Web18 Mar 2015 · Smooth muscle cells aggregate with their long axes parallel and staggered longitudinally, so that the wide central portion of one cell lies next to the tapered end of another. Such an arrangement achieves both close packing and a more efficient transfer of force from cell to cell. WebDescribe the characteristics of muscle tissue and how these dictate muscle function. By the end of this section, you will be able to: Identify the three types of muscle tissue; ... Smooth muscle cells have a single nucleus and no visible striations. (c) Cardiac muscle cells appear striated and have a single nucleus. From top, LM × 1600, LM × ...

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) Web16 Jun 2024 · These muscles maintain their tone for long periods of time. The main proteins responsible for their contraction are the thick, dark myosin filaments and thin, light actin filaments. Smooth muscles have a particular shape which is fusiform, as they have tapered ends. Being non-striated muscles, smooth muscles are more elastic than striated muscles.
