They differ by the presence or absence of striations or bands, the number and location of nuclei, whether they are voluntarily or involuntarily controlled, and their location within the body.Smooth muscle fibers are spindle-shaped (wide in the middle and tapered at both ends, somewhat like a football) and have a single nucleus; they range from about 30 to 200 μ m (thousands of times shorter than skeletal muscle fibers), and they produce their own connective tissue, endomysium.Smooth muscle is also present in the eyes, where it functions to change the size of the iris and alter the shape of the lens; and in the skin where it causes hair to stand erect in response to cold temperature or fear. Figure 1. Smooth Muscle Tissue. Smooth muscle tissue is found around organs in the digestive, respiratory, reproductive tracts ...Skeletal muscle hypertrophy is characterized histologically by an increase in myofiber diameter. This can sometimes be difficult to detect histologically. Hypertrophy occurs as a result of increased workload and can occur either focally, as a compensatory reaction following the loss or atrophy of surrounding muscle, or more extensively, as a physiologic response to increased exercise demands.

Smooth Muscle. Smooth muscle is made up of cells that contain a single central nucleus. The cells stick together and are connected by specialised cell junctions, called gap junctions. The cells are spindle shaped, and the nucleus is central. This diagram shows a few of the cells that can be seen in the stained section below.Each FC fuses with a specific number of FCMs (2-25) and establishes a unique muscle with a specific size, shape, tendon attachment, and innervation [12,13]. Each embryonic muscle is composed of a single muscle cell with a relatively small number of nuclei, which is ideal for investigating molecular events underlying myogenesis in great detail.Cardiac Cell Histology Cardiac cells - myocytes - are arranged in layers and are shorter than skeletal muscles - Cardiac muscle has properties of a skeletal muscle and of a smooth muscle - Cardiac muscle cell has 1-2 nuclei (myonuclei)Each FC fuses with a specific number of FCMs (2–25) and establishes a unique muscle with a specific size, shape, tendon attachment, and innervation [12,13]. Each embryonic muscle is composed of a single muscle cell with a relatively small number of nuclei, which is ideal for investigating molecular events underlying myogenesis in great detail.The fibres of striated muscle have a cylindrical shape with blunt ends, whereas those in smooth muscle are spindle-like with tapered ends. Striated muscle tissue has more mitochondria than smooth muscle. Both smooth muscle cells and cardiac muscle cells have a single nucleus, and skeletal muscle cells have many nuclei. Function

In visceral smooth muscles ( 356, 379 - 381 ), IP 3 Rs are expressed in greater quantity than RyRs with an overall stoichiometric ratio of IP 3 Rs to RyRs of ∼10-12:1, while in vascular smooth muscles the ratio is 3-4:1 ( 62 ).

Smooth muscle fibers are spindle-shaped and, unlike skeletal muscle fibers, have a single nucleus; individual cells range in size from 30 to 200 μ m. Smooth muscle fibers are often found forming sheets of tissue and function in a coordinated fashion due to the presence of gap junctions between the cells.

The type of muscle that has cells containing multiple nuclei (option C) is skeletal muscle. Unlike cardiac muscle cells and smooth muscle cells, which typically have a single nucleus, skeletal muscle cells are unique as they contain many nuclei. These muscle cells are long and fibrous and are commonly referred to as muscle fibers.

Smooth muscle fibers are spindle-shaped (wide in the middle and tapered at both ends, somewhat like a football) and have a single nucleus; they range from about 30 to 200 μm (thousands of times shorter than skeletal muscle fibers), and they produce their own connective tissue, endomysium.Although they do not have striations and sarcomeres, …Skeletal muscle is composed of syncytial myofibres, each containing hundreds of nuclei. Through genetic reduction of the number of nuclei per myofibre, the authors confirm that more nuclei produce ...Surprisingly, the results revealed an inverse relationship between nuclei numbers and reserve capacity.
