Muscle Tissue. Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts. The tissue is highly cellular and is well supplied with blood vessels. The cells are long and slender so they are sometimes called muscle fibers, and these are usually arranged in bundles or layers that are surrounded by connective tissue.Skeletal muscle fibers can be quite large for human cells, with diameters up to 100 μ m and lengths up to 30 cm (11.8 in) in the Sartorius of the upper leg. During early development, embryonic myoblasts, each with its own nucleus, fuse with up to hundreds of other myoblasts to form the multinucleated skeletal muscle fibers.

These myoblasts asre located to the periphery of the myocyte and flattened so as not to impact myocyte contraction. Myocyte: Skeletal muscle cell: A skeletal muscle cell is surrounded by a plasma membrane called the sarcolemma with a cytoplasm called the sarcoplasm. A muscle fiber is composed of many myofibrils, packaged into orderly units.Skeletal Muscle Tissue. The striations are evidence of the myofilaments inside the muscle fibers. The position of the nuclei and vascularity are also signs of muscle tissue. You observe a tissue under a microscope. There appears to be a lumen on one side of the tissue. Lining this lumen, the cells seem to have long, fingerlike projections.

The characteristics of skeletal muscle are the striations that can be seen in the fascicles. The other characteristic is that they can contract to produce ... Cardiac muscle cells generally only contain one nucleus, located in the central region. They contain many mitochondria and myoglobin. Unlike skeletal muscle, cardiac muscle cells are unicellular. These cells are connected to each other by intercalated disks, which contain gap junctions and desmosomes.

Find out the answer to the question "All muscle cells contain striations?" and more.Muscle: The Three Types of Muscle. Contractility is a fundamental property of cells and the majority of them contain essentially the same contractile machinery as that found in muscle cells. In muscle cells, however, a larger proportion of the cells' resources are given over to this function than in other cell types.Concept Review. Muscle is the tissue in animals that allows for active movement of the body or materials within the body. There are three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle. Most of the body's skeletal muscle produces movement by acting on the skeleton. Cardiac muscle is found in the wall of the heart ...All muscle cells contain striations. False.

Skeletal muscle fibers are classified into two types: type 1 and type 2. Type 2 is further broken down into subtypes. Type 1. These fibers utilize oxygen to generate energy for movement. Type 1 ...The muscle cell is actually a syncytium of hundreds of cells forming a muscle fiber that extends from origin to insertion., Sarcolemma, Sarcoplasm and more. Study with Quizlet and memorize flashcards containing terms like Each muscle cell is long, cylindrical, multinucleated, and may be striated.

Skeletal muscle cells are responsible for practically all movements that are under voluntary control. These cells can be very large (2–3 cm long and 100 μm in diameter in an adult human) and are often referred to as muscle fibers because of their highly elongated shape. Each one is a syncytium, containing many nuclei within a common cytoplasm.The other …Skeletal and cardiac muscle cells are called striated because they show an alternating series of bands. The repeating arrangement of their basic contractile unit, the sarcomere, produces these striations.. In all types of muscle, contraction is caused by the movement of myosin filaments along actin filaments.. The terms muscle cell and muscle fiber are synonymous.Note that sometimes the cross striations are not aligned all the way across the cell. This is because different myofibrils may not be aligned.

Skeletal muscle fibers are long, multinucleated cells. The membrane of the cell is the sarcolemma; the cytoplasm of the cell is the sarcoplasm. The sarcoplasmic reticulum (SR) is a form of endoplasmic reticulum.Smooth muscle is a type of non- striated muscle, found within the tunica media layer of arteries and veins, the bladder, uterus, male, female, and all animals, gastrointestinal tract, respiratory tract, the ciliary muscle and iris of the eye. The glomeruli of the kidneys contain a smooth muscle-like cell called the mesangial cell.

A single muscle cell contains many nuclei, which are pressed against the cell membrane. A muscle cell is a long cell compared to other forms of cells, and many muscle cells connect together to form the long fibers found in muscle tissue. Structure of a Muscle Cell. As seen in the image below, a muscle cell is a compact bundle of many myofibrils.

The cells are interconnected physically and electrochemically to act as a syncytium. Cardiac muscle cells contract autonomously and involuntarily. Smooth muscle is involuntary. Each cell is a spindle-shaped fiber and contains a single nucleus. No striations are evident because the actin and myosin filaments do not align in the cytoplasm.
