The neural pathways for touch-induced movement in Caenorhabditis elegans contain six touch receptors, five pairs of interneurons, and 69 motor neurons. The synaptic relationships among these cells have been deduced from reconstructions from serial section electron micrographs, and the roles of the cells were assessed by examining the behavior of animals(More)
The nervous system of Caenorhabditis elegans is arranged as a series of fibre bundles which run along internal hypodermal ridges. Most of the sensory integration takes place in a ring of nerve fibres which is wrapped round the pharynx in the head. The body muscles in the head are innervated by motor neurones in this nerve ring while those in the lower part(More)
The genes involved in the inductive interactions that specify cell fates in the vulva of Caenorhabditis elegans are known in some detail. However, little is known about the morphogenesis of this organ. Using a combination of cell biological and anatomical approaches, we have determined a complete morphogenetic pathway of cellular events that lead to the(More)
Identification of the genes orchestrating neurogenesis would greatly enhance our understanding of this process. Genes have been identified that specify neuron type (for example cut and numb in Drosophila and mec-3 in Caenorhabditis elegans) and process guidance (for example, unc-5, unc-6 and unc-40 in C. elegans and the fas-1 gene of Drosophila). We sought(More)
The nervous system of C. elegans is arranged as a collection of process bundles. Processes within bundles are generally unbranched and occupy defined positions relative to their neighbors. Small groups of processes are often closely associated together and run adjacent to one another for relatively long distances. We have defined the set of neurons that(More)
The nervous system of the nematode worm Ascaris contains about 250 nerve cells; of these, the motoneurons consist of five segmental sets, each containing 11 cells. Morphologically, the motoneurons can be divided into seven different types. Their geometry is simple: some are unbranched, others have one branch point, and the most complex have two. There is no(More)
Introduction Few studies have examined the role of RTW Coordination from the perspective of RTW Coordinator’s. Furthermore there is little health specific literature on returning injured nurses to work despite the critical workforce shortages of these professionals. The study aimed to examine barriers and facilitators identified by the RTW Coordinator to(More)
Clinical Prediction Rules (CPRs) have been developed to assist in the physiotherapy management of low back pain (LBP) although little is known about the factors that may influence their implementation in clinical practice. This study used qualitative research methodology to explore the knowledge, attitudes and practices/behaviours of physiotherapists in(More)
OBJECTIVES This study was designed to elucidate why students from backgrounds of lower socio-economic status (SES) and who may be first in their family (FIF) to enter university continue to be under-represented in medical schools. METHODS Academically able high school students (n = 33) from a range of socio-economic backgrounds participated in focus(More)
OBJECTIVE To describe methadone injectors and the risk practices associated with injecting methadone in New South Wales, Australia. To assess the impact on injecting drug use and risk behaviour of the withdrawal of methadone injecting equipment from government-funded needle and syringe programs. METHOD Cross-sectional survey, conducted in 1999, of 206(More)
