Chronic cancer pain: defined as cancer or treatment related visceral (within the internal organs), musculoskeletal, or bony pain. Chronic post-traumatic pain: pain lasting 3 months after an injury or surgery, excluding infectious or pre-existing conditions. Chronic neuropathic pain: pain caused by damage to the somatosensory nervous system. Chronic headache and orofacial pain: pain that originates in the head or face, and occurs for 50% or more days over a 3 months period. Chronic visceral pain: pain originating in an internal organ. Chronic musculoskeletal pain: pain originating in the bones, muscles, joints or connective tissue.Chronic pain may be divided into "nociceptive" (caused by inflamed or damaged tissue activating specialized pain sensors called nociceptors), and "neuropathic" (caused by damage to or malfunction of the nervous system).Nociceptive pain can be divided into "superficial" and "deep", and deep pain into "deep somatic" and "visceral". Superficial pain is initiated by activation of nociceptors in the skin or superficial tissues. Deep somatic pain is initiated by stimulation of nociceptors in ligaments, tendons, bones, blood vessels, fasciae and muscles, and is dull, aching, poorly-localized pain. Visceral pain originates in the viscera (organs). Visceral pain may be well-localized, but often it is extremely difficult to locate, and several visceral regions produce "referred" pain when damaged or inflamed, where the sensation is located in an area distant from the site of pathology or injury.Neuropathic pain is divided into "peripheral" (originating in the peripheral nervous system) and "central" (originating in the brain or spinal cord).
Women who were Vestals Virgins, were selected between the ages of 6 and 10 to serve as priestesses in the temple of goddess Vesta in the Roman Forum for 30 years after which time they could marry. Noble women were known to marry as young as 12 years of age, whereas women in the lower classes were more likely to marry slightly further into their teenage years. Ancient Roman law required brides to be at least 12 years old, a standard adopted by Roman Catholic canon law. In ancient Roman law, first marriages to brides aged 12–25 required the consent of the bride and her father, but by the late antique period Roman law permitted women over 25 to marry without parental consent. The father had the right and duty to seek a good and useful match for his children, and might arrange a childs betrothal long before he or she came of age. To further the interests of their birth families, daughters of the elite would marry into respectable families. If a daughter could prove the proposed husband to be of bad character, she could legitimately refuse the match. The age of lawful consent to a marriage was 12 for maidens and 14 for youths. In late antiquity, Most Roman women seem to have married in their late teens to early twenties, but noble women married younger than those of the lower classes, and an aristocratic maiden was expected to be virgin until her first marriage.
