B. occurs as a result of irritation of specific receptors - nociceptors or with strong irritation of receptors of different modalities. Chemicals are involved in receptor stimulation (substance „P enkephalins).

In obstetric practice, it is very important to determine the degree and nature of pain, becausethey are sometimes crucial in making a diagnosis or in choosing a methodpain relief childbirth.The assessment of the degree of pain by the patient himself is purely subjective.
