The smooth muscle cell

WebSmooth muscle contains spindle-shaped cells 50 to 250 μm in length by 5 to 10 μm in diameter. These cells possess a single, central nucleus. Surrounding the nucleus and throughout most of the cytoplasm are the thick (myosin) and thin (actin) filaments. Tiny projections that originate from the myosin filament are believed to be cross bridges. WebThe main endogenous agonist of these cell receptors is norepinephrine (NE). The adrenergic receptors exert opposite physiologic effects in the vascular smooth muscle under …

WebApr 10, 2024 · The smooth muscle cells consist of long narrow and unbranched spindle-shaped fibres. Each fibre of the smooth muscle cells contains a thick oval nucleus in its thick middle part. The cross striation is absent in the smooth muscles, so their fibres look smooth hence it is named non-striated. WebThe type of muscle corresponds with their function. Striated muscles are better suited for bursts of expansion and contraction, while smooth muscles are better for handling smooth, sustained contractions. If the wrong type of muscle was in a certain part of the body, it would be very ineffective. ( 4 votes)
