The sex determination system in C. elegans is a topic that has been of interest to scientists for years. [30] Since they are used as a model organism, any information discovered about the way their sex determination system might have evolved could further the same evolutionary biology research in other organisms.
Officially titled “The structure of the nervous system of the nematode Caenorhabditis elegans,” [7] it is commonly referred to by its running title, “The Mind of a Worm.” [2] They identified 302 neurons in the hermaphrodite C. elegans worm, which they grouped into 118 classes, and they discovered that the layout and connections were ...
The UNC-119 protein plays key roles in the movement and feeding in the C. elegans, because it is essential in the development and function of their nervous system. One mutation observed was in the expression patterns when the mutant fuses with lacZ. [10]
The roundworm Caenorhabditis elegans is a free-living, transparent nematode, about 1 mm in length, [6] that lives in temperate soil environments. It is the type species of its genus. [7] An adult Caenorhabditis elegans worm. C. elegans has one of the simplest nervous systems of any organism - its hermaphrodite type possesses
The following are two lists of animals ordered by the size of their nervous system. The first list shows number of neurons in their entire nervous system. The second list shows the number of neurons in the structure that has been found to be representative of animal intelligence. [1]
In this species, the nervous system is sexually dimorphic; the nervous systems of the two sexes, males and female hermaphrodites, have different numbers of neurons and groups of neurons that perform sex-specific functions. In C. elegans, males have exactly 383 neurons, while hermaphrodites have exactly 302 neurons. [29]
The floor plate is a structure integral to the developing nervous system of vertebrate organisms. Located on the ventral midline of the embryonic neural tube, the floor plate is a specialized glial structure that spans the anteroposterior axis from the midbrain to the tail regions.
