               QUESTIONS

               In the following multiple choice questions, choose the letter corresponding to the
               one best answer.


                 1.  What is main function of the acrosome reaction?

                       A.  To activate the oocyte to undergo the first meiotic division

                       B.  To induce capacitation of sperm in the uterine tube

                       C.  To block polyspermy

                       D.  To release hydrolytic enzymes from sperm to penetrate the oocyte

                       E.  To increase sperm motility

                 2.  During the proliferative phase of the menstrual cycle, what changes are

                      seen in the uterine wall?

                       A.    Growth  and  resurfacing  of  the  basalis  layer  to  form  a  new
                            functionalis layer

                       B.  Increased accumulation of fluid in the endometrium

                       C.  Constriction and expansion of the spiral arteries in the functionalis
                            layer


                       D.  Increased accumulation of nutrients in glands

                       E.  Blood flow to the basalis layer is reestablished

                 3.  During the menstrual phase of the menstrual cycle, what changes take
                      place in the endometrium?

                       A.  The basalis layer exhibits increased connective tissue proliferation.

                       B.    The  functionalis  layer  degenerates  due  to  ischemia  (lack  of  blood

                            supply).

                       C.  The spiral arteries are coiled and highly dilated.

                       D.    The  arteries  in  the  basalis  layer  cut  off  blood  supply  to  the
                            endometrium.

                       E.  The basalis and functionalis layers become ischemic and are shed.
