In frogs, the number of pairs of cranial nerves arising from the brain are _______.

• A. 12
• B. 6
• C. 9
• D. 10

Hint:

Remember comparative anatomy: Humans = 12 pairs cranial nerves Frog = 10 pairs cranial nerves

Answer 1

The Correct Option is D

Step 1: Define cranial nerves.
Cranial nerves arise directly from the brain and control sensation, movement and coordination.
Step 2: Note their jobs.
They handle functions like vision, smell, hearing, swallowing and muscle movement.
Step 3: Recall the human number.
Humans have 12 pairs of cranial nerves.
Step 4: Recall the frog number.
Frogs have fewer than mammals, with 10 pairs of cranial nerves.
Step 5: Reject the distractors.
12 is the human value, while 6 and 9 are simply incorrect.
Step 6: Conclude.
Frogs have 10 pairs of cranial nerves, which is option 4.
\[ \boxed{10} \]
