A fatty acid chain that plays a key role in pain signaling.

Chemical messengers released by cells in response to injury.

Pathway for converting arachidonic acid into prostaglandins.

A metabolite of arachidonic acid involved in promoting inflammation.

Non-steroidal anti-inflammatory drugs that inhibit pain pathways.

Medications that specifically block the cyclooxygenase enzymes.

Substances that relieve pain without causing anesthesia.

Cells that engulf and digest pathogens but avoid healthy cells.

A long-standing sore that develops fibroblastic proliferation and scarring.

Increased growth of fibroblasts leading to tissue repair and scarring.

A delayed immune response characterized by tissue damage due to immune cell activation.

A serious complication where an ulcer causes a hole in a hollow organ.

Inflammation of the peritoneum caused by leakage of organ contents, often due to perforation.

Diseases where the immune system attacks the body’s own tissues, leading to chronic inflammation.

Accumulation of various white blood cells at the site of injury or infection.

Hypersensitivity is an exaggerated immune response, while an allergy is a specific hypersensitivity to allergens.
