Detailed Explanation of Each Match
- 1. Os-phrenic → (b) Camel: Os-phrenic is a visceral bone found in the diaphragm of the camel — a unique anatomical feature.
- 2. Os-penis → (d) Dog: Os-penis (baculum) is a heterotopic bone found in the penis of dogs (and other carnivores). It supports penile rigidity independently of blood engorgement.
- 3. Wolffian duct (Mesonephric duct) → (c) Male genitalia: The Wolffian (mesonephric) duct differentiates into the male reproductive tract under testosterone influence — forming epididymis, vas deferens, seminal vesicles.
- 4. Mullerian duct (Paramesonephric duct) → (f) Female genitalia: The Mullerian duct differentiates into the female reproductive tract — forming fallopian tubes, uterus, cervix, and upper vagina.
- 5. Cortical cords → (a) Sex cords of female: In the developing ovary, the cortical cords become the sex cords of the female — these give rise to follicle cells and granulosa cells.
- 6. Os-cordis → (e) Cattle: Os-cordis is a heterotopic visceral bone found in the heart (cardiac skeleton) of cattle — specifically in the fibrous ring at the base of the aorta.
