Smooth muscle number of nuclei.

Cardiac muscle is striated muscle that is present only in the heart. Cardiac muscle fibers have a single nucleus, are branched, and joined to one another by intercalated discs that contain gap junctions for depolarization between cells and desmosomes to hold the fibers together when the heart contracts. Contraction in each cardiac muscle fiber ...The position of nuclei in skeletal muscle cells (myo fibers) is of particular interest, since these cells are multinucleated, with up to hundreds of nuclei (myonuclei), evenly distributed along the cell surface. Mislocalized myonuclei have been associated with a variety of muscle diseases [3] that are characterized by reduced muscle size ...a. number of nuclei (one or multiple) in a smooth muscle cellb. presence of gap junctions in a smooth musclec. voluntary or involuntary contraction in a smooth muscled. shape of the smooth muscle cell e. presence of sarcomere in a smooth muscle cellf. length or duration of action potential/contraction in a smooth muscle cell.Slide 1: Muscle- Skeletal Longitudinal Section and Slide 2: Muscle-Skeletal Cross Section Yes, striates are present. There are multiple nuclei A long thread-like shape These muscles contract due to nerve stimuli. They then relax when the stimuli stops. This muscle tissue controls voluntary movements. Such as your head or neck.Typically, cardiomyocytes have a single, central nucleus, but two or more nuclei may be found in some cells. Cardiac muscle cells branch freely. A junction between two adjoining cells is marked by a critical structure called an intercalated disc , which helps support the synchronized contraction of the muscle ( Figure 19.2.1 b ).

The fibers are separated by collagenous tissue that supports the capillary network of cardiac tissue. The myofilaments of cardiac muscle are arranged in a similar pattern to skeletal muscle, resulting in cross ...In fact, it is known that nuclei in different positions of the myofibers have different functions and express different genes (Newlands et al., 1998). scRNA-seq and mass cytometry studies have defined the major mononuclear cell types present in skeletal muscle: fibroadipogenic progenitors (FAPs), tenocytes, endothelial cells, smooth muscle ...

A muscle cell, also known as a myocyte, is a mature contractile cell in the muscle of an animal. [1] In humans and other vertebrates there are three types: skeletal, smooth, and cardiac (cardiomyocytes). [2] A skeletal muscle cell is long and threadlike with many nuclei and is called a muscle fiber. [3] Muscle cells develop from embryonic ...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
