组培实验的资料（Tissue culture experiment data） Name: skeletal muscle (25 points) under light microscope: (25 points) Longitudinal muscle fibers: zonal / long column; nuclear multiple, long oval / rod-shaped, close to the subsarcolemmal The muscle fibers have light and dark stripes. (15 points) Transverse view: muscle fibers are irregularly shaped or round, with nuclei ranging from 1 to several, punctate, located in the periphery. (10 points) Name: myocardial (25 points) under light microscope: (25 points) (heart fibers are arranged in a more complex direction and see sections at the same time.) Longitudinal view: the cardiac fiber is short columnar and has branches attached to the web. The nucleus is ovoid and located in the center. Myocardium Fibers have stripes, but not as much as skeletal muscles. There is a darker line at the distance between the fibers of the myocardium Intercalated disk. (20 points) Transverse view: the fibers are round or irregular in size, with the nucleus located in the center and some not cut Nuclear. (5 points) Name: spinal cord (neurons) (25 points) under light microscope: (25 points) In the anterior horn, multipolar neurons can be seen. The soma is large and irregular in shape, and the projection of the cell body is often severed. Cells The nucleus is located in the center of the cell body. It is large and round with pale staining and prominent nucleoli. Cytoplasm purple red, cytoplasm can be seen in many A purplish blue patch of varying size, i.e., Nissl body. The dendrites contained Nissl bodies, axons, and axis mounds. Name: middle and middle vein (25 points) under light microscope: (25 points) (1) the internal and external elastic membranes of the middle artery are divided into three layers: the intima, the tunica media and the adventitia 1. the intima is thin and the endothelial cells protrude into the lumen. (the lower layer of the endothelium is an extremely thin connective tissue that is difficult to distinguish ). The inner elastic fi
