According to the geophysical planet definition, what makes a planet a planet is that it is a non-self-luminous celestial spheroidal body orbiting a star, free floating in space, or even orbiting another planet. In other words, what makes a planet a planet are its intrinsic characteristics.If an object is not a star and is large enough for its gravity to squeeze it into a round or nearly round shape, it is a planet. By this definition, Earthâs moon qualifies as a planet.ccording to the geophysical planet definition, what makes a planet a planet is that it is a non-self-luminous celestial spheroidal body orbiting a star, free floating in space, or even orbiting another planet.

Skeletal muscle is striated muscle tissue that is attached to bones. It is composed of fibers that look like a mixture of dark and light bands bundled together that run along the bone.here are three different types of muscle tissue within the body. Skeletal muscle is striated muscle tissue that is attached to bones. Skeletal muscle attaches to the bones. At the macroscopic level, the skeletal muscles are composed of a variety of layers.
Muscle can be described as striated or smooth. Striated includes skeletal and cardiac muscle. The striations result from the highly uniform organization of the fundamental elements of the contractile apparatus, that being the actin (thin) filaments and the myosin-containing (thick) filaments.dentify the three types of muscle: smooth, cardiac and skeletal; understand why the latter two are referred to as striated muscles. 3. Identify the myofibrils and cross-striations in striated muscle fibers. 4. Distinguish between smooth muscle and dense regular connective tissue. 5.
