The lateral line system of sense organs the characteristic amphibian type of lateral line system is a series of lines of superficial sense stensio's analysis . Because of its lucid structure and its small cell number, the lateral line system of xenopus is well suited for a quantitative analysis of morphogenesis at the cellular level. The canals of the mechanosensory lateral line system are components of the dermatocranium, and demonstrate phenotypic variation in bony fishes widened lateral line canals evolved convergently in a limited number of families of teleost fishes and it had been hypothesized that they evolved from narrow canals via heterochrony and explore modularity in the lateral line system.
View notes - lecture 3 - the lateral line from eeb 382 at university of toronto lecture #3: the lateral line system - we don't understand much about it. The lateral line system is visible on the surface of the skin by the presence of small pores known as mechanosensory neuromasts vibrations in the ocean are . In addition to its utility for the analysis of the development of the lateral line system (neuromasts and canals), this material is also suitable for analyses of other aspects of the teleost head, including the skeleton, sensory systems (olfactory organs, taste buds, ear, retina) and central nervous system.
The lateral line is a sensory system that allows fishes to detect weak water motions and pressure gradients the smallest functional unit of the lateral line is the neuromast, a sensory structure that consists of a hair cell epithelium and a cupula that connects the ciliary bundles of the hair cells with the water surrounding the fish. Morphology of the mechanosensory lateral line system in theatlantic stingray, dasyatis sabina: the mechanotactile hypothesis karen p maruska and timothy c tricas department of biological sciences, florida institute of technology,. The lateral line system of fish and amphibians detects water flow with receptors on the surface of the body although differences in the shape of these receptors, called neuromasts, are known to influence their mechanics, it is unclear how neuromast morphology affects the sensitivity of the lateral . The lateral line system is also implicated in these behaviors, however, most previous studies failed to examine potential effects of cobalt chloride on chemosensory systems fishes use multisensory signaling during social interactions and this information is integrated in the brain to produce context-appropriate behaviors.
The state of our knowledge of wave analysis with the lateral line system in amphibians is reviewed knowledge is based largely on tests with the clawed frog, xenopus laevis, and a few comparative . Stimuli for the lateral line system with the aid of which the fish, according to the above hypothesis, can scan its mathematical analysis of the stimulus for the . 1 the lateral-line nerves of trout as well as those of catfish are found to discharge impulses spontaneously at a high frequency 2 the frequency of nerve impulse discharge is measured as a function of the number of participating receptor groups (lateral-line sense organs) a quantitative analysis .
The lateral line system provides an overview of the key concepts and issues surrounding the development, evolution, neurobiology, and function of the lateral line, a fascinating yet somewhat enigmatic flow-sensing system. The lateral line system provides a valuable context for novel analyses of the relationship between developmental processes and the evolution of behaviorally and ecologically relevant phenotypes in fishes. The lateral line system is one of the principal sensory systems that guide fishes in their movements and in location of predators, prey, and social partners hearing an ear is a specialized receptor for detecting sound waves in the surrounding environment.
Lateral line system: lateral line system, a system of tactile sense organs, unique to aquatic vertebrates from cyclostome fishes (lampreys and hagfish) to amphibians, that serves to detect movements and pressure changes in the surrounding water. You have free access to this content the lateral line of zebrafish: a model system for the analysis of morphogenesis and neural development in vertebrates. Recently, the migrating primordium of the zebrafish posterior lateral line has emerged as an attractive system for genetic analysis of cell migration and tissue organization and for understanding how these processes are controlled [1 – 9].
Embryonic posterior lateral line development is accomplished by the pre‐patterned posterior lateral line primordium the lateral line is an experimentally accessible model for studying mechanosensory system development and biology. Vertebrate sensory systems have evolved remarkable diversity, but little is known about the underlying genetic mechanisms the lateral line sensory system of aquatic vertebrates is a promising model for genetic investigations of sensory evolution because there is extensive variation within and . You have free access to this content single-cell analysis of somatotopic map formation in the zebrafish lateral line system.
