question 39

Multiple Choice

Which is the correct order of events leading to the luteinizing hormone surge?

• A) Copulation stimulates sensory neurons in the cervix → a surge of LH stimulates ovulation in the ovaries → GnRH stimulates anterior pituitary cells to secrete LH → neuronal impulses release norepinephrine
• B) Copulation stimulates sensory neurons in the cervix → a surge of LH stimulates ovulation in the ovaries → neuronal impulses release norepinephrine → GnRH stimulates anterior pituitary cells to secrete LH
• C) Copulation stimulates sensory neurons in the cervix → neuronal impulses release norepinephrine → GnRH stimulates anterior pituitary cells to secrete LH → a surge of LH stimulates ovulation in the ovaries
• D) GnRH stimulates anterior pituitary cells to secrete LH → copulation stimulates sensory neurons in the cervix → a surge of LH stimulates ovulation in the ovaries → neuronal impulses release norepinephrine
