Smooth muscle number of nuclei.

Smooth muscle may be studied using slide 029-1 smooth muscle ... Note central location of muscle nuclei. Note the "stacks" of mitochondria between myofibrils. Cardiac muscle is even richer than skeletal muscle in mitochondria (again, important for energy production). An intercalated disc is present in the upper left region of the picture.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.Skeletal muscle tissue develops through the fusion of individual myoblasts, or early muscle cells. This fusion results in a characteristic multinucleated structure. Because the cells are fused and multinucleated, they form a structural syncytium. Nuclei of skeletal muscle tissue are oval-shaped and located at the periphery of the cell.Within the brain, acetylcholine has involvement in memory, motivation, arousal, and attention. Acetylcholine originates from two major places in the brain: 1) basal forebrain and 2) the mesopontine tegmentum area. Acetylcholine originates in the basal forebrain from both the basal nucleus of Meynert and the medial septal nucleus.Jun 20, 2023 · This also holds true for the multinucleated skeletal muscle fiber, as the number of diploid cell nuclei scales sublinearly with fiber volume but linearly with the fiber surface area (Hansson et al., 2020a) . FIGURE 2: Nuclear number scales in direct proportion to the surface area. (Ai) DNA content (nuclear number) regressed on fiber volume ...

Abstract. The spatial density of mitochondria was studied by thin-section electron microscopy in smooth muscles of bladder, iris and gut in mice, rats, guinea-pigs and sheep. Morphometric data included areas of muscle cell profiles (~6,000 muscle cells were measured) and areas of their mitochondria (more than three times as many).This showed that nuclei of the Mdx muscle mostly resembled those from the uninjured and 14 d.p.i muscle, whereas the signature of 7 d.p.i myofibers was depleted (Fig. 4b).Smooth muscles that act like skeletal muscles but are controlled by autonomic nerves and hormones are _____. ... increase in the number of muscle cells. ...

Skeletal myofibers, which grow to become amongst the largest cells of the body attaining sizes ranging between 4.9 and 42 cm in the human hindlimb [1], are also unique for their level of multinucleation. Between several hundred and thousands of nuclei are acquired and accumulated per myofiber primarily during development, but also ...

Table 1. The mammalian skeletal muscle fiber (myofiber) is a peculiar syncytia as it possesses hundreds of nuclei. In a fully matured myofiber, most nuclei are positioned and spaced regularly at the periphery, just below the plasma membrane. 42,43 The spatial organization of these nuclei is not random.

Cardiac muscle cells have many nuclei. Skeletal muscle cells are long and cylindrical with many nuclei. Cardiac muscle cells are found in the heart and large blood vessels. Smooth muscle cells have T tubules.The nuclei are centrally situated like that of smooth muscle. Cardiac muscle sarcoplasm has a great amount of mitochondria to meet the energy demands. Similar to the skeletal muscle, cardiac muscle cells have an invaginating network of T-tubules and sarcoplasmic reticulum.Fiber length and size can vary considerably within a given muscle and between different muscles.
