Wry neck

This article is about wry neck in animals. See torticollis for the similar condition in humans. Wry neck or head tilt is a condition in which an animal's head is turned on its side, usually as a result of an inner ear infection but sometimes as a result of an injury. It is seen largely in domestic rodents and rabbits, but may also appear in dogs and other animals.

The wrynecks (genus Jynx) are a small but distinctive group of small Old World woodpeckers.Like the true woodpeckers, wrynecks have large heads, long tongues which they use to extract their insect prey and zygodactyl feet, with two toes pointing forward, and two backwards. However, they lack the stiff tail feathers that the true woodpeckers use when climbing trees, so they are more likely than their relatives to perch on a branch rather than an upright trunk.

Medically called spasmodic torticollis, or torticollis. The most common of the focal dystonias. In torticollis, the muscles in the neck that control the position of the head are affected, causing the head to twist and turn to one side. In addition, the head may be pulled forward or backward.
