Nonarticulated

Nonarticulated refers to something that lacks joints or articulation. In biology, this term is often used to describe body parts or structures that are fixed and do not move relative to each other. For instance, some bones in the skull, like the sutures between cranial bones, are nonarticulated once fused, meaning they become immovable. This contrasts with articulated structures, such as the joints in the limbs, which allow for a range of motion.

In engineering and design, nonarticulated components are those that are rigid and cannot bend or flex. A nonarticulated arm on a robot, for example, would be a straight, solid piece of material that cannot be bent at any point. This is in opposition to an articulated arm, which would have multiple segments connected by joints, enabling it to move and position itself in complex ways. The concept of nonarticulation implies a lack of flexibility and movement at the point of connection or within the structure itself. It signifies a solid, singular, or fused state, as opposed to a segmented or jointed one. This distinction is important in fields ranging from anatomy to mechanical design, where the presence or absence of articulation dictates function and capability.
