Q

What occurs in transmission?

A

When the noxious stimuli exceed the nociceptor’s threshold, a nerve impulse is generated and transmitted along the peripheral nerves to the spinal cord

A

There are misconceptions about animals and pain, especially when it comes to large animals.

97
Q

Why is it thought that an animal is experiencing more severe pain if they are showing obvious signs such as vocalizing?

A

5 SF

Animals have the natural instinct to hide pain to avoid seeming vulnerable to predators. So, if an animal is showing obvious signs of pain, it is likely that they are no longer able to hide it because the pain is more severe.
