Physiology - Central Nervous System Part 4

(Нормальная Физиология - центральная нервная система)
An experiment using a live frog to study the EFFECTS OF DIFFERENT STRENGTHS OF STIMULUS ON THE TIME OF REFLEX.

--------------------------------
Part 4 - Removal of the receptors and its effects on the reflex arc

If we remove or destroy any critical parts of the reflex arc, the reflex will never occur. In this video, it is proven that when we peel off the frog's skin (where the receptors,which is a critical component of the reflex arc, are situated), no reaction can be detected.

Spinal cord, being the central portion of the reflex arc, when removed will also give the same result ( please proceed to the next part, Part 5 ).

*Early warning: If you are not strong enough just don't watch. Don't try to raise the issue of 'animal rights' here, because this frog had sacrificed its life for the sake of science.

you dont need to do this to learn about reflex arcs. This seems to be a pointless exercise and is causing pain to the animal for no real reason. Why use a frog? Why not use a human?

then blame the teacher. not me. idiot.

then we should use a brainless human like u, so it'll be useful.

thanks for the vid. you saved my from my anatomy and physiology laboratory activity.

lol thats hysterical
