Question

What happens if ophthalmic branch of trigeminal is cut in frog?

• A. Frog dies
• B. Frog becomes blind
• C. Frog loses its capacity of sensing
• D. Frog loses its capacity of hearing

Answer 1

The correct option is C Frog loses its capacity of sensing

• In frogs, the trigeminal nerve is the largest cranial nerve which originates from the sides of the anterior end of the medulla oblongata in the brain.
• It is separated into three different branches are ophthalmic, mandibular, and maxillary.
• The ophthalmic branch is responsible for somatic sensory. If it is cut down in a frog, it loses its somatic sensing, which includes vibration, pressure, light detection, temperature stimuli, etc.

Hence, the correct answer is option C, i.e., Frog loses its capacity of sensing.
