Networks of regularly arranged tubular units and lamellar structures were observed in the degenerating tail muscle fibers of spontaneously metamorphosing anuran tadpoles. These networks appeared to be similar to those previously found in the skeletal muscle of other animals under abnormal conditions. They...
Actin-Based Cytoskeletal Structures Were First Described in Muscle Tissue Actin, first isolated from skeletal muscle, was originally thought to be a protein found exclusively in muscle tissue. However, actin is a component of all cells, representing 5% to 30% of the total protein in nonmuscle ce...
Most of the reported resistance mutations against diamide insecticides cluster in a region near its binding site (Fig. 4a). Among them, I4790M and G4946E (DBM numbering) are the two most commonly observed resistance mutations and are often found together. When this double mutation was introduce...
found in ganglia even after their definitive formation. If a cholinergicciliary ganglionor sensory ganglion is transplanted to the trunk region of an appropriately aged host, ganglionic cells migrate to and can be found exhibitingcatecholaminefluorescence in sympathetic ganglia (Le Douarinet al.,1978)...
How does the skeletal system work with the circulatory system? What organs make up the cardiovascular system? What body system is the heart in? What type of circulatory system does a frog have? What type of circulatory system is found in most mollusks?

The pharynx is a tube formed by skeletal muscle and lined with a mucous membrane that is continuous with that of the nasal cavities. The pharynx is divided into three major regions: the nasopharynx, the oropharynx, and the laryngopharynx. ...

Sensory smart structure attributes are found in even the simplest single-cell micro-organism (Figure 17A). A bridge fitted with smart structure characteristics has been conceptualized. Such a ‘smart’ bridge (Figure 17B) would be expected to ‘sense’ the environment, react accordingly, and ‘tel...
