Final answer:
Deep somatic pain originates from the bones and joints, contrasting visceral pain which comes from internal organs and can lead to referred pain.
Step-by-step explanation:
The source of deep somatic pain is bones and joints. While the skin and subcutaneous tissues can generate pain, the type of pain emanating from these areas is typically considered to be superficial pain. Deep somatic pain usually stems from structures deep within the body, such as bones, joints, and muscles. Pain from the pancreas or intestines would be categorized as visceral pain, not deep somatic pain. Visceral pain can sometimes lead to referred pain, whereby the pain is felt in an area different from the source organ. Somatic pain is more localized and easier to pinpoint than visceral pain.
