid_________________,
which is made in a specialized bed of blood vessels that lines the ventricles called the _choroid
plexus_____________.
3. The part of the eye that does the major, coarse focusing of light is the
__cornea___________________.
4. Two competing theories of color vision are the __trichromatic theory_____________, which is
based on the relative activity of the different kinds of retinal cones, and the __opponent process
theory_______________, which is suggested by receptive fields with center-surround
antagonism of complementary colors.
