Muscle tissue is characterized by properties that allow movement. Muscle cells are excitable; they respond to a stimulus. They are contractile, meaning they can shorten and generate a pulling force. When attached between two movable objects, such as two bones, contraction of the muscles cause the bones to move.

The heart consists mostly of cardiac muscle cells (or myocardium). The outstanding characteristics of the action of the heart are its contractility, which is the basis for its pumping action, and the rhythmicity of the contraction.

What are characteristics of connective tissues? Share three basic components: (1) specialized cells, (2) extracellular protein fibers and (3) a fluid known as ground substance.

Figure 1: Muscle Types. Cardiac and skeletal muscle are both striated in appearance, while smooth muscle is not. Both cardiac and smooth muscle are involuntary while skeletal muscle is voluntary.

Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions.

Anatomists name the skeletal muscles according to a number of criteria, each of which describes the muscle in some way. These include naming the muscle after its shape, size, fiber direction, location, number of origins or its action. The names of some muscles reflect their shape.

The characteristic of the pennate muscle is the alignment of the muscular fascicles in relation to its tendon. The fibres are attached obliquely, which allows a higher force at the expense of a smaller range of motion.

APPEARANCE : Frogs have the characteristics of: two bulging eyes; strong, long, webbed hind feet that are adapted for leaping and swimming; and smooth or slimy skin (generally, frogs tend to like moister environments than toads).

The 3 types of muscle tissue are cardiac, smooth, and skeletal.

As will soon be described, the functional unit of a skeletal muscle fiber is the sarcomere, a highly organized arrangement of the contractile myofilaments actin (thin filament) and myosin (thick filament), along with other support proteins. Figure 2. Muscle Fiber.

Muscle is one of the four primary tissue types of the body, and the body contains three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle (Figure 15.2). The primary function of all muscle tissue is movement.
