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.
Their major function is to give strength to the body and support it; they also produce movements. There are three major categories of muscles; Skeletal muscles Cardiac muscles, and Smooth muscles. These muscles are made up of muscular fibers. Muscle fibers are of two kinds: striated muscle fibers and non-striated muscle fibers. Muscles that contain striated muscle fibers are called striated muscle and muscles that contain non-striated muscle fibers are called non-striated muscles. The difference between striated and non-striated muscles is that in striated muscles, the contractile fibrils are aligned parallel, and their regions form stripes that are easily visible under a microscope, whereas non-striated muscles do not have stripes on them, they give a poor appearance under the microscope.
