Exercise 9: Muscular Tissue Flashcards
Is oval and centrally located
Nucleus
The fibers of this tissue have cross striation similar to the striated muscle tissue. The fibers are branching or anatomosing with one another appearing like a network of fibers with continuous cytoplasmic material.
Cardiac muscle
The cells of this type of muscle tissue are spindle-shaped each with a centrally located nucleus.
Smooth or visceral muscle tissue
are sometimes called contractile tissues. It is through the shortening and thickening of their contractile fibrillar components, the myofibrils, the muscular tissue perform mechanical work.
Muscle tissue
The fiber is completely enclosed with structural membrane, the sarcolemma and inside the sarcolemma is the
Sacroplasm
voluntary muscle attached to bones or skeleton.
Skeletal or striated
move the animal from one place to another or move the various parts of the body with respect to one contraction and are usually grouped into bundles.
Contraction of muscle cells
involuntary, non- striated composed of the walls the blood vessels and digestive tract.
Visceral or smooth
Each cell is surrounded by a mass of fibers called __________ which do not appear striated and are the contractile parts of muscle tissues.
Myofibrils
Types of muscle base on their microscopic appearance, nervous control and location
Skeletal or striated
Cardiac or striated
Visceral or smooth
are elongated and lie at the periphery of the cell.
Nuclei
involuntary muscle composed of the heart
Cardiac or striated
are the lighter bands of skeletal muscle cells
Isotropic
The darker bands
Anisotropic
Types of muscle tissue
Skeletal muscle tissue
Cardiac muscle tissue
Smooth or visceral muscle tissue
