The figure given below depicts a diagrammatic sectional view of the female reproductive system of humans. Which one set of three parts out of I – VI have been correctly identified?
A
(I) Perimetrium, (II) Myometrium, (III) Fallopian tube
B
(II) Endometrium, (III) Infundibulum, (IV) Fimbriae
C
(III) Infundibulum, (IV) Fimbriae, (V) Cervix
D
(IV) Oviducal funnel, (V) Uterus, (VI) Cervix
Detailed Solution
In the diagram, III points to the funnel-shaped part of the Fallopian tube lying close to the ovary: the infundibulum.
IV points to the finger-like projections at the edge of the infundibulum, which help in collecting the ovum after ovulation: the fimbriae.
V points to the narrow lower part of the uterus that opens into the vagina: the cervix.
The other sets each contain a wrong identification: III is the infundibulum rather than the Fallopian tube as a whole, IV is the fimbriae and not the oviducal funnel, V is the cervix and not the uterus, and VI marks the vagina and not the cervix.
Hence the correctly identified set is (III) infundibulum, (IV) fimbriae, (V) cervix.
IV points to the finger-like projections at the edge of the infundibulum, which help in collecting the ovum after ovulation: the fimbriae.
V points to the narrow lower part of the uterus that opens into the vagina: the cervix.
The other sets each contain a wrong identification: III is the infundibulum rather than the Fallopian tube as a whole, IV is the fimbriae and not the oviducal funnel, V is the cervix and not the uterus, and VI marks the vagina and not the cervix.
Hence the correctly identified set is (III) infundibulum, (IV) fimbriae, (V) cervix.
