The cloaca is connected internally to a chamber called the proctodeum a modified rectum , which in turn is linked to the intestine and the gonad MaleIntroFIG 1A. Examining male anatomy or gene expression patterns on any significant scale from such cultures is therefore impractical. Serotonin-deficient mutants and male mating-behavior in the nematode Caenorhabditis elegans. Glia-derived neurons are required for sex-specific learning in C. Some are sex-specific and while others are present in both sexes but modified in the male the sphincter and anal depressor muscles to accommodate the dual role of the proctodeum in defecation and ejaculation Sulston and Horvitz, ; Sulston et al.

Karyotyping was 46 XY. There are also neurons common to both male and hermaphrodite nervous systems that exhibit sexually dimorphic synaptic patterns or morphology e. The dauer larva, a postembryonic developmental variant of the nematode Caenorhabditis elegans. The pointed leptoderan tail tip retracts generating a blunt-ended peloderan tail. The cell lineage of the male, from egg to adult, has been determined and, like the hermaphrodite, appears to be largely invariant between individuals Sulston and Horvitz, ; Sulston et al. Post-embryonic cell lineages of the nematode Caenorhabditis elegans. Blue labels indicate differences between sexes at hatching. On examination left testicle was not palpable in the scrotum or inguinal canal. Reconstruction of the whole male nervous system from serial EM sections as per the hermaphrodite White et al. Tail sensory structures blue are required for this step. Click on picture to watch movie. Besides the large repertoire of behavior seen in hermaphrodites foraging; feeding; defecation; dauer larva formation; sensory responses to touch, smell, taste, and temperature, social behavior, and learning and memory males display some other complex behaviors like male mating Rankin, ; de Bono, The adult male gonad consists of a single J-shaped arm that connects to the cloaca rectal epithelial tube of the proctodeum. Natural variation and copulatory plug formation in Caenorhabditis elegans. The male's copulatory apparatus, which consists of several structures, is also established in the tail. Examining male anatomy or gene expression patterns on any significant scale from such cultures is therefore impractical. Barr body test was negative. Internally, rectal epithelial cells B , F , U , Y , K and K' divide to produce the cloaca and spicule channels of the proctodeum, replacing the simple larval rectum see Male Epithelial System - The Proctodeum. Evidence of a mate-finding cue in the hermaphrodite Caenorhabditis elegans. Most sex-specific differences are established after hatching, over the course of larval development. Alternatively, P0s can be taken from him-5 or him-8 strains. Currently, the only tissues thought to be sex-indifferent are the pharynx , excretory system and main body muscles Sulston and Horvitz, ; Sulston et al. Muscles and neurons are also associated with the proctodeum. Worm Breeders Gazette Consequently, males occur infrequently in cultures propagated by hermaphrodite self-fertilization ca. During larval development M generates additional ccs in both sexes. Molecular approaches to aggregation behavior and social attachment.
