- male nervous system morphology variant
Male animals exhibit variations in the structure or organization of any component that is part of the complement of organ tissues that serve to detect, relay and coordinate information about an animal's internal and external environments and to initiate and integrate its effector responses and activities, compared to that in control animals.
- male nervous system development variant
Variations in the progression of a set of interacting or interdependent entities forming the male nervous system over time from an initial condition to a later condition compared to control animals. The nervous system is involved in the coordination and control of bodily activities and the interpretation of information from the senses.
- pharyngeal nervous system development variant
Variations in the progression of a set of interacting or interdependent entities forming the pharyngeal nervous system over time from an initial condition to a later condition compared to control animals. The nervous system is involved in the coordination and control of bodily activities and the interpretation of information from the senses.
- axon trajectory variant
Animals display variations in the directed path taken by the axon compared to the path the nerve fiber follows in the nervous system in control animals.
- male sex muscle development variant
Variations in the progression of the muscles of the adult male reproductive system over time form their initial formation to their mature structure compared to control.
- male reproductive system morphology variant
Any variations in the form, structure or composition of a set of interacting or interdependent entities forming the male reproductive system compared to control. The reproductive system is involved in the generation of progeny which contain genetic material inherited from the parents.
- masculinized
Animals that are not ordinarily male, exhibit male-specific attributes. In C. elegans, XX animals exhibit male-specific attributes.
- linker cell absent
The gonads of male animals do not produce the linker cell involved in guiding the developing male gonad to the sex organs in the male tail.
- neuron degeneration
Cells specialized for receiving, conducting and transmitting impulses in the nervous system are observed to undergo a dramatic decrease in cell volume, collapse of the vacuoles and processes, and complete disintegration of the plasma membrane and most organelles.
- linker cell detached
The linker cell of male animals becomes detached from the rest of the male gonad.
