The individual smooth muscle cell is surrounded by fine network of reticular fibers, blood vessels and nerve fibers. But in most of the cross sectional smooth muscle cells lacks the nucleus because of the extends of the cell beyond centar nuclear region. The nucleus may find in the center of these cross sectional cells (ovoid and centrally placed nucleus). ![]() Thus you will find the various shaped and sized cells in the cross section of the smooth muscle histology slide. In cross section, the spindle-shaped smooth muscle cells will cut at different places along the length of the cell. Smooth muscle cross section labeledįine, let’s know the characteristics features from the smooth muscle cross section labeled image. You will find the fibroblasts, blood vessels in the connective tissue of smooth muscle. The connective tissue surrounds the individual smooth muscle fibers as well as muscle layers. The cytoplasm of the smooth muscle cells or fibers are acidophilic (stains dark). Each cell contains a single, elongated, and centrally placed nucleus. These smooth muscle cells are tapered at the both ends. You will find the enlogated, spindle-shaped cells or smooth muscle fibers in the cross sectional histology slide. I will show you the light microscopic structure from smooth muscle longitudinal section labeled images. Smooth muscle longitudinal section labeled Want to know the details of smooth muscle? Fine, let’s continue this short guide to learn about smooth muscle. So, this is the smooth muscles histology slide (hollow organs) Many of the cross sections of the cells lack of nuclear profile, and few shows centrally placed ovoid nucleus in cross section. Presence of various shaped and sized cells (resulting from cutting spindle-shaped cells at different places) in cross section. The nucleus is elongated and placed in the centre of the smooth muscle fibers or cells (in longitudinal section) Presence of smooth muscle fibers (spindle-shaped) with tapering end in the longitudinal section. The muscle cells are arranged in bundles with their long axes aligned parallel to the direction of their contraction.įollowing are the important histological features to identify the smooth muscle histology slide under a light microscope. I will show you the characteristics features of smooth muscles fibers from both longitudinal and cross section. You may find both longitudinal and cross section in the same tissue sample in a smooth muscle histology slide. Smooth muscle histology Smooth muscle histology slide identification Connective tissue, blood vessels and fibroblast in cross section of smooth musclesįirst, you might find these histological features from the smooth muscles labeled images or the video. ![]() The nucleus of smooth muscle cells from cross-sectional tissue Connective tissue surrounds the smooth muscle fibers or cells with fibroblasts The nucleus of smooth muscle cells or fibres of the longitudinal section Smooth muscle cells or fibres of the longitudinal section ![]() From the smooth muscle histology slide, you might identify the following important histological features. These muscle cells are present in the three main areas of the vertebrate body – in the wall of hollow organs, in the skeletal system and the heart. Muscle cells are specialized cells that have a strong and concerted contraction to produce the integrated movement of the animal’s body.
