Question

what structure(s) act to draw a released secondary oocyte (egg) into the uterine tube?
a follicle
b corpus luteum
c fimbriae
d zona pellucida

Explanation:

• Follicle: It is involved in the development and maturation of the oocyte, not in drawing it into the uterine tube.
• Corpus luteum: Forms after ovulation and is related to hormone production (progesterone), not the transport of the oocyte.
• Fimbriae: These are finger - like projections at the end of the uterine tube. They have cilia that create a current to "sweep" or draw the released secondary oocyte (egg) into the uterine tube.
• Zona pellucida: It is a glycoprotein layer around the oocyte that is involved in fertilization (e.g., sperm binding), not in the transport of the oocyte into the uterine tube.

Answer:

C. Fimbriae
