SMOOTH MUSCLE, TEM


Cross-section of smooth muscle fibres. This type of fibre makes up the walls of certain hollow organs (stomach, intestin, uterus, bladder, etc.) and also is present in the iris and the ciliary muscles. Their contractions are involuntary and slow. As opposed to striated muscle fibre, smooth muscle fibre is characterized by non-striated myofiliaments (in yellow) and a central nucleus (red and beige). In green, mitochondria. 10,000 x color-enhanced TEM.
