SMOOTH MUSCLE– 1
Smooth muscle fibers, unlike other types of muscle cells, are spindle-shaped, their ends are pointed, as can be seen in several fibers of the images. However, their shape can not always be clearly perceivedn in sections because they stay often very close together.
The images show diagrams and photomicrographs of cross-wise and longidudinal-sectioned smooth muscle fibers.
Notice the central position of their nucleus, usually placed where the cell is thickest. For this reason nuclei are not seen in some cross-sectioned sectioned fibers, as they are cut at random and the section often capture cell nuclei.
