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.

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.
There are two types of striated muscle: skeletal muscle and cardiac muscle. The skeletal muscles are voluntary muscles which allow for the movement of bones and joints, while cardiac muscles are involuntary, and found only in the heart. striated muscle is a muscle composed of thousands of units known as sarcomeres. Each sarcomere is composed of distinct bands of different material which give the muscle a striped or striated appearance when it is viewed at a high level of magnification.
