Many of the striated muscle contractile proteins have homologous isoforms that are expressed in smooth muscle tissue. There is a smooth muscle-specific myosin heavy chain gene and the genes for the light chains of smooth muscle myosin differ from those of skeletal muscles. In place of well-define...
Smooth muscle cells also proliferate and migrate upon the activation of chemical and mechanical factors, which modulates tissue homeostasis and development. Unfortunately, uncontrolled vascular smooth muscle contractility results in the development of hypertension. Aberrant airway smooth muscle reactivity leads ...

smooth muscle n. Muscle tissue that contracts without conscious control, having the form of thin layers or sheets made up of spindle-shaped, unstriated cells with single nuclei and found in the walls of the internal organs, such as the stomach, intestine, bladder, and blood vessels, excluding...
Sarkar et al. directly used software to measure the size of the long axis and short axis of SMC under an optical microscope that expressed the extent of cell elongation using the aspect ratio [69]. However, most structures still impact light, which greatly reduces the clarity and reliability ...
We next investigated the impact of AMPK-α1/α2 deletion on voltage-gated potassium (KV) currents in acutely isolated pulmonary arterial smooth muscle cells, because reduced activity and/or expression of KV1.5 has been identified as a hallmark of persistent pulmonary hypertension in neonates52,53an...
it appears homogenous. Smooth muscle cytoplasm contains large amounts of actin and myosin. Actin and myosin act as the main proteins involved in muscle contraction. Actin filaments attach to dense bodies spread throughout the cell. Dense bodies can be observed under an electron microscope and appea...
The type of muscle that has elongated, multinucleated cells and is under voluntary control is muscle. a) skeletal b) smooth c) cardiac The cells are striated in appearance a) skeletal muscle tissue b) cardiac muscle tissue c) smooth muscle tissue ...

The formation of fibroblast foci was observed in the model group by optical microscope. The ultrastructure in pulmonary tissue of the model group rats were changed and proliferated myofibroblasts with filaments were found in the alveolar septa by electron microscopy. The expression of alpha-SMA was ...
