head muscle dystrophy

Progressive degeneration of the head muscle.

head protrusion

Any irregular swelling in discrete regions of the head.

head cavity

The head contains cavities, possibly indicative of inappropriate cell death.

paralyzed body

All parts of the animal are immobilized except for the head.

head degeneration

Animals exhibit visible, structural degeneration of the head, unlike control animals.

occurences of decapitation

Animals exhibit constrictions in the anterior portion of the head that result in decapitation.

light touch habituation variant

Any variation in the decreased behavioral response to repeated light head or tail touch compared to control. A gentle touch to the animal's head causes backward movement, whereas a gentle touch to the animal's tail causes forward movement. When wild-type animals are touched repeatedly on the head or tail, after some repetition they stop responding to the touch stimulus.

shrinker

The whole body undergoes longitudinal shortening in response to head touch or tail touch (Wormatlas).

touch-induced suppression of head movement defective

Animals do not suppress exploratory head movements in response to anterior touch stimuli, unlike control animals.

body protrusions

Any irregular swelling in discrete regions of the body region between the head and the tail.
