- bursa swollen
The adult male tail, including the lateral fan and rays, appears bloated or distended.
- male tail development variant
Any variation in the process whose specific outcome is the progression of the male tail over time, from its formation to the mature structure, compared to control.
- male tail curling serotonin variant
Any variation in the posture of the male tail after application of exogenous serotonin compared to control. In C. elegans, males respond with a tight ventral curling of the male tail in response to serotonin.
- male tail morphology variant
Animals exhibit variations in the structure or organization of the somatic reproductive components of the posterior segment of the male from that observed in control males. In C. elegans, this region of the male includes the terminal canals of the reproductive tract, the digestive tract, and spicule channels along with the male specific sensilla (ray, post-cloacal, hook and spicule) and extends to the tip of the acellular fan.
- male tail sensory ray development variant
Any variation in the progression of the finger-like sensory sensilla that project from the tail and embed in the male fan from its formation to the mature structure when compared to control animals.
- pointed tail tip male
Male tails fail to undergo tip retraction thereby forming a 'leptoderan' or 'pointed' adult tail.
- over retracted male tail
Adult males exhibit a truncated tail, often without a fan or have well-developed fans but squarish, truncated back ends compared to control. In C. elegans this is due to precocious male tail tip retraction beginning in the early L3 stage (normally retraction begins in the L4 stage). Condition can be lethal if the function of the anus is affected.
