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 disection.

How does the heart of a double pithed frog contract in an organized manner after the nervous system is destroyed?
The nervous system is part of the respiratory and circulatory system. It is the brain, spinal cord, and nerves. When the nervous system is destroyed the heart of a double pithed frog contracts in an organized manner. This is exemplified in other animals as well for instance in alligators because the nerves for some time after death continue to fire. The firing of nerves send electrical signals to the heart and therefore pump it.
Can a stretch reflex be elicited in a pithed animal?
In biology class we used to pith frogs before we dissect 'em. Using a pin, we puncture a hole through their skull. Then we move the pin about to destroy the brain. I think this is supposed to make dissection less painful for the frogs. They won't feel the pain from a cutting blade if they're brain dead...i suppose. You can still test the stretch reflex even if their brain is destroyed since reflexes only need 3 components that are still intact in a pithed frog -- 1. sensory afferent fiber 2. control center (spinal cord) 3. motor efferent fiber

What does pithed mean?
Pithed means to remove the pith from the spinal cord, effectively paralyzing and most likely killing the organism. This technique is used many times with frogs to assure the subject is brain dead before tests can be run on nerves. They are terminated before the beginning of the experiment to have fresh nerves to run compound action potential tests on.
