Humans have an exoskeleton no coelem segmentation or jointed appendages

Human beings have jointed appendages. These appendages possess bones that are linked to each other with the help of skeletal muscles, which are attached to cord like tendons that in turn are linked with bones of the appendages.

The gravitational force between a mass and the Earth is the object's weight. Mass is considered a measure of an object's inertia, and its weight is the force exerted on the object in a gravitational field. On the surface of the Earth, the two forces are related by the acceleration due to gravity: Fg = mg
