What happens during a heart attack? When treating cardiomyopathy, the goal is to reduce symptoms that affect everyday life. The activation of many muscle fibers together causes muscles to contract, which in turn can produce movement. We recommend using a Similar to skeletal muscle, it has cross striations in its cells, but cardiac muscle has a single, centrally-located nucleus; the muscle branches in many directions. A soft tissue that composes muscles in animal bodies, and gives rise to muscles' ability to contract. Identify structural similarities between skeletal muscle and nervous tissue, focusing on prominent, specialized subcellular structures and organization of fibers. Figure 12.3.2 shows how the three types of muscle tissues appear under magnification. Projections from the cell body are either dendrites, specialized in receiving input, or a single axon, specialized in transmitting impulses. WebNervous Tissue. Biomaterials. These categories are epithelial, connective, muscle, and nervous. It transports O2, waste product. A nerve consists of a neuron and glial cells. Skeletal muscle has striations across its cells caused by the arrangement of the contractile proteins, actin and myosin, that run throughout the muscle fiber. Whether you are moving your eyes or running a marathon, you are using skeletal muscles. They are controlled by electrical impulses from specialized cardiac muscle cells in an area of the heart muscle called the sinoatrial node. Graptolithina Wikipedia.
