Sažetak
According to the World Health Organisation (WHO), pain is defined as “an unpleasant sensational and emotional experience related to real or potential tissue injury”. Painful stimuli can be classified according to their duration (acute or chronic), mechanism of onset (organic or psychogenic), cause (nociceptive or neuropathic) and location (visceral or parietal) or according to general cause (benign or malignant). Anatomy and physiology recognise four stages of pain: transduction, conduction, modulation and perception. Neurotransmitters, such as noradrenalin and acetyl-colin, are located at the synaptic nerve endings, whereas dopamine is found in the central nerve system. The second group of neurotransmitters are transmission modulators such as histamine, glutamate and aspartate in the nerve endings, and GABA and endogenous opioids in the central nervous system. The nociceptive behavioural response produced by animals can be a reflexive or voluntary response, or chronic pain. Two basic tools for pain assessment in animals are subjective evaluation of pain and algesimeters.
