Choose the correct statements regarding frog’s anatomy:
A. Hepatic portal system is the special venous connection between liver and intestine.
B. There are twelve pairs of cranial nerves arising from the brain.
C. The ureters and oviducts open separately into the cloaca in female frogs.
D. Hind-brain consists of cerebellum, medulla oblongata and optic lobes.
E. Sinus venosus joins the right atrium of heart.
Choose the correct answer from the options given below:
- A
A, B and C only
- B
B and D only
- C
B and C only
- D
A, C and E only
In frogs the special venous connection between liver and intestine is called the hepatic portal system, so A is correct.
Frogs have ten pairs of cranial nerves, not twelve, so B is incorrect.
In female frogs, the ureters and oviducts open separately into the cloaca, so C is correct.
In frogs the midbrain has the optic lobes; the hindbrain only contains cerebellum and medulla oblongata, so D is incorrect.
The sinus venosus is a triangular structure that joins the right atrium, so E is correct.
Correct set: A, C and E.
