Question

When an electric shock is given to the leg of a pithed frog it

• A. Blinks its eyes
• B. Shows no response
• C. Put out its tongue
• D. None of the above

Answer 1

The correct option is B Shows no response

A pithed frog is a frog that has its spinal cord or cerebral cortex pierced, severed or scrambled in order to kill it or make it insensible (for experimental purposes such as dissection). If the frog is brain-pithed, it will only respond to touch, electric shock, heat and chemical stimuli. If the frog is totally pithed, then it would not respond to any of the stimuli. Assuming, in the question, the frog is totally pithed, it won't respond to any stimuli or it has lost its ability to react to any stimuli.
So, the correct answer is option B.
