Nuclei are much more frequent and larger in smooth muscle and they are very; University of Waterloo ; BIOL 302 - Spring 2012. We have been discussing about cell specialization since the beginning of this article but did you know that there exist a process completely opposite to it? Usually, the cell changes to a more specialized type. Muscle cells. Neuron. While several associated proteins help, actin and myosin form thick and thin filaments which slide past each other to contract small units of a muscle cell. Learn. One cell cannot carry out all functions quick enough or effectively. It continues up to adulthood when the cells (adult stem cells) divide to replace cells and worn-out tissues. For example muscle cells have specialised so they have become very good at pulling and so cause movement. Skeletal muscle cells are long, cylindrical, multi-nucleated and striated. “Medical gallery of Blausen Medical 2014”. 9th - 10th grade . This quiz is incomplete! Smooth muscle is different from skeletal muscle in that the actin and myosin filament are not organized in convenient bundles. Actins, myosins, and associated proteins ofthe contractile systems ofthe different types ofmuscle cell can differ antigenically from each other (Holtzer et al., 1957). Edit. Edit. This image shows the internal organization of a muscle cell. The nerve impulse travels down the nerve cells to the neuromuscular junction, where a nerve cell meets a muscle cell. Adipose cell, connective-tissue cell specialized to synthesize and contain large globules of fat. Muscle Cell- Skeletal Muscle Skeletal muscle cells or striated or voluntary muscles Can shorten to move bones. In addition to that, these cells also contain a lot of mitochondria that sustain the high. They transport oxygen throughout the body. As seen in the image below, a muscle cell is a compact bundle of many myofibrils. Spirals and rings of lignin in the cell walls strengthen them to withstand pressure of water. Where is a root hair cell found? I clicked on this website after asking google “Why is cell specialisation important?” and it came up with this website but doesn’t tell me anything about why it’s important. Muscle cells also have extremely high numbers of mitochondria to produce ATP for force generation. In the embryo, a skeletal muscle fiber begins as a single cell, called a myoblast.Individual myoblasts begin to fuse with one another, forming elongated cells, called myotubes, in which dozens of nuclei are lined up in a central row (Fig. In doing scientific exploration, scientists found that an electrical current will stimulate a muscle cell, even if the cell is not in a living animal. 210 different types of cells in the human body.
