Analysis of Muscle Tissue Structure Characteristics of Onychostoma barbatum from Fanjing Mountain
Paraffin embedded tissue section and HE staining were used to study and analyze the muscle tissue of Onychostoma barbatum.The results showed that the skeletal muscle fiber of Onychostoma barbatum was different in size and irregular in shape.It contains a certain number of connective tissue,blood vessels and nerves and other structures.The connective tissue between the myocardial fibers of Onychostoma barba-tum is very developed.The myocardial fibers are arranged like smooth muscle tissue and have not obvious transverse striation.The muscle nucle-us is long fusiform and distributes in the middle.The muscle tissue structure of the Onychostoma barbatum is the same as that of the common fish,showing adaptability to its living environment,structure and function.
