Medical Terms Overview: Hangnail, Hankin's Defensive Proteids, Hannover's Canal, and Hanot's Disease

Hangnail

A Hangnail (or agnail) refers to a small, torn piece of skin next to a fingernail or toenail. It results from dry skin or nail-biting and can lead to inflammation if irritated.

Causes and Treatment

Common causes include dry skin, exposure to harsh chemicals, and nail-biting. Treatment involves moisturizing the affected area and carefully trimming the hangnail. Avoiding nail-biting and using protective gloves can prevent hangnails.

Hankin's Defensive Proteids

Hankin's Defensive Proteids are germicidal globulins discovered by the scientist W. S. Hankin. These proteins are found in the blood of certain animals and contribute to immunity against specific toxins.

Role in Immune System

These proteids play a role in the natural defense mechanisms against infections, particularly in organisms with developed immune responses.

Hannover's Canal

Hannover's Canal refers to an artificial passage created between the anterior and posterior fibers of the zonules of Zinn in the eye. This passage is produced during certain ophthalmic procedures involving the injection of viscous fluid.

Hannover's Intermediate Membrane

Also known as the enamel membrane, this structure is part of the enamel-organ of the dental germ in the fetus, playing a role in tooth development.
